▼ Resumo: No Brasil, o efluente industrial produzido em maior quantidade é a vinhaça, caracterizada por altos níveis de ácidos orgânicos, fósforo, cálcio, potássio e magnésio. O reaproveitamento energético da vinhaça mostra-se como uma alternativa interessante para produção de biocombustíveis ou sub-produtos. Este trabalho avaliou o potencial da vinhaça como fonte de substrato e nutrientes para produção de álcoois e ácidos orgânicos voláteis (AOV) por meio fermentação em batelada utilizando consórcio anaeróbio (lodo de bovinocultura) pré-tratados com choque térmico (TT) e choque ácido-térmico (AT). Foram utilizados dois meios diferentes, de sacarose (S) e de vinhaça (V), sendo a sacarose a principal fonte de carbono. A vinhaça provou ser uma excelente fonte de nutrientes para os microrganismos envolvidos na fermentação butírica, uma vez que a adição de vinhaça melhora significativamente a produção de ácido butírico em comparação com meio de cultura sintético. As máximas concentrações de ácido butírico, iso-butírico e acético foram de 14,13 ± 0,77 g L-1 na amostra ATV B3; 10,34 ± 0,43 g L-1na amostra ATV B2 e; 4,13 ± 0,06 g L-1na amostra TTV B3, respectivamente. O rendimento dos AOV acético, iso-butírico e butírico e de etanol foi mais elevado nas amostras ATV B3 e TTV B3, atingindo valores máximos de 0,14; 0,28; 0,69 e; 0,26 g g-1 carboidratos totais, respectivamente. Não foram encontradas diferenças significativas entre métodos de pré-tratamento e enriquecimento de inóculo, AT e TT no que diz respeito a produção de ácido butírico e etanol. Em escala maior, operando em reator de 1,5 L, a fermentação de vinhaça bruta e melado de cana por consórcio microbiano AU mostrou potencial para produção de solventes como o butanol, uma vez que concentrações elevadas de ácido butírico foram produzidas, com concentração máxima, rendimento e produtividade de 13,85 g L-1; 0,64 g g-1 e; 199,98 mg L h-1, respectivamente. A caracterização microbiológica, pirosequenciamento, revelou a ocorrência em maior abundância de bactérias do gênero Clostridium, principalmente no consórcio AU e Lactobacillus mais abundante nos consórcios TT e AT. Foi identificada uma espécie conhecida pela produção de butanol, o C. pasteurianum no consórcio AU. Contudo, o presente trabalho representa um passo importante no desenvolvimento de um processo industrial para reutilização da vinhaça. A exploração de novos microrganismos e estudo dos fatores que interferem no processo de fermentação como pH, temperatura, nutrientes, densidade da cultura, cargas aplicadas e características do substrato, são fundamentais para o entendimento dos efeitos sinérgicos e antagônicos da associação de culturas; Abstract: In Brazil, industrial waste produced in the greatest amount is vinasse, characterized by high levels of organic acids, phosphorus, calcium, potassium and magnesium. The energy reuse of vinasse shows up as an interesting alternative for the production of biofuels or byproducts. This study evaluated the potential of vinasse as a source of substrate and nutrients for… Advisors/Committee Members: Silva, Ariovaldo José da, 1966- (advisor), Zaiat, Marcelo (committee member), Mariano, Adriano Pinto (committee member).

▼ Global energetic and environmental concerns have generated interest in the biological systems for the production liquid biofuels. Butanol is one such biofuel, which can be naturally produced by some Clostridia species. However, possible limitations in Clostridial engineering and large-scale fermentation have led to an examination of other potential organisms that might house this pathway for butanol production. As a robust industrial host and key model organism in the study of fundamental biological processes, the yeast Saccharomyces cerevisiae has been used to house the Clostridial ABE-butanol pathway. However, butanol yields and titres in this yeast are relatively low. Therefore, in this thesis, three distinct strategies were carried out with the goal of optimising butanol production in the strain of yeast (previously constructed in the Ashe lab) bearing the ABE-butanol pathway: 1. Mutation of genes involved in the regulation of carbon source usage. 2. Deletion of genes where the product is involved in the consumption of cytosolic acetyl-CoA (the starting precursor for the butanol synthetic pathway). 3. Targeted mutagenesis to improve the efficiency of the thiolase enzyme, which catalyses the condensation of 2x acetyl-CoA to initiate the ABE-butanol synthesis pathway. The results showed the first two strategies did not lead to improvements in butanol yields. However, increases of intracellular acetyl-CoA were observed in some mutant strains, even though butanol production did not increase in these strains. In order to make maximum use of the accumulating cytosolic acetyl-CoA, thiolase engineering in the butanol production yeast strain was pursued. The introduced changes caused an increase in butanol (about two fold). Overall, this project has used a minimal engineering approach by modulation of associated pathways or optimisation of the heterologous enzyme with a view to improve butanol production in yeast. To achieve high and scalable butanol production in yeast, a robust approach involving whole synthetic biology - Design, Build Test, and Learn will need to be adopted to create a more efficient yeast-butanol system.

Dois exemplos de combustíveis renováveis em uso atualmente são bioetanol e biodiesel. Novas alternativas de combustíveis incluem etanol celulósico e biobutanol. Estes apresentam vantagens pois contribuem para uma melhor produtividade e otimização do uso de biomassa. Possuem ainda boas propriedades que garantem o bom desempenho como combustíveis. A pesquisa e interesse industrial têm crescido sobre o biobutanol, com melhorias no processo tradicional de fermentação ABE (Acetona-Butanol-Etanol), desenvolvimento de novos microorganismos para aumentar o rendimento e técnicas de separação para isolar o solvente do meio fermentativo. Algumas companhias anunciaram planos para a introdução de biobutanol em misturas com gasolina no mercado norte-americano. O interesse por biobutanol no Brasil como combustível ainda é limitado, pois a infraestrutura de comercialização já é adaptada ao uso de bioetanol, e a maior parte da frota de carros circulante utiliza motores adaptados ao uso do bioetanol. A cana-de-açúcar pode ser utilizada como matéria prima no processo produtivo do biobutanol, capacitando o Brasil a tornar-se um importante exportador para suprir o biobutanol para outros países. Em curto prazo, o biobutanol poderá ser produzido no Brasil para substituir o petro-butanol como solvente em aplicações industriais ou para o mercado de exportação como combustível. O presente trabalho propõe o uso da técnica technology roadmapping para o planejamento estratégico do desenvolvimento do biobutanol, alinhando os objetivos de longo prazo com os recursos, linhas de financiamento e prioridades para atender as necessidades do processo de desenvolvimento.

Two examples of renewable fuels in use today are bioethanol and biodiesel. New alternatives on biofuels include cellulosic ethanol and biobutanol. They present several advantages over the conventional biofuels, either in terms of better productivity and optimization of the use of biomass, as well as higher performance attributes. The research and industrial interest has grown on biobutanol, with improvements on the traditional ABE fermentation process, on the development of new microorganism strains to improve yield, and separation techniques to isolate the solvent. Companies have announced plans for the introduction of biobutanol in blends with gasoline in the north-american market. The interest on biobutanol as a fuel in Brazil is still limited, since the infrastructure is tailored to bioethanol already, and most of the car fleet uses engines adapted to this fuel. Sugar cane can be used as a potential feedstock in the butanol production process, enabling Brazil to become a key exporter to supply biobutanol to other countries. For the short future biobutanol will be produced in Brazil to replace petro-butanol as a solvent in industrial applications only, or for the export market as a fuel. This work proposes the use of technology roadmapping as a technique for long term strategic planning of the biobutanol development, aligning long term goals with the resources, funding, and…

▼ Resumo: O álcool n-butanol é uma substância orgânica que tem sido proposta como combustível alternativo para motores à combustão interna. Melhorias em seu processo de produção como biocombustível, por meio de processos de fermentação ABE, a partir da biomassa, chamam a atenção para sua sustentabilidade econômica e ambiental; por outro lado, suas características físico-químicas e de queima, próximas à da gasolina e do diesel comerciais, sugerem seu uso combinado ou como substituto dos mesmos. Apesar disso, ainda se sabe pouco acerca das características de sua combustão, motivando a pesquisa na área. O etanol, por sua vez, é um biocombustível extensamente utilizado em motores de ciclo Otto, principalmente no Brasil e nos Estados Unidos, sendo produzido por processos eficientes de fermentação, inclusive como subproduto da produção de butanol no processo ABE; por suas características físico-químicas, de produção e queima, propõe-se que seja misturado ao n-butanol em aplicações comerciais. O presente estudo compara esquemas de cinética química da queima em ar de n-butanol e etanol, entre si e em relação a dados experimentais disponíveis na literatura, por meio da simulação de chama laminar unidimensional pré-misturada no pacote REGATH (EM2C/CNRS - França). Em seguida, um novo esquema combinado é desenvolvido, que apresenta boa concordância com resultados experimentais da literatura para ambos os combustíveis nessas condições. Por fim, são levantadas curvas características da chama de misturas entre os compostos em diversas proporções, que poderão ser comparadas com dados experimentais em futuros trabalhos; Abstract: The alcohol n-butanol is an organic substance being proposed as an alternative fuel for internal combustion engines. Improvements in its production as a biofuel, through ABE fermentation processes, grow attention for its economic and environmental sustainability; on the other hand, its physicochemical and burning characteristics, close to those of commercial gasoline and diesel, suggest its usage as an additive or a substitute fuel. However, relatively few is known about its combustion characteristics, thus motivating research in that area. Ethanol, instead, is a biofuel widely used in Otto engines, especially in Brazil and the United States, being produced by efficient fermentation processes, and is occasionally a by-product of the butanol formation (ABE process); due to its physicochemical, burning and production characteristics, the addition of this fuel to butanol in commercial applications is proposed. The present study compares chemical kinetic schemes for the burning on air of n-butanol and ethanol, between each other and against experimental data available in the literatures, through simulations in one-dimensional premixed flame configuration in the REGATH package (EM2C/CNRS - France). Further, a new combined scheme is developed, presenting good agreement with experimental results from the literature for both fuels in these conditions. In the end, theoretical data for the flame of mixtures between… Advisors/Committee Members: Santos, Rogério Gonçalves dos, 1978- (advisor), Bizzo, Waldir Antônio (committee member), Júnior, Amir Antônio de Oliveira (committee member).

▼ Butane-grown Pseudomonas butanovora oxidized butane by a soluble butane monooxygenase through the terminal pathway yielding 1 -butanol as the predominant product. Alcohol dehydrogenases (ADHs) involved in butane oxidation in P. butanovora were purified and characterized at the biochemical, genetic and physiological levels. Butane-grown P. butanovora expressed a type I soluble quinoprotein 1 -butanol dehydrogenase (BOH), a soluble type II quinohemoprotein 1 -butanol dehydrogenase (BDH) and an NAD⁺-dependent secondary ADH. Two additional NAD⁺-dependent secondary ADHs were also detected in cells grown on 2-butanol and lactate. BDH was purified to near homogeneity and characterized. BDH is a monomer of 66 kDa consisting of one mole of pyrroloquinoline quinone (PQQ) and 0.25 mole of heme c as the prosthetic groups. BOH was partially purified and its deduced amino acid sequence suggests a 67-kDa ADH containing a PQQ as a cofactor. BOH and BDH exhibited high activities and preference towards I -butanol and fair preference towards butyraldehyde. While BDH could not oxidize 2-butanol, BOH is capable of 2-butanol oxidation and has a broader substrate range than that of BDH. Genes encoding BOH and BDH and their deduced amino acid sequences were identified. BOH and BDH mRNAs and 1-butanol oxidation activity were induced when cells were exposed to butane. Primary C₂ and C₄ alcohols were the most effective inducers for boh and bdh. Some secondary alcohols, such as 2-butanol, were also inducers for BOH mRNA, but not for BDH mRNA. Insertional inactivation of boh or bdh affected unfavorably, but did not eliminate, butane utilization in P. butanovora. The P. butanovora mutant strain with both boh and bdh genes disrupted was unable to grow on butane and 1-butanol. This result confirmed the involvement of BOH and BDH in butane and 1-butanol metabolism in P. butanovora. Roles of B011 and BDH in butane and 1-butanol metabolism were further studied at the physiological level. There are no substantial differences between BOH and BDH in the mRNA expressions in response to three different 1- butanol levels tested and in their abilities to respond to 1-butanol toxicity. Different bioenergetic roles of BOH and BDH in butane and 1-butanol metabolism were suggested. A model of 1 -butanol- dependent respiratory systems was proposed where the electrons from 1 -butanol oxidation follow a branched electron transport chain. The role of BOH was suggested to function primarily in energy generation because B011 may couple to ubiquinone with the electrons being transported to a cyanide-sensitive terminal oxidase. BDH may be more important in the detoxification of 1 -butanol because the electrons from BDH may be transferred to a terminal oxidase system that is less sensitive to cyanide, which is not capable of energy generation.

▼ Catalytic Distillation for the synthesis of tertiary butyl alcohol (TBA) is investigated in this thesis. The solvent, ethylene glycol, is proposed as a means of overcoming challenges, which limit the potential benefits of the application of reactive separation for TBA. The proposed action of the solvent is that of extractive distillation entrainer, thus a new unit operation of Catalytic Extractive Distillation (CED) is suggested. The solubility of isobutylene in water, TBA, and ethylene glycol and their binary andternary mixtures, at different temperatures, is measured and correlated. The solubility is found to be highly non-linear in solutions containing TBA. The kinetics of isobutylene hydration over Amberlyst 15 is characterised in the presence of ethylene glycol. The solvent is found to promote reaction rate, however it is also found to compete for reaction with isobutylene. Water is found to strongly inhibit the reaction of ethylene glycol and isobutylene. The selectivity ratio of TBA to by products is determined and found to improve with increased temperature and lower solvent concentration. Bale packing is chosen as catalytic distillation hardware for the containment of Amberlyst 15 and its two-phase fluid dynamics characterised for the first time. Raschigrings are used as a benchmark for the study. Bale packing is found to exhibit two ranges of backmixing behaviour in the pre-loading regime. This behaviour is attributed to the three levels of porosity of the hardware and indicative of low rates of catalyst/liquid renewal. The effectiveness of ethylene glycol as extractive distillation entrainer for the separationof the TBA/water azeotrope over Bale packing is investigated and the solvent found to be highly effective. The mass transfer resistances to isobutylene transport are determined for countercurrent fixed bed reactor (CFBR) application of Bale packing. It is found that ethylene glycol improves mass transfer coefficients attainable. Catalytic Extractive Distillation is implemented over Bale packing and the ability of the solvent to improve reaction rates and purity of TBA demonstrated. However, the reaction rates achieved have much scope for improvement through increased isobutylene availability. In response to poor liquid renewal of static packing such as Bale packing and the necessity of improved isobutylene transport a new form of catalytic distillation reactor design is proposed, the Basket Impeller Column (BIC). The BIC combines the mass transfer benefits of a rotating basket reactor with that of a dual flow column. Capacity of the new hardware is determined and correlated. Separation and reactive separation aredemonstrated to be feasible. It is found that Damköhler number can be varied directly using the additional process variable of speed of rotation.

Óxido e fosfato de nióbio, calcinados em diferentes temperaturas, foram usados como catalisadores na reação de desidratação de 1-butanol, onde o efeito da temperatura de reação, da massa de catalisador e da vazão de butanol sobre a conversão e seletividade a butenos foram avaliadas através de um plano experimental. Foram caracterizadas as propriedades cristalográficas dos catalisadores. A maioria dos catalisadores apresentaram uma estrutura amorfa, mas algumas amostras apresentaram uma estrutura cristalina quando calcinadas em maiores temperaturas, 500 e 850 °C para o NbO e NbP, respectivamente. Nos testes reacionais, observou-se que o aumento da temperatura de calcinação dos catalisadores reduziu a conversão de 1-butanol. O catalisador fosfato de nióbio apresentou maior atividade, já que foi obtida uma conversão similar à do óxido de nióbio com uma massa 5 vezes menor, indicando a presença de sítios ácidos mais ativos. Além disso, a variável reacional que teve maior efeito na conversão foi a vazão de alimentação de 1-butanol; e seu aumento causou um decréscimo nos valores de conversão. Este comportamento indicou que a ordem aparente da reação é menor que um, o que foi confirmado por um modelo cinético baseado em lei de potência, o qual ajustado aos dados experimentais resultou em uma ordem aparente em torno de zero Equações fenomenológicas de velocidade de reação baseadas no modelo LHHW foram desenvolvidos. O teste estatístico F de Fisher foi utilizado para comparar os modelos fenomenológicos obtidos: para o óxido de nióbio calcinado em 400 °C o modelo heterogêneo que leva em conta apenas a adsorção de butanol foi considerado o mais adequado; para o fosfato de nióbio calcinado em 400 °C o modelo heterogêneo que leva em conta a adsorção de butanol e de água foi o mais adequado. Para ambos os catalisadores, com exceção do NbO calcinado em 500 °C, foi observada uma significativa isomerização de 1-buteno a 2-buteno, principalmente nas condições que foi obtida uma maior conversão de butanol. Este fato comprova a elevada força ácida destes catalisadores. A seletividade a 2-buteno foi maior ou igual a 1-buteno em todas as temperaturas e condições de reação com fosfato de nióbio. Para o óxido de nióbio, a seletividade a 2-buteno foi maior em poucas condições reacionais.

Most catalysts presented an amorphous structure, but some samples presented a crystalline structure when calcined at higher temperatures, 500 and 850 °C for NbO and NbP, respectively.

▼ Recent research has shown that butanol, instead of ethanol, has the potential of introducing a more suitable blend in diesel engines. This is because butanol has properties similar to current transportation fuels in comparison to ethanol. However, the main downside is the high cost of the butanol production process. Acetone-butanol-ethanol (ABE) is an intermediate product of the fermentation process of butanol production. By eliminating the separation and purification processes, using ABE directly in diesel blends has the potential of greatly decreasing the overall cost for fuel production. This could lead to a vast commercial use of ABE-diesel blends on the market. Research has been done in the past five years concerning spray and combustion processes of both neat ABE and ABE-diesel mixtures. Additionally, different compositions of ABE mixtures had been characterized with a similar experimental approach. This thesis reviews the production of ABE and characterization of its spray and combustion processes. The results obtained during the recent four years will also be presented. The main focus of this paper is to review the efforts made in fundamental spray research under quasi-steady flow field environments provided by a high-pressure, high-temperature constant volume chamber. In-cylinder pressure traces were calculated to derive apparent heat release rates, high-speed Mie-scattering images were acquired to characterize liquid spray penetration, and natural flame luminosity was also captured to depict spatial and temporal soot distribution. It is observed that the acetone content has a major influence in the combustion behavior of the ABE mixture. An increased content of acetone will lead to a significantly advanced combustion phasing. Butanol, as another important species in the ABE mixture, is able to compensate the advancing effect caused by acetone and ethanol. More importantly, butanol can increase the overall energy density of the mixture, which makes the property of the mixture closer to that of current transportation fuels. In addition, the underlying challenges faced in this area of research are described. Additionally, the performance and emissions of acetone-butanol-ethanol (ABE)/diesel mixtures in an AVL 5402 single cylinder diesel research engine under various engine operating conditions were investigated in this study. The experiments were conducted at three different speeds (1200, 1500, and 2000 RPM) and different injection quantities (loads) (15, 20, and 25 mg/cycle). The fuels tested in these experiments were pure diesel, ABE10, and ABE20. The acetone-butanol-ethanol (ABE) was blended in a 3:6:1 ratio. ABE10 and ABE20 consist of 10% acetone-butanol-ethanol mixture and 90% diesel by volume and 20% ABE is mixed with 80% diesel by volume, respectively. The results showed a promising future for ABE-diesel mixtures as an alternative transportation fuel. There was improved thermal efficiency even with relatively small ABE blending ratios and a slight reduction in power output due to the lower… Advisors/Committee Members: Hansen, Alan C. (advisor).

▼ Resumo: A crescente demanda por fontes de energia renováveis vem direcionando esforços e interesses por pesquisas focadas no desenvolvimento de biocombustíveis, a partir da digestão de resíduos provenientes de atividades agrícolas e agroindustriais. Neste contexto, a digestão anaeróbia pode ser direcionada para a produção e aproveitamento de subprodutos intermediários com alto valor agregado, como, por exemplo, etanol e butanol. O objetivo geral deste trabalho foi avaliar o desempenho de reatores anaeróbios de leito fixo e fluxo ascendente no tratamento de água residuária, visando à produção biológica de butanol e etanol a partir de uma cultura mista de micro-organismos selvagens. Foram utilizados dois reatores anaeróbios de leito fixo, com volume total de 3,77 litros. O primeiro reator foi mantido em condição acidogênica e o segundo em condição solventogênica. Os reatores foram operados em cinco diferentes etapas com tempo detenção hidráulica (TDH) de 2, 4 e 12 h e alimentados com água residuária sintética preparada para resultar em DQO em torno de 500 mg L-1, 1.000 mg L-1, 4.000 mg L-1 e 12.000 mg L-1, tendo como principal fonte de carbono sacarose. Além disso, foram avaliadas duas condições de temperaturas diferentes, ambiente (variando de 25ºC a 30ºC) e controlada (35ºC). Em cada etapa também foi avaliada a influência do efeito da recirculação do biogás no desempenho dos reatores, operando-os por um período de 30 dias sem recirculação de biogás e 30 dias com recirculação de biogás. Os resultados mostraram que a suplementação de bicarbonato de sódio no preparo do afluente auxiliou no aumento da capacidade de tamponamento do sistema e a recirculação de biogás favoreceu a estabilidade nos valores de pH durante todo o período experimental nessa condição. A variação crescente do tempo de detenção hidráulica (TDH) e da concentração de matéria orgânica (DQO) conduziu a um aumento na concentração de ácidos voláteis totais (AVT) e na concentração de produtos intermediários resultante da fermentação da sacarose. A concentração média de AVT variou de 89,3 mg L-1 da etapa I para 147,0 mg L-1 na etapa II, quando houve aumento do TDH e da DQO afluente. A variação da temperatura não influenciou a produção de AVT, na etapa III na qual a temperatura foi variável a concentração média de AVT detectada no efluente foi 546,0 mg L-1 e na etapa IV, com temperatura mantida em 35°C a concentração média de AVT no efluente foi 530,4 mg L-1. O melhor desempenho na produção de etanol foi verificado no reator solventogênico, com o pH em torno de 4,5, quando mantido com temperatura controlada a 35°C, TDH de 4 horas e taxa de carregamento orgânico (TCO) de 24 g DQO m-3d-1, sem recirculação de biogás. Nessa condição a concentração média de etanol detectada no efluente foi de 929,52 mg L-1. A produção de etanol não correspondeu ao aumento da TCO aplicado na etapa V, mantendo a concentração média de 993,35 mg L-1 na fase com recirculação de biogás. Butanol foi detectado em concentrações muito baixas, é provável que as condições de pH, tipo de… Advisors/Committee Members: Silva, Ariovaldo José da, 1966- (advisor), Zaiat, Marcelo (committee member), Nour, Edson Aparecido Abdul (committee member).

In the current study, a novel non-acetone forming butanol and ethanol producer Was isolated and identified. Based on the 16s rDNA sequence BLAST and phylogenetic analyses, it was found to have high similarity with the reported hydrogen producing strains of Clostridium sporogenes. Biochemical studies revealed that it is lipase and protease positive. The lipolytic and proteolytic properties are the very important characteristics of Clostridium sporogenes. Sugar utilization profile studies were positive for glucose, saccharose, cellobiose and weakly positive result to xylose. This study demonstrated C. sporogenes BE01, an isolate from NIIST is having potential to compete with existing, well known butanol producers with the advantage of no acetone in the final solvent mixture. Rice straw hydrolysate is a potent source of substrate for butanol production by C. sporogenes BE01. Additional supplementation of vitamins and minerals were avoided by using rice straw hydrolysate as substrate. Its less growth, due to the inhibitors present in the hydrolysate and also inhibition by products resulted in less efficient conversion of sugars to butanol. Calcium carbonate played an important role in improving the butanol production, by providing the buffering action during fermentation and stimulating the electron transport mediators and redox reactions favoring butanol production. Its capability to produce acetic acid, butyric acid and hydrogen in significant quantities during butanol production adds value to the conversion process of lignocellulosic biomass to butanol. High cell density fermentation by immobilizing the cells on to ceramic particles improved the solvents and VFA production. Reduced sugar utilization from the concentrated hydrolysate could be due to accumulation of inhibitors in the hydrolysate during concentration. Two-stage fermentation was very efficient with immobilized cells and high conversions of sugars to solvents and VFAs were achieved. The information obtained from the study would be useful to develop a feasible technology for conversion of lignocellulosic biomass to biobutanol.

▼ With the rising concerns of energy crisis, biofuel production becomes a very popular topic. As a possible replacement to transportation fuel, butanol attracted more attention because of its similar properties to automobile gasoline. Its low hygroscopicity and low vapor pressure may prevent increase in moisture content in butanol and make butanol a safe and environmentally friendly biofuel. Butanol can be produced by clostridia through acetone-butanol-ethanol (ABE) fermentation. However, this practice was not economically feasible with low titer, yield and productivity. The objectives of this study were to develop enhanced butanol production from ABE fermentation in continuous FBB by mutants of C. beijerinckii, and to explore the possibility of producing butanol by metabolic engineered hosts. A stoichiometric model was developed for the analysis of the metabolic pathway in ABE fermentation. The model helped process development by predicting the maximum butanol yield based on mass and energy balance at steady state in continuous process. In the stoichiometric analysis, the uptake of butyric acid was shown to benefit butanol production by reducing required energy to produce butanol. Two mutants of C. beijerinckii were cultured in continuous fermentation with butyric acid as a supplement in the medium under different conditions. At a high dilution rate of 1.88 h-1, asporogenic C. beijerinckii ATCC 55025 in the fibrous bed bioreactor (FBB) was able to utilize glucose and butyrate and steadily give a high butanol productivity of 17.29 g/(L*h), which was 170 folds higher than that in conventional batch fermentation. A new strain isolated from C. beijerinckii ATCC 55025 in repeated-batch culture in the FBB, C. beijerinckii JB200, was able to increase butanol titer to 12 g/L in continuous fermentation. In continuous fermentation, fibrous bed bioreactor (FBB) was used to help cell immobilization at high cell density. C. beijerinckii mutants were able to be retained at high cell density (>100 g dried weight/L) and steadily produce butanol without contamination or degeneration using both glucose and butyric acid. Besides solvent producing clostridia, metabolically engineered Clostridium tyrobutyricum could actively produce butanol over six repeated batches in the FBB using glucose and/or xylose. In batches with only xylose, more butanol was produced at 7.12 g/L with a higher yield with the slower cell growth that made the foreign enzyme competitive to the native enzyme for butyryl CoA. A pilot scale FBB was constructed for the evaluation of the feasibility of large scale butanol production in the FBB. Two batch fermentations were operated and the results of ABE fermentation were similar to those at lab scale. ABE fermentation at pilot scale was able to produce butanol at ~9.1 g/L with media containing glucose and butyric acid. In summary, continuous butanol production with improved productivity from ABE fermentation with supplement of butyric acid as additional carbon source in the FBB was… Advisors/Committee Members: Yang, Shang-Tian (Advisor).

▼ Recently, with the concerns of unstable crude oil supply, rapid increase in gasoline prices and severe climate changes, higher alcohols (alcohols with more than two carbons) have gained interests for their potentials in replacing petroleum as new generation transportation fuels. Among all these candidates, n-butanol as a four carbon solvent has received the most attention because it shares very similar characteristics with gasoline and can be naturally produced by solventogenic Clostridia via Acetone-Butanol-Ethanol (ABE) fermentation. However, butanol production by these native producers suffers from low titer and yield due to inefficient substrate conversion and butanol cytotoxicity upon cell growth and metabolism. Also, the necessity of generating byproducts during fermentation significantly reduces butanol titer and product selectivity, and therefore, increases the cost for butanol recovery through distillation. In order to commercialize biobutanol as economically as petroleum-based processes, a more optimized overall fermentation strategy is highly desirable. Therefore, the goal of this study was to establish cost-effective fermentation processes for higher alcohols production through various approaches, including inexpensive feedstock utilization, process optimization employing external driving forces, and new strain development. First, the stability of hyper-butanol-producing strain Clostridium acetobutylicum JB200 was validated by long-term repeated batch fermentation with cells immobilized in a fibrous bed bioreactor using sucrose as substrate. Its stable fermentation performance using low-cost sugarcane juice with a high butanol titer (16¿20 g/L), yield (~0.21 g/g sucrose) and productivity (~0.32 g/L¿h) indicated that JB200 is a promising strain for industrial application. Then, the effect of extra driving forces provided by artificial electron carrier addition on butanol production by metabolically engineered Clostridium tyrobutyricum strain Ct¿ack-adhE2 was studied. The results suggested that artificial electron carriers can remarkably increase butanol titer and yield, while reduce the generation of byproducts. In addition, metabolic engineering of acidogenic C. tyrobutyricum were conducted to examine its feasibility as an isopropanol producer. A final isopropanol titer of 4.28 g/L in free-cell fermentation was achieved and an in vivo fluorescence based gene expression reporter system was developed to facilitate future gene manipulation in C. tyrobutyricum and other anaerobic microorganisms. This project demonstrated that by applying low-cost substrates, extra driving power as well as strains with high fermentation performance, the input-output ratio of butanol production via fermentation can be further enhanced to compete with petroleum-based processes. Meanwhile, for isopropanol production, more studies of solvent-producing gene regulation, speed-limiting-step enzyme activities, and redox balance in C. tyrobutyricum are still required.

▼ Resumo: Neste trabalho, foi feita uma revisão onde se apresentaram as características e propriedades do butanol sob o ponto de vista geral de um álcool produzido industrialmente e também do ponto de vista específico de um biocombustível. Uma visão geral sobre os meios de produção atuais desse álcool (via síntese química ou via fermentação) foram apresentadas bem como estudos atuais para melhorar o processo acetona-butanol-etanol (ABE), que é o mais difundido para a produção do biobutanol. Alguns tópicos de trabalhos de outros autores focados na cinética química de butanol foram brevemente introduzidos e, a partir destas análises, estudou-se o n-butanol dando ênfase na sua aplicação como biocombustível automotivo. Verificou-se que existe pouca informação sobre o desempenho de motores trabalhando com este álcool, dificultando a avaliação de suas vantagens em relação a outros combustíveis. Essa dificuldade foi contornada com o uso de simulação numérica, em especial modelos 1D, para representar todo o motor e visualizar o seu desempenho sob diferentes condições de operação e funcionando com diferentes combustíveis. Um motor, abastecido com mistura n-butanol-gasolina, foi modelado usando GT-Power, um código 1D para simulação de motores de combustão interna. Foram usadas medições feitas nesse motor para calibrar os resultados e ajustar a propriedades do combustível. Comparando o desempenho do motor abastecido com uma mistura BU40 (40% de butanol e 60% de gasolina), observou-se que ele apresenta níveis de potência e torque inferiores ao motor abastecido com etanol, porém similares ao motor abastecido com a mistura gasolina mais etanol e superiores ao motor abastecido com gasolina pura. O motor com BU40 também apresenta menores níveis de pressão de combustão, o que representa um menor carregamento mecânico nos componentes do motor. Em termos de eficiência, o motor com BU40 se apresenta no mesmo nível do motor rodando com mistura gasolina etanol e inferior ao motor com etanol; Abstract: In this work, a review is done presenting the characteristics and properties of butanol from the general point of view of an industrially produced alcohol and also from the specific point of view of a biofuel.

Some topics from articles of other authors focused on the chemical kinetics of butanol were briefly introduced and starting from these analyzes, n-butanol was studied with emphasis on its application as automotive biofuel.

Para os combustíveis primários (combustíveis puros) etanol, n-butanol e n-decano: como primeira parte, foram comparados os dados medidos da velocidade em função da razão de equivalência com dados experimentais de literatura e dados obtidos por simulações numéricas (chama 1-D pré-misturada). As condições iniciais de teste e simulação foram de 100 kPa de pressão e 400 K de temperatura em função da razão de equivalência no intervalo 0,6 - 1,4 com passo de 0,1. Os dados medidos da velocidade de chama laminar se aproximaram com dados experimentais encontrados na literatura, além disso, os dados simulados também deram boa aproximação com os dados medidos. Como segunda parte, foram feitos ensaios com 100 kPa de pressão inicial e razão de equivalência fixa e igual a 1,0 em função da temperatura inicial no intervalo 300 - 400 K com passo de 25 K. Os dados medidos da velocidade de chama laminar aumentam com o aumento da temperatura da mistura inicial. Para o caso do combustível binário (mistura de dois conbustíveis puros) n-butanol/etanol, com as seguintes concentrações: o B20 (20 % de n-butanol e 80 % etanol), B40 (40 % de n-butanol e 60 % etanol), B60 (60 % de n-butanol e 40 % etanol) e B80 (80 % de n-butanol e 20 % etanol), as medições da velocidade foram feitos com temperatura e pressão inicial de 400 K e 100 kPa respectivamente, em função da razão de equivalência no intervalo 0,8 - 1,3 com passo de 0,1. Os dados medidos da velocidade de chama laminar em função da razão de equivalência diminuíram com o aumento da concentração do n-butanol, além disso, a mesma tendência ocorreu com os dados de simulação para as condições de teste; Abstract: The present work aims to present a study of the laminar flame velocity measurements for blends: air/ethanol and air/n-butanol, presented in the literature as a simulacrum of biodiesel, for air/n-decane, presented in the literature as simulacrum of kerosene, or as the main component of diesel simulations, and for ar/n-butanol/ethanol with different concentrations of n-butanol (by volume).

▼ Resumo: O setor de papel e celulose tem dado claros indícios de mudança em sua estratégia industrial e comercial. O anseio pela produção de novos produtos a partir de fonte renovável (como por exemplo, cavacos de eucalipto) tem sido uma das principais forças que estão levando o setor buscar por outras tecnologias. Dentre estes produtos, destacam-se os combustíveis como etanol e butanol, que podem ser produzidos pela fermentação dos açúcares celulósicos presentes no eucalipto. Devido à toxicidade dos próprios produtos, as fermentações tendem a ocorrer em meios reacionais diluídos, que implicam em elevados dispêndios energéticos e produção de vinhaça elevada, que podem reduzir a atratividade econômica de projetos. Aliada a motivação de se criar uma tecnologia que supere a problemática da inibição, está o interesse econômico em processos flexíveis, que permitem a criação de um negócio robusto frente a oscilações do mercado. Sendo assim, este projeto de caráter exploratório busca obter os principais rendimentos de um processo de fermentação flexível e intensivo. Em um primeiro momento, avaliou-se a produção de meio de cultivo de micro-organismos a partir de eucalipto. Para tanto, pré-tratou-se eucalipto com ácido sulfúrico diluído a diversas condições, seguido de uma hidrólise enzimática. Para uma hidrólise enzimática com 10% de teor de sólidos, foram alcançados concentrações baixas de glicose ¿ na faixa de 5 g/L ¿ e rendimentos globais de processo em glicose (pré-tratamento e hidrólise enzimática) na faixa dos 6%. Suplementou-se o caldo com glicose sintética para a realização dos ensaios de fermentação alcoólica para a produção de acetona, n-butanol e etanol (ABE). Avaliou-se três modos de operação: (1) fermentação batelada, (2) fermentação batelada com aplicação de vácuo intermitente e (3) fermentação semi-batelada com aplicação de vácuo intermitente (apenas na fermentação etanólica). Para a fermentação etanólica, observou-se que o tempo de reação diminuiu em 3h comparando batelada com batelada mais vácuo intermitente, aumentando a IV produtividade de 2,66 g/Lh para 3,20 g/L.h. Para os ensaios semi-batelada com vácuo intermitente, a produtividade foi inferior (1,74 g/Lh) pois o fornecimento de substrato era inferior a taxa de metabolização, levando a períodos de inatividade do micro-organismos. Este problema, no entanto, pode ser contornado, ministrando-se um substrato mais concentrado ou ultrapassando-se o volume inicial de fermentação. Com relação à fermentação ABE, verificou-se que a metabolização de substrato rico em pentoses ocorre muito lentamente (cerca de 84h totais) com baixas conversões do substrato (cerca de 40%), não justificando uma operação com vácuo. Já a fermentação de substrato com hexoses e pentoses é concluída após 72h de operação em batelada, com produtividade de 0,178 g/Lh de ABE. A aplicação de vácuo no mesmo ensaio aumentou a produtividade do processo para 0,293 g/Lh. Com este trabalho, observou-se que a utilização da tecnologia a vácuo leva ao aumento de produtividade em ambos os processos… Advisors/Committee Members: Mariano, Adriano Pinto, 1978- (advisor), Maciel Filho, Rubens (committee member), Santos, Samantha Christine (committee member).

▼ Resumo: O setor de papel e celulose tem dado claros indícios de mudança em sua estratégia industrial e comercial. O anseio pela produção de novos produtos a partir de fonte renovável (como por exemplo, cavacos de eucalipto) tem sido uma das principais forças que estão levando o setor buscar por outras tecnologias. Dentre estes produtos, destacam-se os combustíveis como etanol e butanol, que podem ser produzidos pela fermentação dos açúcares celulósicos presentes no eucalipto. Devido à toxicidade dos próprios produtos, as fermentações tendem a ocorrer em meios reacionais diluídos, que implicam em elevados dispêndios energéticos e produção de vinhaça elevada, que podem reduzir a atratividade econômica de projetos. Aliada a motivação de se criar uma tecnologia que supere a problemática da inibição, está o interesse econômico em processos flexíveis, que permitem a criação de um negócio robusto frente a oscilações do mercado. Sendo assim, este projeto de caráter exploratório busca obter os principais rendimentos de um processo de fermentação flexível e intensivo. Em um primeiro momento, avaliou-se a produção de meio de cultivo de micro-organismos a partir de eucalipto. Para tanto, pré-tratou-se eucalipto com ácido sulfúrico diluído a diversas condições, seguido de uma hidrólise enzimática. Para uma hidrólise enzimática com 10% de teor de sólidos, foram alcançados concentrações baixas de glicose ¿ na faixa de 5 g/L ¿ e rendimentos globais de processo em glicose (pré-tratamento e hidrólise enzimática) na faixa dos 6%. Suplementou-se o caldo com glicose sintética para a realização dos ensaios de fermentação alcoólica para a produção de acetona, n-butanol e etanol (ABE). Avaliou-se três modos de operação: (1) fermentação batelada, (2) fermentação batelada com aplicação de vácuo intermitente e (3) fermentação semi-batelada com aplicação de vácuo intermitente (apenas na fermentação etanólica). Para a fermentação etanólica, observou-se que o tempo de reação diminuiu em 3h comparando batelada com batelada mais vácuo intermitente, aumentando a IV produtividade de 2,66 g/Lh para 3,20 g/L.h. Para os ensaios semi-batelada com vácuo intermitente, a produtividade foi inferior (1,74 g/Lh) pois o fornecimento de substrato era inferior a taxa de metabolização, levando a períodos de inatividade do micro-organismos. Este problema, no entanto, pode ser contornado, ministrando-se um substrato mais concentrado ou ultrapassando-se o volume inicial de fermentação. Com relação à fermentação ABE, verificou-se que a metabolização de substrato rico em pentoses ocorre muito lentamente (cerca de 84h totais) com baixas conversões do substrato (cerca de 40%), não justificando uma operação com vácuo. Já a fermentação de substrato com hexoses e pentoses é concluída após 72h de operação em batelada, com produtividade de 0,178 g/Lh de ABE. A aplicação de vácuo no mesmo ensaio aumentou a produtividade do processo para 0,293 g/Lh. Com este trabalho, observou-se que a utilização da tecnologia a vácuo leva ao aumento de produtividade em ambos os processos… Advisors/Committee Members: Mariano, Adriano Pinto, 1978- (advisor), Maciel Filho, Rubens (committee member), Santos, Samantha Christine (committee member).

▼ With an unpredictable market for gasoline and increased concerns with the pollution created by burning fossil fuels, there is a push for developing suitable replacements for gasoline. While corn-based ethanol production is the most common renewable biofuel produced in the United States, ethanol is not an ideal solution to gasoline replacement due to low energy density, hygroscopic and corrosive properties and inability to purify by distillation alone. Higher alcohols such as butanol do not have the same problems with energy density, purification and hygroscopic and corrosive properties. The fermentation of butanol by using solventogenic Clostridium species, creating acetone, butanol and ethanol (known as ABE fermentation) is one of the world’s oldest industrial fermentations. Since butanol is toxic to Clostridium species at a concentration of only 13 g/L, traditional batch fermentation of butanol with steam stripping distillation is currently not as economical as fermentation and distillation of ethanol. Fermentation using glucose produced higher solvent outputs, rates of productivity and yields than fermentations using sugarcane products as substrates. Butanol and total solvent production using glucose as a substrate averaged 7.2 (+/- 0.7) g/L and 11.2 (+/- 0.9) g/L, respectively. Fermentation using sugarcane molasses and sugarcane juice as substrates produced 6.5 g/L butanol and 9.7 g/L total solvents and 3.1 g/L butanol and 4.0 g/L total solvents, respectively. Production of butanol was increased to 9.1 g/L in a fermentation of glucose when soy oil was used as a coextractant. Fermentations in which the pH dropped below 4.80 showed decreased solvent production and the pH was unable to rise in the same manner as other fermentations. The acid crash was exhibited in several batch fermentations as well as continuous fermentation using an immobilized culture of C. beijerinckii optonii. The acid crash resulted in lowered solvent production, low pH and physiological differences in the cells in the culture. Fermentation using immobilized culture produced a maximum 5.4 g/L butanol and 6.8 g/L total solvents at a dilution rate of 0.18 hr-1 and 25 g/L initial glucose. Higher glucose levels and different dilution rates gave lower butanol and total solvent productions.

▼ The cyanobacterium Synechocystis sp. PCC 6803 is an attractive target for engineering novel metabolic pathways for the synthesis of useful compounds directly from CO2 as it is a naturally transformable, oxygenic photoautotroph and the genome has been sequenced. The compound n-butanol is a potential bio-fuel for direct replacement of petroleum, with little to no adjustment of the current infrastructure, as n-butanol has similar fuel characteristics to petroleum. To accomplish the aim, an integrative expression system was developed consisting of two plasmids, which integrated at the phaAB and phaEC loci. Integration at the phaEC site eliminated a competing pathway, polyhydroxybutyrate (PHB) biosynthesis. The two plasmids were used to introduce foreign genes into the genome under the control of promoters PphaA and PphaE. The expression system was validated and analysed using a luciferase reporter enzyme. The promoters were found to express under circadian rhythm, expression was increased in the dark and repressed in the light. In addition, under phosphate limitation the luciferase expression was increased three-fold and became constitutively expressed. Expression was strongly up-regulated in the stationary compared to the logarithmic growth phase. The genes for n-butanol biosynthesis pathway from Clostridium beijerinckii were introduced into Synechocystis sp. PCC 6803 under control of the PphaA and PphaE promoters; however, no butanol could be detected above background levels. Enzyme assays of the cell lysate showed that two of the enzymes activities could not be detected, indicating either the enzymes were inactive or being expressed below limits of detection. Replacement of the C. beijerinckii Bcd-complex with crotonyl-CoA reductase (Ccr) from Streptomyces collonius, along with codon optimisation of the remaining C. beijerinckii genes, generated strain SynRH-10, which synthesised 36 μg/L of culture in eight days and had a peak output of 14 μg/day/L of culture. The aldehyde dehydrogenase enzyme was identified as a potential bottleneck and will require replacement to improve n-butanol output. The program Precog was developed to identify additional novel pathways from MetaCyc reaction and compound data. Several novel pathways were identified, in doing so it also identified Ccr as an additional putative bottleneck in the pathway. An engineering strategy and new pathway was proposed, based on the results of this research and from other studies, which could generate a strain capable of synthesising milligram quantities per litre of culture.

▼ Resumo: Os resíduos agroindustriais são fontes de energia baratas, abundantes e renováveis na Terra que, devido à sua grande disponibilidade e composição orgânica, podem assim, ser reutilizados em processos biológicos como fontes de substratos alternativos e sustentáveis para obtenção de produtos relevantes e com grande poder econômico. Neste sentido, este projeto de pesquisa objetivou avaliar a potencialidade da manipueira, resíduo resultante do processamento industrial da mandioca, para produção de produtos de interesse industrial e comercial. Na primeira etapa, utilizou-se uma cultura mista de microrganismos anaeróbios tratada termicamente para produção de ácidos orgânicos voláteis (AOVs) e, posteriormente utilizou-se uma cultura de Clostridium acetobutylicum ATCC 824 para conversão dos ácidos AOVs butanol. Essa etapa experimental foi realizada em reatores de batelada em sistema bifásicos, acidogênico e solventogênico separados fisicamente, utilizando a técnica do Planejamento Experimental por Delineamento de Composto Central Rotacional (DCCR) (22) para avaliar o efeito do pH (4,5¿7,0) e da concentração de substrato (10¿50 g/L) sobre a produção. Foram obtidos concentrações de ácido lático de 40 g L-1 com cultura mista e 33 g/L com C. acetobutylicum. Na segunda etapa, avaliou-se o comportamento da cultura de C. acetobutylicum DSMZ 792 e da cultura mista em meio sintético contendo 30 g/L glicose. A fermentação nessa etapa resultou numa concentração de 5,88±1,88 g/L de ácido lático com a cultura mista e 3,91±1,34 g/L com a cultura de C. acetobutylicum DSMZ 792. Na terceira etapa, avaliou-se o comportamento da cultura de C. acetobutylicum DSMZ 792 em diferentes fontes de substratos, glicose, manipueira, manipueira suplementada com fécula de mandioca e somente fécula de mandioca, com concentração inicial de 20 g/L para cada substrato, em termos de glicose. Os principais metabólitos quantificados foram: ácido lático, acético e butírico. As máximas concentrações verificadas nos diferentes ensaios foram: ensaios com glicose: 1,72±0,63; 2,24±0,23 e 2,85±1,08 g/L de ácido lático, acético e butírico, respectivamente. Com a manipueira resultou 10,10±2,55; 1,69±0,10 e 0,06±0,16 g/L de ácido lático, acético e butírico. Nos ensaios com manipueira suplementada com fécula de mandioca resultou na produção de 7,87±1,59; 1,64±0,13 e 0,10±0,27 g/L de ácido lático, acético e butírico. E nos ensaios com somente fécula de mandioca as principais concentrações observadas foram: 0,74±0,58; 1,68±0,14 e 1,09±0,83 g/L de ácido lático, acético e butírico. Neste ensaio foi possível a quantificação de butanol, porém em baixa concentração. E finalmente, na quarta etapa utilizando a técnica do DCCR, avaliou-se o comportamento do C. acetobutylicum DSMZ 792, utilizando de fécula de mandioca, como substrato orgânico em diferentes faixas de pH (4,5-7,0) e concentração de substrato (10-50 g/L). Com relação aos resultados obtidos, observou-se concentrações inferior a 0,5 g/L de ácido lático em ambos ensaios. Os ensaios com concentração inicial de 15,8… Advisors/Committee Members: Silva, Ariovaldo José da, 1966- (advisor), Fernandes, Bruna Soares (advisor), Zaiat, Marcelo (committee member), Moraes, Bruna de Souza (committee member), Peixoto, Guilherme (committee member), Mariano, Adriano Pinto (committee member).

▼ With growing concerns over emissions, homogeneous charge compression ignition (HCCI) engines offer a promising solution through reducing NOx and particulate emissions and increasing efficiency. However, this technology is not without its challenges and numerical modeling of these engines can offer some insight into addressing these challenges. This study uses domain decomposition with FORTRAN MPI to subdivide computationally intensive sections of a 10 zone simulation model. Using an Intel i7 quadcore workstation the parallelized model reduced runtimes by half compared to serial computations. From here, two sets of biofuel experimental data were used to improve the validation base of the model. The fuels used were a simulated biomass derived gas (consisting of H2, CH4, CO, CO2, and N2) and a butanol/n-heptane blend. Once calibrated, the model showed good pressure, heat release, and products of incomplete combustion prediction for biogas. NOx emissions were high, however the overall trend was captured. Similarly, once calibrated to the butanol/n-heptane data to account for some of the effects of negative valve overlap (NVO), excellent pressure and heat release predictions were obtained. However, products of incomplete combustion and NOx were low and this was attributed to the inability of the model to properly account for inhomogeneity and all the effects of NVO. Once again though, the overall trend in NOx levels was captured by the model. It was also found that the model does not operate very well near the misfire limit of the engine as it cannot capture the cyclic variability that can occur here. Based on the two new validation cases, it is concluded that once calibrated, the model can be used as a predictive tool for pressure, heat release, and combustion phasing of biofuelled HCCI engines. Furthermore, to improve its predictive capabilities, it is recommended that the model be restructured to incorporate mass transfer between zones, a fixed crevice volume and variable thermal boundary layer, and a CFD solver to improve emissions predictions and reduce reliance on calibration. Finally, changing the zone distribution from ring like zones to lumped stirred reactors is recommended to allow for more realistic modeling of actual experimental HCCI conditions.
