▼ Bacteria can produce power in microbial fuel cells (MFCs) by converting organic matter into electricity. As an added benefit, the organic matter used in the system can come from waste streams that would need to be treated, often by energy consuming processes. There are several studies investigating power production from pure culture communities as well as studies using mixed cultures for power production, but very few studies actually comparing power production from both mixed culture and pure culture communities. The dissimilatory metal reducing bacterium (DMRB) Shewanella oneidensis MR-1 has been used as a model bacterium in MFC studies, but there may be a bacterium (or consortia of bacteria) that is better suited for power production in MFCs. In this study, power densities from undefined mixed cultures obtained from a wastewater treatment facility, as well as from a pure culture of the facultative anaerobe S. oneidensis MR-1, were compared in cube shaped, 1-bottle, 2-bottle, and 3-bottle batch-fed MFC reactor configurations. Results show that the mixed culture produced 68 to 480% more power than S. oneidensis MR-1 in MFCs. The mixed culture produced the maximum power density of 858±9 mW m-2, while the MR-1 culture produced a maximum of 332±21 mW m-2 in a 1-bottle MFC. The difference in power production was the result of the decreased internal resistance in the mixed culture MFC compared to the internal resistance obtained with the MR-1 anode community. Oxidation-reduction potentials (ORP) were measured to help analyze the environmental conditions within the MFCs during power production. The results show that the environment that the bacteria are subjected to in the anode chamber can fluctuate from a reductive to an oxidative environment during the batch cycle. Power production decreased as the redox environment became more positive at the end of each cycle. However, the mixed culture MFCs produced more power than the MR-1 MFCs even though the redox environment was less negative. Considering this significant difference in power production as well as the limitations of substrate oxidation encountered by MR-1, there may be microorganisms that are more important for power production than S. oneidensis MR-1.

▼ Microbial fuel cells (MFCs) have been shown to simultaneously treat wastewater and generate electricity. Scaling up MFCs will require compact and efficient reactor designs, stable performance, inexpensive electrode materials, and high power production using domestic wastewater. In this study, small graphite fiber brush anodes were used in larger-scale MFCs to determine if stable anode potentials and high power production could be achieved when using domestic wastewater in fed batch and continuous flow modes. Additionally, a new activated carbon cathode material incorporating nitrogen and phosphorus was tested in cube MFCs to determine if power generation would be higher compared to other activated carbon cathode materials when using a phase inversion process to produce these cathodes. Small diameter graphite brush anodes were examined using three different cathode configurations: a platinum catalyst on carbon cloth without a separator (Pt-NS); a platinum catalyst on carbon cloth with polyvinyl alcohol (PVA) (Pt-PVA) separator; and an activated carbon cathode with cloth separator (AC-CS). The Pt-NS and Pt-PVA configurations achieved similar maximum power densities in batch mode, but the Pt-NS had a lower maximum power density in continuous flow mode. Long-term operation using wastewater and the Pt-NS cathode resulted in erratic anode performance based on power generation in continuous flow mode, likely as a result of oxygen contamination of the anodes. The use of a PVA separator to reduce oxygen crossover into the anode chamber did not stabilize performance. An AC-CS cathode was then examined as a method to restore anode performance, but this cathode produced only half the maximum power density obtained with the Pt-NS or Pt-PVA MFCS operated in fed batch mode. It was hypothesized that the poor stability in performance of the MFC was due to low wastewater strength. Therefore, the wastewater was amended with 1 g/L sodium acetate and operated using the AC-CS cathode in continuous flow mode. The use of the acetate amended wastewater resulted in stable operation and reproducible performance between replicate reactors. The anodes had a high negative potential and polarization data did not show signs of power overshoot. This indicates that the graphite fiber brush anodes will perform better under high COD conditions. An alternative cathode material was examined in separate tests using smaller cube type MFCs to determine if incorporating nitrogen and phosphorus into the activated carbon material would improve performance, as reported by others by a press process, when cathodes were instead constructed using a phase inversion process. After immersing cellulose in an ammonium phosphate solution, allowing it to air dry, and then heating in a nitrogen atmosphere at 5°C/min to 900°C, this material was then used to make a cathode by a phase inversion process. The power performance achieved with this dual doped cellulose-derived activated carbon cathode (cellulose N+P) was compared to a plain, self-manufactured cellulose activated…

▼ Exoelectrogens are distinct microbial species possessing the ability to transfer electrons from the organic substrates (respiration) to solid electron acceptors such as Fe (III) and Mn (IV) minerals. Even though, the existence of such a respiratory pathway in microbes was speculatively linked by the environmental microbiologists to the phenomenon of origin of life in oxygen free mineral rich conditions on earth, it is however not until the recent developments in microbial fuel cell (MFC) technology that the respiratory phenomenon/mechanism was fully understood. The thesis initially explores the exoelectrogenic microbial communities in waste water treatment plant samples obtained following anaerobic (digestate) and aerobic (activated sludge) treatments through a MFC based inoculation study, wherein microbial communities colonizing the electrode was characterized both by culture independent (community analysis) and culture dependent (isolation) techniques. The community analysis study reveals the presence of bacterial species predominantly within in the genera of Alcaligenes, Lysinibascillus, Arcobacter and Comomonas. Except for Comomonas, species within the other three genera were not isolated via the culture dependent technique. Instead, the culture dependent technique afforded isolation of species within the genera of Enterobacter, Pseudomonas and Aeromonas species. Proteus hauseri DSM 14437T and Klebsiella michiganensis W14T are the two Enterobacter species isolated from the anode. The pseudomonas species that were isolated were Pseudomonas plecoglossicida FPC951T and Pseudomonas hunanensis LVT. The Comomonas species that was isolated was not identified at the species level and were only identified as polyphosphate accumulating bacteria. It is noteworthy to mention that nearly all the species identified both by culture dependent and culture independent techniques present novel observation to the existing literature in exoelectrogenic bacterial species. Following the initial characterization and isolation of exoelectrogens, the thesis explores the mechanism of electron transfer to electrodes in isolated exoelectrogens (culture dependant). Cyclic voltammetry, polarization and media replenishment studies reveal the presence of enzymatic direct electron transfer (DET) to mediate electron transfer in Klebsiella michiganensis W14T and in Comomonas species. However, it is in Proteus hauseri DSM 14437T that a mediated electron transfer via the secretion of a redox mediator was observed to facilitate electron transfer to electrodes. The observation of mediated electron transfer is unknown for Proteus hauseri DSM 14437T species. However, MET is known to occur in Shewanella oneidensis MR-1, which also falls within the same bacterial class as Proteus hauseri DSM 14437T (γ-proteobacteria).The final part of the thesis explores the identification of the redox mediator secreted by Proteus hauseri DSM 14437T via liquid chromatography (LC) based separation followed by structural characterization via electrochemical (EC), UV-Vis and… Advisors/Committee Members: Justin, Gooding, Chemistry, Faculty of Science, UNSW, Michael, Manefield, Chemical Engineering, Faculty of Engineering, UNSW.

▼ Microbial electrochemical cell systems (MECSs), such as microbial fuel cells (MFCs) and microbial electrolysis cells (MECs), are promising clean and renewable energy sources. MFCs employ exoelectrogenic bacteria to convert organic matter in wastewater into electricity, and biogas (hydrogen, methane) is generated from organic matter by applying electricity in MECs. This emerging technology requires better performance by decreasing the material cost to bring it into practical application. Therefore, the main focuses of this research are fabricating nanomaterial based anode to improve the power production and developing micro devices to analyze real-time performance of MECSs. Physical and electrochemical interactions between microbes and anode are critical to performance. Systematic studies on how different lengths, packing densities, and surface conditions of carbon nanotubes (CNTs) affect MFC power output revealed that long and loosely packed CNTs without any amorphous carbon show the highest power production performance. Furthermore, fabricated 3D sponges composed of interconnected CNTs showed better performance compared to commercially available carbon felt anode. Due to the configuration, monitoring of biofilm development is hard in macro-sized MFCs. Microfluidic laminar flow MFC with interdigitated anode was fabricated to monitor the real-time optical and electrochemical activity of Shewanella oneidensis MR-1 in situ. Power density and impedance were measured to understand the relation between biofilm development and power production of biofilm over time. Expensive and labor intensive equipment such as gas chromatography is commonly used to analyze the biogas produced in MECs. A ZnO nanowires based gas sensor was fabricated to measure H2 concentration in real-time without using any other expensive equipment. Low power and low voltage output of MFCs do not allow them to power most electrical applications. Proposed power management systems (PMSs) can overcome this limitation by boosting the MFC output voltage and managing the power for maximum efficiency, regardless of the power and voltage fluctuations from MFCs over time. Overall, the limitations of the MECSs technology have been identified and possible solutions have been proposed to improve the overall performance of this sustainable renewable energy source.

▼ Cellulose dark fermentation is a sustainable method for bio-hydrogen production, but much energy is leftover from the process effluent as soluble fermentation endproducts. Microbial fuel cells are systems where fermentation endproducts or other organic and inorganic sources are oxidized by exoelectrogenic microbes to produce electricity with concurrent water purification. MFCs have been used effectively with a variety of substrates, but few studies have examined the stability of these systems over long periods of operation. It is shown here that MFC reactors—except those fed formic acid—still produced high power densities after one year of operation, but that these power densities decreased over time due to cathode deterioration. The degree of this loss in power density was specific to the electron donor, with the greatest power loss (54.3%) occurring in ethanol fed MFCs. The presence of a cathodic biofilm increased Coulombic efficiencies, but decreased power densities in MFCs fed fermentation endproducts. Microbial electrolysis cells (MECs) utilize exoelectrogenic microbes for the oxidation of organic and inorganic substrates. Unlike MFCs, MECs require a small applied voltage to enable hydrogen evolution at the MEC cathode. MECs have also been shown to be effective with various substrates, but most studies still use platinum catalyst cathodes and very small reactors (<100 mL). It is shown here that a 2.5 L continuous flow microbial electrolysis cell produced a current density of 1.18 A/m2 and a maximum volumetric hydrogen production rate of 0.53 m3/m3/d without precious metal cathodes. The current density of 1.18 A/m2 is slightly lower than might be expected based on other studies, and may be due to increased electrode spacing and the presence of electrode separators. This study provides further evidence that minimizing electrode spacing is likely the most important factor in achieving high current. The continuous flow reactor was shown to be especially prone to methane production as gas produced after 15 days of operation was greater than 90% methane. This rapid transition to nearly complete methane production was likely due to a lack of periodic air exposure during continuous flow operation. Several approaches have been suggested in literature to reduce methane production in MECs. It is shown here that beyond an applied voltage of ~0.6 V, MEC methane production was not dependent on applied voltage or hydrogen production rate, as methane production rates stayed approximately constant above this applied voltage. An increase in temperature from 20 °C to 30 °C increased hydrogen and methane production approximately equally. Reactor air exposure over one day as well as a high applied voltage to the stainless steel cathode did not reduce methane production. In MFC tests, power density was hindered by a low pH solution. The combination of a low pH solution and a steel cathode in MEC operation almost prevented gas production completely. Long-term addition of a 2-Bromoethanesulfonic acid—a known chemical methanogenesis…

▼ ABSTRACT A microbial fuel cell (MFC) is a device that uses bacteria as a biocatalyst to directly convert organic matter into electricity. It provides a promising method for producing sustainable bio-energy as well as simultaneously degrading organic waste and wastewater. Corn stover is currently the largest residual biomass source in the US, and it therefore has a great potential as a sustainable and renewable energy source. Two corn stover hydrolysates (acid and neutral) were demonstrated here to produce electricity in single-chambered air-cathode MFCs, with a maximum power density of 371 mW/m2 for neutral hydrolysate and 367 mW/m2 for acidic hydrolysate. All sugar (monomeric or oligomeric) components were utilized, resulting in ~93% BOD removal efficiency and 20 to 30% of Coulombic efficiency (CE). After applying a diffusion layer onto the cathode surface and increasing the medium conductivity from 10 to 20 mS/cm, the power density could be further improved to 933 mW/m2 (neutral ydrolysate) or 971 mW/m2 (acidic hydrolysate). Microorganisms capable of transferring electrons outside the cell to insoluble electron acceptors, such as metal oxides and the anodes of MFCs, are called exoelectrogens. Very few exoelectrogens have been directly isolated from MFCs, and most exoelectrogens known to produce power in an MFC are dissimilatory metal reducing bacteria (DMRB, e.g. Shewanella and Geobacter) initially isolated using agar plates containing metals. However, isolation methods based on dissimilatory metal reduction potentially limit the diversity of possible exoelectrogenic bacteria. A special U tube-shaped MFC was therefore developed to enrich exoelectrogenic bacteria based on electricity production, with isolation based on dilution-to-extinction methods. A pure culture was obtained and identified as Ochrobactrum anthropi YZ-1 that was unable to respire using hydrous Fe(III) oxide but produced 89 mW/m2 using acetate as the electron donor in the U-tube MFC, demonstrating a greater diversity of exoelectrogenic bacteria than simply DMRBs. Strain YZ-1 used a much wider range of substrates as carbon sources for current production than many DMRBs, including acetate, lactate, propionate, butyrate, glucose, sucrose, cellobiose, glycerol, and ethanol. To use MFC-based technologies for real applications in waste and wastewater treatment processes, one of the greatest challenges is creating a scalable architecture that provides large surface areas for oxygen reduction at the cathode and bacterial growth on the anode. A scalable cathode was therefore constructed by coating a tubular ultrafiltration membrane with conductive graphite paint and a non-precious metal catalyst (CoTMPP). Using a graphite brush anode with high surface area (Aan,s=7700 m2/m3) and two tube cathodes placed inside the reactor (Acat,s= 93 m2/m3), the MFC produced 18 W/m3 with a CE = 70 - 74%. Further increases in the surface area of the tube cathodes to 54 cm2 (120 m2/m3) increased the total power output (from 0.51 to 0.83 mW), but the increase in volume…

▼ Due to environmental concerns associated with fossil fuel mitigation and political volatility of oil-producing countries, and more recently with the advent of rising fuel costs, biomass energy sources have become of great interest. One of the newest ways in which to harness the energy in biomass is through the use of a microbial fuel cell (MFC). MFCs are a new technology with promising application in the field of wastewater treatment amongst many others. MFC research has focused primarily on the treatment of easily degradable soluble carbon sources, but biomass is known for its recalcitrance, and MFC treatment of particulate substrates should be explored more in depth for the best method of treatment. In previous testing of cellulose conversion to electricity in an MFC, hydrolytic and fermentative bacteria have been found to predominately reside near the suspended cellulose that they are degrading, and not on the anode of the MFC. Therefore, one of the methods to keep those organisms within a batch-fed system would be to carry over some of the substrate from the previous cycle into the next. In this study, air-cathode single-chamber bottle MFCs were used to evaluate the ability of both sludge and binary (Geobacter sulfurreducens and Clostridium cellulolyticum) inocula to degrade cellulose, remove COD, and generate power, comparing for each inoculum a system that had carryover from the previous cycle and a system with no carryover. The sludge-inoculated MFCs proved to be superior in the generation of maximum power (41.4 mW/m2 and 39.0 mW/m2 without and with carryover, respectively) to the binary-inoculated MFCs (19.4 mW/m2 and 13.7 mW/m2 without and with carryover, respectively). Higher transient values were seen in the earlier cycles (62 mW/m2 and 44 mW/m2 for sludge-inoculated MFCs without and with carryover, respectively and 28 mW/m2 and 19 mW/m2 for binary MFCs without and with carryover, respectively), but the performance generally appeared to be more stable at the later cycles. Gas composition for the sludge MFCs was monitored and methane was discovered in the headspace of only the system with carryover. For both inocula, the MFCs with carryover demonstrated the highest removal of cellulose (95% for the sludge-inoculated MFC and 90% for the binary MFC). Although carryover did promote higher fermentation rates, this operational strategy also created a system with acidity issues, needing the pH adjusted almost every other day to obtain pH > 6. The highest coulombic efficiency (CE) was observed in the binary MFC with no carryover (11.4%). The rest of the MFCs had CEs of ~ 3%. Acetate was found in abundance in the binary MFC with carryover both before (1.7 mM) and after (10.1 mM) the analyzed run, but not in any other MFCs. This residual acetate concentration suggests that the G. sulfurreducens population was not able to keep up with the fermenters. Real-time PCR with samples from the binary reactors showed that carryover was effective at retaining many more fermentative organisms than the MFC without carryover,…

▼ Microbial fuel cells (MFCs) are emerging energy production technology which converts the chemical energy stored in biologically degradable compounds to electricity at high efficiencies. Microbial fuel cells have some advantages such as use of an inexpensive catalyst, operate under mild reaction conditions (i.e. ambient temperature, normal pressure and neutral pH), and generate power from a wide range and cheap raw materials. These make microbial fuel cell as an attractive alternative over other electricity generating devices. However, so far the major problem posses by this technology is the low power outputs of the microbial fuel cells that hinder its commercialization. Restriction in the electron transfer from bacteria to the anode electrode of a MFC is thought to be one cause for the low power output. Most recent MFC research is focused on using contaminants present in industrial, agricultural, and municipal wastewater as the energy source, with very few studies utilising gaseous substrates. Mediators can be added to MFCs to enhance the electron transfer from the microbe to the anode, but have limited practical applicability in wastewater applications because of the difficulty in recovering the expensive and potentially toxic compound. This thesis describes an investigation of electricity generation in a microbial fuel cell by combining a gaseous substrate with a mediator in the anode compartment. The emphasis being placed on the selection of a mediator to improve the electron transfer process for electricity production in an MFC. Subsequently, methods to improve the performance of a mediator MFC in respect of power and current density were discussed. This type of MFC is purposely aimed to be applied for treating gaseous contaminants in an anaerobic biofilter while simultaneously produce electricity. In this study, ethanol was the first gaseous substrate tested for the possibility to generate electricity in the MFC. Various mediators were previously compared in their reversibility of redox reactions and in the current production, and three best mediators were then selected for the power production. The highest electrical current production i.e. 12 μA/cm2 was obtained and sustained for 24 hrs with N,N,N',N'-tetramethyl-1,4- phenylendiamine TMPD (N-TMPD) as the mediator using glassy carbon (GC) electrode. The maximum power density reached 0.16 mW/cm2 by using carbon cloth (CC) anode. The absorption of these mediators by the bacterial cells was shown to correlate with the obtained energy production, with no N-TMPD was absorbed by the bacterial cells. The 24 hr current production was shown to be accompanied by the decrease in the ethanol concentration (i.e. 1.82 g/L), however ethanol crossover through the proton exchange membrane and ethanol evaporation around the electrodes were most likely to be the major cause of…

▼ Canada has the third largest oil reserves in the world. Close to 96% of these reserves are located in oil sands deposits (CAPP, 2015). Extraction of bitumen from these oil sands is carried out by alkaline hot water process (Clark Process) which results in the generation of large volumes of waters contaminated with naphthenic acids (NAs). These waters are referred to as Oil Sands Process Water (OSPW) and they are maintained in large tailing ponds due to their toxicity and a zero-discharge policy enforced by the Government. Given the environmental challenges associated with OSPW and tailing ponds, several physicochemical and biological treatments have been evaluated as remediation option. Previous studies in our research group have successfully achieved biodegradation of model NAs in conventional bioreactors of various configurations under aerobic and anoxic conditions (Paslawski et al., 2009; Huang et al., 2012; D’Souza et al., 2014; Gunawan et al., 2014; Dong and Nemati, 2016). Against this background, the current work offer an alternative treatment approach based on anoxic biodegradation of NAs in Microbial Fuel Cells (MFCs). MFCs are unconventional bioreactor in which biodegradation of a contaminant occurs with concomitant generation of energy. In the present study, biodegradations of a linear (octanoic acid) and a cyclic NA (trans-4-methyl-1-cyclohexane carboxylic acid, trans-4MCHCA) were evaluated in MFCs. Firstly, biodegradation of individual NAs (100, 250 and 500 mg L-1) was carried out in batch operated MFCs with either graphite rod or granular graphite electrodes. Maximum biodegradation rates in the single rod electrode MFCs were achieved during the biodegradation of NAs with highest concentration (1.56 and 2.46 mg L-1 h-1 for trans-4MCHCA and octanoic acid, respectively). This trend was also observed in MFCs with granular electrodes, where the removal of 500 mg L-1 of each individual compound led to the highest biodegradation rates, with values of 7.2 and 22.78 mg L-1 h-1 for trans-4MCHCA and octanoic acid, respectively. Regardless of the type of employed electrodes, biodegradation of the linear NA occurred at a rate much faster than that of its cyclic counterpart. Moreover, sequential batch operation of MFCs enhanced the biodegradation rate of both compounds. In continuously operated MFCs with granular electrodes, biodegradation of each individual NAs (trans-4MCHCA or octanoic acid) was assessed at initial concentrations of 100, 250 and 500 mg L-1, with the maximum biodegradation rate again achieved with the highest NA concentration (36.5 and 49.9 mg L-1 h-1 for trans-4MCHCA and octanoic acid, respectively). Interestingly, the highest current and power densities were attained when the biodegradation rate was at the level, with the values being 481.5 mW m-3 and 4296.3 mA m-3 for trans-4MCHCA, and 963.0 mW m-3 and 6000.0 mA m-3 for octanoic acid. Co-biodegradation of linear and cyclic NAs was also studied using mixtures of NAs with different concentrations in two MFC configurations: batch-wise operated with… Advisors/Committee Members: Nemati, Mehdi, Evitts, Richard, Zhang, Lifeng, Kerry, McPhedran.

Une pile à combustible microbiennes (PCM) est un dispositif capable de produire de l’énergie électrique à partir d’énergie chimique grâce à l’activité catalytique des bactéries en présence de combustibles organiques. Ces travaux de thèse ont eu pour objectif la synthèse des nouveaux matériaux d’anode et de cathode qui pourraient constituer des alternatives aux matériaux à base de platine. Coté anode, nous avons synthétisé des matériaux par précipitation chimique sur du graphite en poudre à partir de mélanges contenant des ions ferreux et sulfures. Les caractérisations physicochimiques ont montré la formation de composés soufrés (mackinawite, polysulfures et soufre élémentaire) qui se transforment en produits soufrés plus oxydés en présence d’air. La formation de vivianite a été confirmée dans le cas d’un excès d’ions ferreux par rapport aux ions sulfures. Les analyses électrochimiques montrent que ces matériaux ont un comportement réversible avec des densités de courant d’oxydation élevées à bas potentiel. Coté cathode, nous avons choisi la synthèse par voie électrochimique d’un film de MnOx sur substrat d’acier inoxydable. Les caractérisations physicochimiques ont démontré la formation de la birnessite. Les analyses électrochimiques montrent que la réduction de ce matériau conduit à des courants cathodiques significatifs mais avec une réversibilité limitée, même en présence d’air. La réalisation de prototypes de PCM dans lesquels l’anode à base de composés soufrés est immergée dans une solution de terreau et la cathode à base de MnOx est au contact de l’air, a permis d’obtenir des puissances instantanées maximales de l’ordre de 12 W.m-3 et 1,8 W.m-2, et des densités de courant de l’ordre de 25 A.m-3 et 3,8 A.m-2. Un travail d’optimisation du fonctionnement de PCM a été réalisé. Ainsi, l’augmentation de la conductivité de la solution anodique et la diminution de quantité de sédiment dans la solution de terreau a permis d’améliorer la réponse électrochimique du matériau anodique et d’obtenir des puissances instantanées maximales de l’ordre de 17,5 W.m-3 et 2,7 W.m-2, et des densités de courant de l’ordre de 60 A.m-3 et 9,2 A.m-2. Le facteur limitant reste toujours le comportement électrochimique du film de MnOx.

A microbial fuel cell (MFC) is a device allowing the production of electric power from chemical energy thanks to the catalytic activity of bacteria in presence of organic fuel. These works aimed the synthesis of new anode and cathode materials which could be an alternative to platinum materials. On the anode side, we synthesized the materials by chemical precipitation on powder graphite from mixtures containing ferrous and sulfide ions. Physicochemical characterizations showed the formation of sulfur compounds (mackinawite, polysulfide and elementary sulfur) which transform into sulfur products more oxidized in presence of air. Formation of vivianite was confirmed in the case of an excess of ferrous ions in relation to sulfide ions. Electrochemical analysis shows that these materials have a reversible…

▼ Microfluidics and micro/nanofabrication techniques provide powerful technological platforms to develop miniature bioassay devices for studying cellular and multicellular organisms. Microfluidic devices have many advantages over traditional counterparts, including good throughput due to parallel experiments, low infrastructural cost, fast reaction, reduced consumption of agent and reagent, and avoidance of contamination. This thesis is focused on the development of a microfluidic toolkit with several miniature devices to tackle important problems that the fields of plant phenotyping and bioenergy harvesting are facing. The ultimate goal of this research is to realize high-throughput screening methods for studying environment-genomics of plants through phenomics, and understanding microbial and plant metabolisms that contribute to harvesting bioenergy from microbes and living plants in different environments. First, we develop vertical microfluidic plant chips and miniature greenhouses for high throughput phenotyping of Arabidopsis plants. The vertical design allows for gravitropic growth of multiple plants and continuous monitoring of seed germination and plant development at both the whole-plant and cellular levels. An automatic seed trapping method is developed to facilitate seed loading process. Also, electrospun nanofibrous membranes are incorporated with a seed germination chip to obtain a set of incubation temperatures on the device. Furthermore, miniature greenhouses are designed to house the plant and seed chips and to flexibly change temperature and light conditions for high-throughput plant phenotyping on a multi-scale level. Second, to screen bacteria and mutants for elucidating mechanisms of electricity generation, we develop two types of miniature microbial fuel cells (µMFCs) using conductive poly(3,4-ethylenedioxythiophene) nanofibers and porous graphene foam (GF) as three-dimensional (3D) anode materials. It is demonstrated that in the nanofiber-based µMFC, the nanofibers are suitable for rapid electron transfer and Shewanella oneidensis can fully colonize the interior region of the nanofibers. The GF-based µMFC is featured with a porous anolyte chamber formed by embedding a GF anode inside a microchannel. The interconnected pores of the GF provide 3D scaffolds favorable for cell attachment, inoculation and colonization, and more importantly, allow flowing nutritional and bacterial media throughout the anode with minimal waste. Therefore, the nutrients in bio-convertible substrates can be efficiently used by microbes for sustainable production of electrons. Last, we develop a first miniature plant-MFC or µPMFC device as a technological interface to study bioenergy harvesting from microbes and living plants. A pilot research is conducted to create the µPMFC device by sandwiching a hydrophilic semi-permeable membrane between a µMFC and a plant growth chamber. Mass transport of carbon-containing organic exudates from the plant roots to the µMFC is quantified. This work represents an important step towards…

▼ Toxic pollutants such as phenols and dyes in industrial wastewater have raised increasing environmental and human health concerns in many industrialized countries around the world. There is an ongoing need to develop sustainable and cost-effective technologies to remove these pollutants. Bioelectrochemical technology such as microbial fuel cell (MFC) system has been approved as promising and sustainable treatment process for removing of these organic toxic pollutants, while generating electricity by exoelectrogenic bacteria. The exceptional MFC ability to degrade chlorophenol as one of the recalcitrant pollutants in industrial wastewater has been explored in this study. Three functional bacteria: pure culture Bacillus subtilis, and two mixed microbial consortia derived from domestic and industrial petrochemical wastewaters have been utilized for electricity generation and 2,4-dichlorophenol (2,4-DCP) degradation in a double chamber MFC system. The selection of microorganisms is based on their ability to degrade phenols and its derivatives so as to discover good exoelectrogenic bacteria to drive MFC system for degradation of 2,4-DCP and production of electricity. The industrial petrochemical wastewater as a highly phenolic-contaminated wastewater is expected to provide its mixed consortium better acclimatization in 2,4-DCP-mediated MFC environment as compared to typical mixed consortium from domestic wastewater. Bacillus subtilis has been approved to show its great ability to generate maximum current density of 64 mA/m² in persulfate-based catholyte MFC system while degrading up to 60% of 2,4-DCP. Chemical properties of catholytes, for instance, oxidizing and buffering abilities, could improve the MFC performance through well controlled pH and electron transfer mechanism. The experimental results revealed that low-cost and low-toxicity catholytes, such as potassium persulfate, M9 and phosphate buffer could amplify the electricity generation with simultaneous 2,4-DCP degradation in double chamber MFC system. Like B. subtilis, mixed consortia from both domestic and industrial wastewaters have demonstrated high performance in electricity generation and 2,4-DCP degradation using Pt/Ti electrode in MFC systems. The important bacteria in domestic mixed consortium for 2,4-DCP degradation have been identified as Arcobacter and Cloacibacterium which showed positive response towards the toxic pollutants in anodic MFC. Industrial mixed consortium in which Bacillus dominated the cultures, performed well in generating 156 current density, with 41% phenolic degradation as compared to domestic consortium with 123 mA/m² and 62% phenolic degradation. This study proved that Bacillus sp. from petrochemical wastewater could have high adaptation in chlorophenol containing medium through its high current generation profiles in MFC despite of its relatively low 2,4-DCP degradation capability. The performance of both mixed consortia was further investigated for its growth kinetics and 2,4-DCP biodegradation pathways in double chamber MFC… Advisors/Committee Members: Jin, Bo (advisor), School of Chemical Engineering (school).

▼ Biofuel cell (BFC) is an emerging renewable technology that can perform high direct energy conversion efficiency to electricity. BFC system uses low energy density sources, such as organics in wastewater and converts them into electricity. The system is based on biological catalysts such as microorganisms and enzymes, which are capable of consuming the organics in the sewage for metabolism. In the process, the BFC system will convert the organics in the wastewater and reduce the biological oxygen demand of the sewage to a safe level before it is released to the environment. Nevertheless, commercialisation of BFC applications are still a long way to go due to many weaknesses that have to be overcome. Culturing exoelectrogenic bacteria and applying new materials to enhance catalytic process in microbial fuel cell (MFC) are some of the options to improve MFC operation. The aims of this study are two-fold: To develop (i) a MFC for electricity generation from wastewater by bacteria isolated from a trickling filter, and (ii) an enzymatic fuel cell (EFC) for continuous measurement of lactose concentration in dairy wastewater as well as electricity generation. This thesis shows that the multi-cultured bacteria could generate electricity after 30 days exposure to oxygen at a concentration of 7.5 ppm and that the fabricated graphite-epoxy composite anodes possess the desired characteristics of a good electrode. Such fabricated electrodes can be prepared within a very short time-span compared to commercial electrodes. These electrodes are cheap and flexible for surface modification. However, due to inherent high resistance of the graphite-epoxy composite, it was unable to generate as much current intensity as commercial material electrodes. This study has highlighted several areas that can be further explored such as reducing inherent resistance in graphite composite electrode and the potential use of combined multi-walled carbon nanotube (MWCNT)-diazonium salt within graphite matrix as a reusable high performance electrode.

▼ Microbial fuel cells (MFCs) and related technologies (bioelectrochemical systems, BESs) use microbes as catalysts for reactions that donate electrons to or use electrons from a circuit. At the anode, exoelectrogens oxidize organic matter and donate electrons to the electrode. At the cathode, electrotrophs consume electrons for their metabolic needs. BESs have potential for a number of practical purposes, from generating useful fuels such as hydrogen and methane to generating electricity while treating wastewater. The work described here addresses some of the issues in understanding microbial communities in these systems and in improving the functionality of BESs. Hydrogen and Methane from Swine Wastewater. The production of a useful and valuable product during swine wastewater treatment, such as hydrogen gas, could help to lower treatment costs. Hydrogen can theoretically be produced from wastewater by electrohydrogenesis in a microbial electrolysis cell (MEC) or by fermentation. Using a single-chamber MEC with a graphite-fiber brush anode, hydrogen gas was generated at 0.9-1.0 m3-H2 m-3 day-1 using full-strength or diluted swine wastewater. COD removals ranged from 8-29% in 20-h tests, and from 69-75% in longer tests (184 hours) using full-strength wastewater. The gas produced was up to 77 ± 11% hydrogen, with overall recoveries of up to 28 ± 6% of the COD in the wastewater as hydrogen gas. Methane was also produced at a maximum of 13 ± 4% of total gas volume. The efficiency of hydrogen production, based on the electrical energy needed (but excluding the energy in the wastewater) compared to the energy of the hydrogen gas produced, was as high as 190 ± 39% in 42-h batch tests with undiluted wastewater, but was lower in longer batch tests of 184 hours (91 ± 6%). Hydrogen gas could not be recovered in fermentation tests using wastewater with a heat-treated inoculum. Hydrogen production was shown to be possible by fermentation when the wastewater was sterilized, but this process would not be practical or energy efficient. We therefore conclude from these tests that MECs are an effective method for hydrogen recovery from swine wastewater treatment, although the process needs to be further evaluated for reducing methane production, increasing the efficiency of converting the organic matter into current, and increasing recovery of hydrogen gas produced at the cathode. Optimal Set Anode Potentials Vary in Bioelectrochemical Systems. In BESs, the anode potential can be set to a fixed voltage using a potentiostat but there is no accepted method for defining an optimal potential. Microbes can theoretically gain more energy by reducing a terminal electron acceptor with a more positive potential, for example oxygen compared to nitrate. Therefore, more positive anode potentials should allow microbes to gain more energy per electron transferred than a lower potential, but this can only occur if the microbe has metabolic pathways capable of capturing the available energy. This review of the literature shows that there is a general…

▼ Microbial fuel cell (MFC) has become one of the energy-sustainable technologies for wastewater treatment purpose in the recent years. It combines wastewater treatment and electricity generation together so as to achieve energy balance. By inoculating microorganism in the anode chamber and filling catholyte in the cathode chamber, and also with the help of a proton exchange membrane (PEM) between them, the MFC can transfer protons and produce power. Microbial desalination cells (MDC) are based on MFC’s structure and can fulfill desalination function by the addition of a middle chamber and anion exchange membrane (AEM). This study focuses on ammonium removal and electricity generation in MDC system. Mainly two types of liquid were tested, a solution of Hjorthorn Salt and filtrated supernatant. The experiments were performed at Hammarby Sjöstad research station and laboratory of Land and Water Resources department, Stockholm. It consists of a preparation stage, a MFC stage and a MDC stage. Until the end of MFC stage, biofilm in the anode chamber had been formed and matured. After that, solutions of different initial concentrations (1.5, 2.5, 5, 15 g/L) of Hjorthorn Salt and also filtrated supernatant have been tested. Ammonium removal degree can be obtained by measuring the initial concentration and cycle end concentration, while electricity generation ability can be calculated by voltage data which was continuously recorded by a multimeter. Results showed that this MDC system is suitable for ammonium removal in both of Hjorthorn Salt solutions and supernatant. The removal degrees in Hjorthorn Salt solution at desalination chamber were 53.1%, 52.7%, 60.34%, and 27.25% corresponding to initial NH₄₊ concentration of 340.7, 376, 376 and 2220 mg/L. The ammonium removal degrees in the supernatant were up to 53.4% and 43.7% under 21 and 71 hours operation, respectively. In power production aspect, MDC produced maximum voltage when potassium permanganate was used in the cathode chamber (217 mV). The power density in solutions of Hjorthorn Salt was relative low (46.73 - 86.61 mW/m³), but in the supernatant it showed a good performance, up to 227.7 and 190.8 mW/m³.

▼ Microbial fuel cells (MFCs) use bacterial metabolism to harvest the energy content of organic compounds, producing electrons and protons. In recent years, mutation of bacterial strains to increase the power output has emerged as a priority research focus in the field of MFCs. This thesis investigates wild-type Pseudomonas aeruginosa (PAO1) and two of its mutant strains pilT and pilT-bdlA in Luria broth media (LB) to determine the effect of mutation in the performance of MFCs. In addition the PAO1 and pilT strains are tested in the first urine-based MCF employing genetically engineered bacteria. Polarization and electrochemical impedance spectroscopy (EIS) were implemented to observe the performance of MFC reactors with different bacterial strains and media. The pilT mutant has reduced twitching motility and hyperpiliation, both of which enhance the formation of electrogenic biofilms. The double mutant, pilT-bdlA also has chemotaxis suppression, which should lead to more persistent biofilms because the pilT-bdlA strain does not escape the electrode surface even when the nutrient concentration is low. The increase in biofilm thickness due to pilT-bdlA mutation is also expected to increase the power output. In LB media (Chapter 3), polarization data show that the pilT produces a 4.8-fold power enhancement compared to wild-type PAO1 and a 2.3-fold power enhancement over pilT-bdlA. The pilT-bdlA MFC performance was in between pilT and/ PAO1 (pilT > pilT-bdlA > PAO1). That is, the pilT-bdlA double mutation did not display the expected power enhancement. In urine-based MFCs (Chapter 4), the pilT mutant showed a 2.7-fold increase in peak power density compared to the wild-type strain, PAO1. For both strains, the observed high internal resistance near open circuit voltage was traced to sluggish redox reactions on the anode surface and not to bacterial metabolism. The observed performance of the pilT mutant proved that mutant strains can increase the power output, opening new opportunities for urine-based mini-devices.

▼ Microbial fuel cells (MFC) are an emerging renewable technology which converts complex organic matter to electrical power using microorganisms as the biocatalyst. A variety of biological relevant organic matters such as glucose, acetate and ethanol have been utilized for the successful operation of a MFC. In this regard, the investigation of a MFC inoculated with ethanol oxidizing bacteria is of particular interest for this research due to its ability to simultaneously produce electricity while reducing ethanol pollution (a type of volatile organic carbon (VOC) pollutant) with potential use in modified biological air pollution control technology such as biofiltration. In this research, ethanol-oxidizing microbial species isolated from soil and compost samples were identified, with Acinetobacter calcoaceticus being the dominant strain. In order to understand the metabolism of the anode microbial cells, which is considered to be the key dictating the performance of a MFC, a systematic analysis/optimization of the growth rate and biomass production for A. calcoaceticus were carried out. A maximum specific growth rate with a final biomass concentration of 1.68 g/l was derived when aerated at a rate of 0.68 vvm. It has been recognized that one of the principle constraints in increasing the current density of MFCs is the electron transfer from the bacteria to the anode. In this sense, the addition of a redox mediator, which facilitates the process of the electron transfer, is desired for the efficient operation of a MFC. Thionine, methylene blue (MB), resorufin and potassium ferricyanide that have been profusely utilized as effective mediator compounds in many MFC studies, however, specific information on the biomass sorption of these compounds was lacking and therefore were selected for this research. All mediators tested were reduced biologically in A. calcoaceticus inoculated samples as indicated by the color transition from the pigmented oxidized form to the colorless reduced form. Subsequent tests on mediator color removal revealed that physical adsorption by the biomass, aggregation as well as precipitation accounted for a significant portion of the color loss for thionine and MB. It was speculated that the fraction of the initial mediator concentration sequestered, aggregated and/or precipitated no longer contributed to the electron transfer process, resulting in a current production which was proportional to the measurable mediator concentration remained in anode solution. To verify this hypothesis, chronoamperometric measurements were conducted for various mediator systems at known initial and measurable concentrations. The data obtained on the current produced were in good agreement with the theoretical predictions calculated from the actual mediator concentration, suggesting that the current produced depended on the concentration of mediator remaining in solution. Finally, the microbial reduction kinetics and the cytotoxicity of potassium ferricyanide were analyzed. The reduction of potassium ferricyanide…

▼ Microbial fuel cells (MFC) are fuels cells that utilize microorganisms as catalysts for the production of electricity. MFCs have important potential for power generation in remote locations and to complement waste water treatment facilities with waste removal and power generation. In order to achieve these goals, power output needs to be increased as well as an understanding the effect that varying electron donors has on electricity production. In order to move the field forward, the research presented herein utilizes the gamma-proteobacteria Pseudomonas areuginosa in pure culture for electricity production. Most research for MFCs utilizing P. aeruginosa have been run using mix cultures and taking advantage of electron mediators produced by P. aeruginosa to increase power output of MFC. While this tends to improve power density for the MFC, it prevents studies that elucidate the effects of individual species. These studies utilized P. aeruginosa as the sole biological catalyst to oxidize organic substrates and produce electrical power. A two-chamber H-style MFC constructed from polypropylene bottles and using a 1 mil Nafion® membrane was utilized for these experiments. Using this setup, several issues were investigated including the effect of the growth substrates glucose, formate, succinate, lactose, and cellobiose on cell growth and electricity production and the effect of glucose and succinate concentration on cell growth and electricity production. It was found that P. aeruginosa is capable of oxidizing glucose and succinate to generate electricity. When using glucose as electron donor, the maximum power density was 46 mW/m2 with the current of approximately 0.35mA – 0.45mA (peak value 0.7 mA) and the electrical potential of approximately 0.05 to 0.15 V. When using succinate as electron donor, the power density was nearly 40.6 mW/m2 with current of 0.39-0.41mA and the electrical potential of approximately 0.1-0.13 V. The most suitable substrates for growth and electricity production were glucose and succinate; which are also the important carbon sources/intermediate substrates in glycolysis/tricarboxylic acid cycle. The optimum concentration of substrates in these studies was found to be 0.7% (w/v) each of glucose or succinate in mineral salt medium. At this level, the batch MFC model can maintain the maximum power output more than three days. Higher concentrations of substrate did not increase net power and, in fact, led to a reduced power density. Other common substrates, such as acetate and formate, which had been utilized as electron donors in many MFCs, were not suitable for MFC solely using P. aeruginosa. Not only was there no net power output, but also the bacteria could not survive and grow in medium with these substrates as the sole carbon source. These findings confirm that P. aeruginosam, and more generally other individual bacteria species, can only utilize specific substrates. This suggests the mixed cultures would be more efficient in processes such as wastewater treatment, which… Advisors/Committee Members: Comfort, Donald (Committee Chair).

▼ Cellulosic biomass, including waste products of agricultural and industrial activities, is one of the most unused and abundant renewable energy resources in the world. The direct production of hydrogen and electricity from cellulose offers the potential of integrating the treatment of cellulosic waste and the production of clean fuel and power resources. The fermentation of cellulosic materials presents a sustainable means of biohydrogen production, but few studies supplied comparable data on cellulose conversion and hydrogen yield. Six mesophilic Clostridium species were quantitatively characterized in standardized batch experiments using MN301 cellulose, Avicel, and cellobiose. Results showed clostridia varied in H2 production, substrate degradation, biomass accumulation, and fermentation product distribution. Of the species tested, C. cellulolyticum and C. populeti catalyzed the highest H2 production with cellulose, with H2 yields of 1.69 and 1.64 mol H2/mol hexose on MN301 and 1.57 and 1.44 mol H2/mol hexose on Avicel, respectively. This standardized comparison provides a quantitative baseline for improving H2 production from cellulose through medium and process optimization and metabolic engineering. Microbial fuel cells (MFCs) convert biodegradable materials into electricity, potentially contributing to an array of renewable energy production strategies tailored for specific applications. Compared with soluble substrates, cellulose is unique because it requires a microbial consortium that can both metabolize insoluble cellulose from suspension and reduce the insoluble anode. Since no known microorganisms can do both functions, the conversion of cellulosic biomass to electricity requires a synergistic microbial community. Electricity was generated from cellulose in an MFC using a defined coculture of the cellulolytic fermenter Clostridium cellulolyticum and the electrochemically active Geobacter sulfurreducens. In fed-batch tests using two-chamber MFCs, the coculture achieved maximum power densities of 143 mW/m2 (projected anode surface area) and 59.2 mW/m2 from 1 g/L carboxymethyl cellulose (CMC) and MN301 cellulose, respectively. Neither pure culture alone produced electricity from these substrates. Cellulose conversion to electricity was also demonstrated using an uncharacterized mixed culture from activated sludge, and bioaugmentation was achieved by adding Clostridium to enhance cellulose degradation. The microbial ecology of the defined coculture of C. cellulolyticum and G. sulfurreducens in cellulose-fed, two-chamber MFCs was further analyzed. Fluorescent in situ hybridization (FISH) and quantitative polymerase chain reaction (qPCR) showed that when particulate MN301 cellulose was used as the sole substrate, most Clostridium cells were found adhered to cellulose particles in suspension, while most Geobacter cells were attached to the electrode. By comparison, both bacteria resided in suspension and biofilm samples when soluble CMC was used. The biofilm in both systems were thin and patchy. This distinct…
