▼ Scheffersomyces stipitis (=Pichia stipitis) is a xylose-fermenting and assimilating yeast (Ascomycota: Saccharomycotina) consistently isolated from the gut of Odontotaenius disjunctus (Coleoptera: Passalidae). This filamentous yeast is often attached to the wall of the posterior hindgut of the beetle by a holdfast. Gallery walls of white-rotted wood inhabited by the beetle are lined with macerated wood and frass that includes the yeast and other microbes. Previous studies have mentioned the relationship between the passalid and this yeast; however, passalid beetles also harbor a community of prokaryotes in their guts that have not been characterized. Experiments using culturing and cloning techniques and whole gut isolations have been performed in this work to characterize gut microbes. Introduction of yeast-free diets as well as diets lacking hemicellulose backbone components xylose and xylan served to test the hypothesis that S. stipitis is associated with the beetle host due to continuous environmental transmission. Treatments with antibiotics were attempted to selectively remove the yeast that is attached to the gut. Because attempts to cure the beetle of the yeast failed, introduction of foreign yeasts was performed to determine if the hindgut is saturated with microbes and to determine if the native yeast can be removed or replaced. Microsatellite and species-specific probes were used to confirm that the identity of the yeasts recovered were the same as those introduced. Results showed six taxa of three major groups, γ-Proteobacteria, β-Proteobacteria, and Firmicutes, were represented in easily isolated, culturable prokaryotes of passalid beetle guts. Diet manipulation without removing the native yeast suggested that continued recruitment from the environment might not be necessary for adults for up to 11 days. All treatments with antibiotics failed to selectively remove the yeast from the beetle surface and gut. Yeasts introduced in feeding experiments showed that non-native yeasts could be maintained for up to ten days after feeding, evidenced by microsatellite primers; however, the native yeast was never displaced. Production of a holdfast by the non-native yeasts was not observed when gut tissues were examined with light microscopy. Additionally, killer factors of the native and foreign yeasts were not discovered.

▼ The transposase-derived transcription factors FAR-RED ELONGATED HYPOCOTYL 3 (FHY3) and FAR-RED IMPAIRED RESPONSE 1 (FAR1) hold multifunctional roles in A. thaliana, such as in resetting the circadian clock, flowering and chloroplast division. This thesis aimed to investigate the cause of extensive leaf-lesion formation observed in fhy3 far1 mutants, reminiscent of the programmed cell death (PCD) associated with plant defence responses. Global gene expression analysis suggested a constitutively activated defence response in fhy3 far1 mutants causing the mutant's leaf-lesions. However, defence marker gene expression associated with Salicylic Acid (SA)- and Jasmonic Acid (JA)/Ethylene (ET)-signalling, the two groups of signalling compounds that mediate defence response, was downregulated at the same time. Analysis of transcriptional changes upon biotic challenges suggested that this was the result of negative regulatory feedback in fhy3 far1 mutants. A microarray analysis of key differentially expressed genes in fhy3 far1 mutants revealed an upregulation of the pro-PCD gene CYSTEINE-RICH RECEPTOR-LIKE PROTEIN KINASE 13 (CRK13) and a downregulation of the PCD-inhibiting METACASPASE 2 (MC2). The function of CRK13 and MC2 in PCD suggested that their misregulation in fhy3 far1 mutants could be part of the primary reason for increased leaf-lesion formation in double mutant plants. Transcriptional analysis of responses to biotic challenges in MC2 and CRK13 misexpression lines, however, revealed little similarity to the responses seen in fhy3 far1 mutants. A constitutively activated defence response infers alterations of the associated microbiota. Initial investigations indicated that the fhy3 far1 mutant plant's phenotypical changes of extended leaf-lesion formation will be very likely to affect the phyllosphere, which prompted a next generation sequencing investigation of the phyllospheric microbiota. Its composition showed greatly increased species richness and a more even spectrum of abundances of bacterial species in fhy3 far1, a pattern that is commonly associated with continuing environmental disruption. The WT phyllosphere showed a stronger domination by a few species that were associated with the production of antimicrobials. In addition, the fungal community in fhy3 far1 mutant plants contained more pathogenic fungi in comparison to more saprotrophic fungi in WT. These findings support the suggestion that pathogen-protective properties of beneficial microbes in the phyllosphere are a community characteristic linked to microbial competition.

▼ Microbes rely on collective behaviours, such as communication and cooperation to survive and form communities. The majority of these social behaviours are mediated by the secretion of public good molecules into a shared environment such that they can be utilized by neighbouring cells. Therefore, individuals that engage in costly cooperative behaviour are susceptible to exploitation by selfish cheats that gain the benefit of cooperation without investing their share of the public good cost. Understanding such bacterial social interactions and the underlying molecular mechanisms gives insight into their complex social life in natural environments and can be used to develop alternative treatments for pathogenic bacteria that rely on such social interactions for virulence and to infect hosts. In this thesis I examine social behaviours expressed by the opportunistic pathogen, Pseudomonas aeruginosa. I develop an understanding of bacterial social dynamics, particularly competitive dynamics between cooperator and cheat strains and strains that engage in bacteriocin-mediated chemical warfare. I investigate bacterial cheat-cooperator systems in several ways: 1) I begin with a review describing the evolution of and response to cheating across a range of organisms and discuss the confusion that arises in identifying cheats particularly in microbial studies and therefore propose a key to identify cheating behaviour. 2) I empirically test whether cheating behaviour is context dependent in bacterial populations and reveal that the ability to cheat varies with the abiotic and social environment, which are two fluctuating conditions in natural environments. 3) I take an experimental approach to investigate why cheat invasion is not commonly observed in natural bacterial populations by testing the effect of cooperative bacterial growth dynamics on cheating ability. I find that secretion of public goods varies with bacterial growth dynamics and physiological growth stages which may explain why cheat invasion is more commonly observed in lab cultures and not in established natural populations. 4) In the final chapter I experimentally use natural isolates to examine the role of bacteriocins in mediating competition in pathogenic populations and find that contrary to empirical and theoretical work, bacteriocins do not play a significant role in strain competitive success and dominance. The thesis has laid groundwork for studying and understanding the role of social behaviours in bacterial systems and for further exploring social dynamics in natural bacterial populations.

▼ ENGLISH ABSTRACT: Biochar (charcoal) is lauded by many scientists as an effective way to remove carbon dioxide from the atmosphere and storing it in a very stable form in the soil for hundreds to thousands of years, whilst promoting soil fertility and productivity. Considering that no significant amounts of charcoal are presently accumulating in the environment, despite considerable amounts produced globally in natural and man-made fires, this study focuses on understanding the degradation of biochar and its interactions with plants and soil organisms. The following experiments were conducted to achieve this goal. Controlled chemical oxidation of biochar, using different concentrations of hydrogen peroxide, was conducted in an attempt to mimic the enzymatic degradation of biochar by basidiomycetes. The changes occurring in biochars structure and chemistry were assessed afterwards. Furthermore, aerobic and anaerobic digestion of biochar was conducted in vitro, and in vivo to investigate the changes occurring in biochar‘s elemental composition and chemistry during oxidation and factors that play a determining role in the rate of biochar degradation. The influence of biochar in soil on free-living and symbiotic microbial communities as well as its impact on total plant biomass production and root development was assessed in three greenhouse pot trials using wheat and green beans as test plants It was proven that biochar is almost fully H2O2-degradable, mostly through hydroxylation and carboxylation reactions which led to the formation of various short chained carboxylic acids, surface saturation with acidic functional groups as determined by the surface acidity measurements and proven by the increase in the intensity of FT-IR peaks associated with carboxyl and phenolic C-O groups. Furthermore, hydrogen peroxide treatment resulted in preferential removal of volatile organic carbons and led to the purification of biochar as evident by the new, more intense and sharper peaks in the region of 1600-1000 cm-1. These FT-IR peaks are considered as the more recalcitrant fraction of biochar and were shown to be mostly associated with transformation products of lignin and cellulose formed during pyrolysis. The incubation trial confirmed that biochar cannot be utilized as a sole carbon source without the addition of nutrients or glucose, to activate microbial activity within the columns. Furthermore, abiotic oxidation can be facilitated by oxidative soil minerals such as birnessite, but oxidation with atmospheric oxygen did not result in the evolution of CO2 from biochar. The average CO2 production in pot trials without plants in both the fertilized and unfertilized treatments increased linearly (R2= 0.80; 0.79 respectively) with increasing biochar application rates when biochar was the main carbon sources. Anaerobic degradation of biochar by a methanogenic consortium was much more efficient in utilizing biochar as a carbon source, compared to aerobic digestion. The anaerobic digesters maintained a chemical oxygen demand (COD)… Advisors/Committee Members: Rozanov, Andrei, Botha, A., Stellenbosch University. Faculty of AgriSciences. Dept. of Soil Science..

▼ Anthropogenic actions have significantly increased biological nitrogen (N) availability on a global scale. In tallgrass prairies, this phenomenon is exacerbated by land management changes, such as fire suppression. Historically, tallgrass prairie fire removed N through volatilization, but fire suppression has contributed to increased soil N availability as well as woody encroachment. Because soil microbes respond to N availability and plant growth, these changes may alter microbial composition and important microbially-mediated functions. Grassland management affects the soil environment on multiple time scales including short (fertilization or fire event), seasonal (growing vs. non-growing season), and long-term (decadal plant turnover and nutrient accumulation), therefore my goal was to understand community variability at different time scales affecting the population and community dynamics of soil microbes. I predicted soil microbes would be sensitive to environmental changes at all time scales, seasonal variation would reflect increased plant rhizodeposit-supported populations during summer and decomposers during winter, and long-term fire suppression and chronic fertilization would drive soil microbial community turnover associated with accumulation of plant litter and N. To address these predictions, soils were collected from the Belowground Plot Experiment (BGPE) at Konza Prairie Biological Station: a 30-y factorial field manipulation of N fertilization and burning. Surface soils (0-15 cm) were sampled monthly between Nov 2014 – Dec 2015, including one week post-fire (April) and post-fertilization (June). Genomic DNA was extracted from each sample for qPCR and PCR for Illumina MiSeq library sequencing of the prokaryotic 16S rRNA gene and fungal ITS, to estimate population and community dynamics of soil microbes. Soil environmental characteristics and plant communities were measured in July 2015 to evaluate correlations between plant and microbial communities, and environmental variability. Soil microbial responses to short-term fire/fertilization events were minimal, while microbial population sizes fluctuate seasonally and synchronously, and microbial community composition varied more with management history than at shorter time scales. Bacterial populations increased 10x during growing-season plant rhizodeposition, while fungal populations were less dynamic, but decreased in fall, possibly reflecting a shift to subsistence on soil organic matter. In contrast, microbial community composition was seasonally stable, but distinct between long-term management treatments, which may indicate accumulation of niche-defining plant or soil properties over decades. Prokaryotic communities responded to altered N availability via both fertilization and loss due to fire, with the highest abundance of "copiotrophic" (r-selected) taxa in unburned, fertilized soils. Fungal communities responded to N fertilization with higher abundance of arbuscular mycorrhizal fungi, pathogens, and saprotrophs, possibly due to changes in… Advisors/Committee Members: Lydia H.

▼ Marine microbes control the flux of energy and chemicals in the ocean and therefore mediate ocean productivity and biogeochemistry, which ultimately sustains marine life and controls global climate. A numerically and functionally important group of marine microbes, for which there is currently a significant gap in knowledge regarding their ecology and biogeography, are the photoheterotrophic bacteria. These microbes, including both Aerobic Anoxygenic Phototrophic Bacteria (AAnPB) and proteorhodopsin based phototrophic bacteria and Archaea (PRBA) comprise up to 70% of microbial communities within surface waters of the ocean. Capable of gaining energy from light-induced proton translocation and from the oxidation of organic material, these often highly abundant bacteria have been proposed to significantly influence marine biogeochemistry and trophodynamics. However, the environmental (i.e. physicochemical, seasonal, oceanographic) factors influencing the abundance and diversity of these organisms are currently poorly defined, particularly within the often highly productive waters of the Southern Hemisphere. The aim of this thesis was to examine changes in photoheterotrophic community abundance and composition in coastal waters of Australia and identify the key environmental influences on the ecology of these microbes. Samples collected from a combination of oceanographic research voyages and time-series sampling regimes were analysed using both amplicon sequencing approaches and quantitative PCR targeting pufM and proteorhodopsin genes to characterise AAnPB and PRBA populations respectively. High temporal resolution analysis of photohetetrophic bacterial population dynamics in the coastal waters of Australia indicated seasonality in the abundance and diversity of these groups. Along the eastern coast of Australia, AAnPB abundance was highly variable, with pufM gene copies ranging from 1.1 x 10² to 1.4 x 10⁵ mL⁻¹, and positively correlated with day length and solar radiation. pufM gene amplicon sequencing revealed that the majority of sequences were closely related to those obtained previously in other environments, suggesting that key AAnPB groups are widely distributed across similar environments globally. Temperature was a major structuring factor for AAnPB assemblages across large spatial scales, correlating positively with richness and Gammaproteobacteria (phylogroup K) abundance, but negatively with Roseobacter-clade (phylogroup E) abundance, with temperatures between 16-18 °C identified as a potential transition zone between these groups. Coastal PRBA assemblages were also dynamic in both space and time, with diversity correlated to indicators of waterbody oligotrophy including positively to temperature, Secchi depth and Prochlorococcus cell abundance and negatively to phosphate concentration. Shifts in taxonomic composition were best explained by temperature and day length. Seasonality in taxonomic structure was accompanied by temporal variability in proteorhodopsin spectral tuning. Finally, we provide evidence…

▼ The purpose of this research was to improve ruminal nutrient metabolism and nutrient digestion representations in the Molly cow model. First, the model accuracy and precision were assessed using a dataset including 229 studies (n = 938 treatments) conducted with dairy and beef cattle. The model evaluation results indicated the mechanisms encoded in the model relative to ruminal and total tract nutrient digestion are properly represented. However, ruminal pH was very poorly represented in the model with a RMSE of 4.6% and a concordance correlation coefficient (CCC) of 0.0. Although VFA concentrations had negligible mean (2.5% of MSE) and slope (6.8% of MSE) bias, the CCC was 0.28 implying that further modifications with respect to VFA production and absorption are required to improve model precision. As identified by the residual analyses, the representations of N recycling between blood and the gut were improved by considering ruminal ammonia outflow, intestinal urea entry, microbial protein synthesis in the hindgut, and fecal urea N excretion in the model. Observations of total urea entry, gut urea entry, and urinary urea elimination rates were collected from 15 published urea kinetics studies were used to derive related parameters. After the modifications, prediction errors for ruminal outflows of total N, microbial N, and non-ammonia non-microbial N were 39.5, 27.8 and 35.9% of the respective observed mean values. Prediction errors of each were approximately 10% units less than the corresponding values before model modifications and fitting due primarily to decreased slope bias. The revised model predicted ruminal ammonia and blood urea concentrations with substantially decreased overall error and reductions in slope and mean bias. After that, ammonia concentration as a driver was added to the pH equation, and a dataset assembled from the literature containing 284 peer reviewed studies with 1223 treatment means was used to derive parameter estimates for ruminal metabolism and nutrient digestions. Refitting the parameters significantly improved the accuracy and precision of the model predictions for ruminal nutrient outflow (ADF, NDF, total N, microbial N, non-ammonia N, and non-ammonia, non-microbial N), ammonia concentrations, and fecal nutrient outflow (protein, ADF, and NDF). Therefore, the improved model can be used to simulate nutrient degradation and digestion in the bovine. Although minor mean and slope bias were observed for ruminal pH and VFA concentrations, the small values for concordance correlations indicated much of the observed variation in these variables remains unexplained. To further explain variance in ruminal metabolism and understand how ruminal pH affects the microbial community, expression of carbohydrate-active enzyme transcripts (CAZymes), fiber degradation, and short chain fatty acid (SCFA) concentrations, six cannulated Holstein heifers with an initial BW of 362 ± 22 kg (mean ± SD) were subjected to 2 treatments in a cross-over design.

▼ Arsenic is the most pervasive environmental toxic substance. As a consequence of its ubiquity, nearly every organism has genes for resistance to inorganic arsenic. In one project I examined the role of glutaredoxin 2 (Grx2) in reduction of arsenate to arsenite. I demonstrated that Grx2 has both glutaredoxin thiol transfer activity and glutathione S-transferase (GST) activity. In a second project investigated arsenic resistance in a microbiome organism. I discovered that the human gut microflora B. vulgatus has eight continuous genes in its genome and these genes form an arsenical-inducible transcriptional unit. In two other projects I investigated the properties of two As(III) S-adenosylmethionine (SAM) methyltransferase (ArsM in microbes and AS3MT in animals). In this project we demonstrate that most fungal species have ArsM orthologs with only three conserved cysteine residues, and AfArsM from Aspergillus fumigatus methylates only MAs(III) and not As(III). For human, arsenic methylation process is thought to be protective from acute high-level arsenic exposure. However, with long term low-level exposure, hAS3MT is thought to produce intracellular methylarsenite (MAs(III)) and dimethylarsenite (DMAs(III)), which are considerably more toxic than inorganic As(III) and may contribute to arsenic-related diseases. Several single nucleotide polymorphisms (SNPs) in putative regulatory elements of the hAS3MT gene have been shown to be protective. In contrast, three previously identified exonic SNPs (R173W, M287T and T306I) may be deleterious. I identified five additional intragenic variants in hAS3MT (H51R, C61W, I136T, W203C and R251H). I purified the eight polymorphic hAS3MT proteins and characterized their enzymatic properties. Each enzyme had low methylation activity through decreased affinity for substrate, lower overall rates of catalysis and/or lower stability. I propose that amino acid substitutions in hAS3MT with decreased catalytic activity lead to detrimental responses to environmental arsenic and may increase the risk of arsenic-related diseases.

▼ Background: The Bullitt Center is a six-story, 50,000 square-foot green building that emphasizes energy efficiency and environmental performance based on design and operation. Microorganisms found in indoor surface environments most often come from human sources or by transport from the outdoor environment. Quantity and location of surface microbes can change due to re-aerosolization with human activity and building air movement. Few studies have been performed on surface microbes in green buildings. The aims are 1) Validate a sponge processing method based on literature review and 2) Characterize microbial populations from surfaces in the Bullitt building. Methods: Three processing methods (shaker table, hand massage, and stomacher 400 circulator) were evaluated for microbial recovery from 3MTM sampling sponges with 10 ml neutralizing buffer. Sponges were spiked with 1 to 3E8 E. coli B cells and cells recovered by each method. DNA from recovered cells was extracted (MO BIO PowerSoilTM DNA Isolation Kit), quantified by nanodrop (ND-3300) using picogreen, and E. coli specific targets amplified by qPCR (with fluorescent probe). The best processing method was determined by examining both percent recoveries of CFU and C(t) values. The Bullitt surface samples were processed by the most efficient elution method followed by DNA extraction, nanodrop quantification of nucleic acid, and Illumina 16S metagenomic sequencing to characterize the microbes that were present. Results: Hand massage was determined to be the most effective elution method based on the highest and most consistent calculated percent recoveries of CFUs ranging on average from 32.2-69.3%. C(t) values gave inconsistent results using undiluted nucleic acid, but tighter results using 10-fold dilutions of the sponge extractions ranging from (16.7-35.8% for shaker table, 15.3-42.1% for hand massage, and 25.7-52.7% for stomacher) suggesting the presence of inhibitors. Throughout the study, nucleic acid results ranged from (0-5121.5 ng/ml). The highest nucleic acid values were observed in June ranging from (78.1-5121.5 ng/ml). Results from Illumina 16S (>10% OTUs) showed changes in microbial populations over time at each location. Results from all 16S data showed that the high bloom conditions for Streptophyta were observed in April 2014 with a percent abundance as high as 93.9%. The high bloom conditions for Sandaracinobacter were observed in August/November 2013 with a percent abundance as high as 40.1%, then decreases significantly for the rest of the timeline. Data on the top ten microbes based on the number of reads in each sample showed high abundance levels of environment associated microbes and distinct levels of human associated microbes in June. Conclusion: Validation of hand massage as a sponge processing method was the best compared to the shaker table and stomacher methods and can be used for future studies to characterize microbial populations. Nanodrop and Illumina 16S results provided information in the change of quantity of surface microbes at each… Advisors/Committee Members: Meschke, John S (advisor).

University of Minnesota M.S. thesis. August 2012. Major: Animal sciences. Advisor: Marshall D. Stern. 1 computer file (PDF); v, 87 pages.

An experiment was performed to investigate if fermentation biomass (FB), a dried bacterial co-product derived from lysine production (Ajinomoto Heartland, Inc.) can be used as a protein source in ruminant diets. Eight dual-flow continuous culture fermenters were inoculated with rumen fluid and used during one experimental period consisting of a 7-d adaptation period followed by 3 sampling days. Substrate for the microbes was provided by one of two isonitrogenous diets, CON or DFB. In CON, soybean meal (SBM) provided 57% of total CP, and in DFB, SBM and FB provided 12 and 45% of total CP, respectively. CON contained 3% molasses, 16% ground corn, 13% grass hay, 48% corn silage, and 20% SBM on a DM basis. DFB contained 3% molasses, 18.4% ground corn, 13% grass hay, 50% corn silage, 8.5% SBM, and 6.7% FB. Fermenters were supplied with 75 g/d of DM divided into 8 equal portions. Anaerobic conditions were maintained by infusion of N2; pH was maintained between 5.8 and 6.8; and temperature was set at 39C. On sampling days, liquid and solid effluent were collected, combined, and homogenized to be used for chemical analysis and in vitro estimation of intestinal digestibility (ID). Treatment did not affect (P > 0.1) average, maximum, or minimum fermenter pH. There was no effect (P > 0.1) on apparent or true OM, NDF, or ADF digestibility (%) or total VFA (mM), although branched-chain VFA (mM) was higher (P = 0.01) in CON because isobutyrate (mol/100 mol) tended (P = 0.06) to increase with CON treatment. Source of N had no effect (P > 0.1) on total, dietary, or bacterial-N flows. Addition of FB decreased (P < 0.05) NH3-N flow from 0.4 to 0.2 g/d and tended to decrease (P =0.06) effluent NH3-N concentration from 17.1 to 9.7 mg/100 mL. His and Met flows increased (P < 0.05) from 0.48 to 0.53 and 0.18 to 0.20 g/d, respectively, when FB partially replaced SBM in the diet, but there were no effects (P > 0.1) on other AA or total AA flows. There was a trend (P = 0.08) in percent non-essential AA input (CON = 73.6% vs. DFB = 82.2%) in effluent; however, there was no effect (P > 0.1) on percent of essential AA or total AA input in effluent. Effluent from the DFB treatment was higher (P < 0.05) in ID than CON (CON = 70.4% vs. DFB = 79.6%). These results indicate that FB elicited a similar response in N metabolism and AA flows to SBM but had a higher estimated digestibility in the intestine, and has potential use as a protein source in ruminant diets. In a second experiment, rumen fluid was collected from 4 steers fed the same diet, and 3 populations of rumen microorganisms (liquid-associated bacteria (LAB), solid-associated bacteria (SAB), and liquid-associated protozoa (LAP)) were isolated by differential centrifugation. Intestinal digestibility of N (ID) was determined using the in vitro (pepsin and pancreatin) steps of the 3-step procedure of Calsamiglia and Stern (1995). Total-N content…

▼ Microbial fuel cells (MFCs) are bioelectrochemical devices that allow the harvesting of electricity generated during anaerobic respiration of selected bacterial species. This technology shows promise in both wastewater treatment and sustainable bioenergy conversion applications. Bacterial respiration occurs in the anaerobic anode compartment of the MFC, and is electrochemically coupled with electron acceptors in the MFC's aerobic cathode compartment. This dissertation addresses a variety of MFC applications and includes a comprehensive summary of the published results of bacterio-algal MFCs. This review summarizes not only successful published results of bacterio-algal fuel cells but also highlights critical operational parameters and their effect on power generation and output efficiency. Power generation and desalination performance of microbial desalination cells (MDCs) were compared using two different catholytes; (1) Nanochloropsis salina, a marine algae and (2) potassium ferricyanide in chapter three. Anodic biofilms and current generation during biofilm growth were examined using single chambered MFCs submersed in algal catholyte. As part of the dissertation research study, we conducted experiments to explore the role of graphite anodes in the decolorization of Reactive Black 5 (RB5) azo dye and Reactive Blue 4 (RBL4) anthraquinone dye coupled with voltage generation in MFCs. Desalination efficiencies were 45%, 79%, and 46% when the algae were used as catholyte and 46%, 73%, and 16% when KFe(CN)6 was used as theiicatholyte at (35, 17.5, and 8.25 g/L of NaCl) respective salt concentrations. Confocal laser scanning microscopy imaging showed that the depth of the bacterial biofilm on the anode was about 65 µm. There were more viable bacteria on the biofilm surface and near the biofilm-electrolyte interface as compared to those closer to the anode surface. RB5 dye was more than 90% decolorized in 120, 165, and 225 min at 50, 100 and 200 mg L-1 dye concentrations, respectively. RBL4 at 50 and 100 mg L-1 took 225 and 300 min to decolorize, while 200 mg L-1 RBL4 dye was not decolorized at all. The reason may be substrate inhibition of the reductase enzyme or the selective transfer of electrons to the anode and not the dye. The results successfully demonstrated that the marine algae assisted biocatholyte can be used for efficient desalination in MDCs, but generates lower power as compared to the chemical catholyte. Biofilm growth on the anode creates a conductive layer, which can help overcome mass transport limitations in MFCs. Higher external resistance favors faster decolorization, and the reductive cleavage is faster with azo dyes than anthraquinone dyes. Advisors/Committee Members: Christy, Ann (Advisor).

▼ Gastrointestinal (GI) health is an important contributor to one?s overall well-being. In the past decade, the focus of this aspect of health has been on the organisms that inhabit the intestines: gut microbes. A concept central to understanding bacterial behavior for health or disease promotion is biological film (biofilm) formation. The predominant form of growth for bacteria is biofilm formation, an as yet poorly described phenomenon for gut microbes. In order to better understand bacterial behavior in response to nutrients that pass through the GI system, a high throughput system to assess biofilm formation was developed. Gastrointestinal-associated microbes, Escherichia coli and Enterococcus faecalis, were assayed for biofilm formation in 96-well plates after 24 hours of incubation. Nutrients, inter-and intrakingdom signaling molecules such as monosaccharides, calcium, insulin, endocannabinoids, and AI-1, AI-2 like signaling compounds, respectively, were added to cultures in order to test their effects on biofilm formation. Biofilm was quantified spectrophotometrically by the measurement of optical density of each well measured at 580nm following crystal violet staining of adherent biofilm. Values were expressed as means ? standard error of the mean (SEM); differences between means were assessed using t-testing and ANOVA using GraphPad Prism, with mean differences considered significant at P < 0.05. Results showed that biofilm formation by E. coli was enhanced by glucose, galactose, lactose, AI-1 like signaling compound and insulin at 50 and 100?U/ml, while AI-2 like compound and calcium inhibited biofilm formation. Biofilm formation by E. faecalis was also enhanced by AI-1 like compound and insulin at 50?U/ml in RPMI medium and inhibited in cultures grown in BHI medium or with added calcium. We conclude that gastrointestinal-associated microbes are influenced by nutrients as well as various factors, including the culture medium, signaling compounds, as well as host-signaling compounds such as insulin and calcium. This study provides a platform required for future studies involving nutrient effect on biofilm formation.

Ph.D. University of Hawaii at Manoa 2010.

Studies directed towards the discovery of pharmaceutical lead compounds for the treatment of neoplastic and infective diseases from marine microorganisms of the Hawaiian archipelago have led to the isolation of 42 bioactive compounds, 35 of which were derived from marine bacteria, 6 from marine fungi and 1 from a sponge. The elucidation of their chemical structures using modern analytical methods resulted in the identification of 10 new secondary metabolites with pharmaceutical potential. Within the scope of this work, the most prolific strains in terms of the production of novel secondary metabolites were shown to belong to the genus Pseudoalteromonas: Two red-pigmented marine bacteria designated CMMED418 and CMMED294 were identified as previously undescribed Pseudoalteromonas spp. on the basis of 16S rRNA and gyrB gene sequences. The strains produced a new class of prodigiosins with a hitherto unprecedented substitution at C-2, supporting studies that have demonstrated the multifaceted biosynthesis of prodiginine-type secondary metabolites in various microbial organisms. The major metabolite, 2-(p-hydroxybenzyl)-prodigiosin, was active against human ovarian adenocarcinoma cells and inhibited human topoisomerase I. The structure of 2-(p-hydroxybenzyl)-prodigiosin was elucidated on the basis of homo-and hetero-correlated NMR experiments; the minor metabolites were characterized on the basis of their collision-induced fragmentation patterns using tandem mass spectrometry. Two additional Pseudoalteromonas spp., CMMED290 and CMMED291, produced 2,3,5,7-tetrabromobenzofuro[3,2-b]pyrrole, a highly brominated anti-MRSA antibiotic with a new tricyclic benzofuropyrrole core structure that is unprecedented amongst natural products. Structure elucidation was facilitated by computational methods. The IC50-value of the compound against the clinical target MRSA was evaluated and compared to other highly brominated metabolites. Lastly, the unusual production of indolmycin by the Gammaproteobacteria CMMED301 and CMMED769 prompted closer investigation of their phylogenetic origin and resulted in the chemical and biological description of the novel bacterial species Pseudoalteromonas hawaiiensis. Methods for the delineation from the seemingly closely related species Pseudoalteromonas luteoviolacea are described. In addition, further marine isolates that have yielded interesting results in the course of the analysis of their pharmaceutical potential are discussed (Table 1). These include a bioactive dioxoenoic acid, isolated from the undescribed marine bacterium CMMED169; a new nitrobenzoyl sesquiterpenoid from the marine fungus Aspergillus elegans CMMED235; the results of a large scale elicitation response experiment on marine fungi (Fusarium sp. LM252); bioactive compounds from the cyanobacterium Synechococcus sp. CMMED348; and a novel halichondramide A analog from the deep sea Pachastrissa sp. PS358.

▼ An experiment was performed to investigate if fermentation biomass (FB), a dried bacterial co-product derived from lysine production (Ajinomoto Heartland, Inc.) can be used as a protein source in ruminant diets. Eight dual-flow continuous culture fermenters were inoculated with rumen fluid and used during one experimental period consisting of a 7-d adaptation period followed by 3 sampling days. Substrate for the microbes was provided by one of two isonitrogenous diets, CON or DFB. In CON, soybean meal (SBM) provided 57% of total CP, and in DFB, SBM and FB provided 12 and 45% of total CP, respectively. CON contained 3% molasses, 16% ground corn, 13% grass hay, 48% corn silage, and 20% SBM on a DM basis. DFB contained 3% molasses, 18.4% ground corn, 13% grass hay, 50% corn silage, 8.5% SBM, and 6.7% FB. Fermenters were supplied with 75 g/d of DM divided into 8 equal portions. Anaerobic conditions were maintained by infusion of N2; pH was maintained between 5.8 and 6.8; and temperature was set at 39C. On sampling days, liquid and solid effluent were collected, combined, and homogenized to be used for chemical analysis and in vitro estimation of intestinal digestibility (ID). Treatment did not affect (P > 0.1) average, maximum, or minimum fermenter pH. There was no effect (P > 0.1) on apparent or true OM, NDF, or ADF digestibility (%) or total VFA (mM), although branched-chain VFA (mM) was higher (P = 0.01) in CON because isobutyrate (mol/100 mol) tended (P = 0.06) to increase with CON treatment. Source of N had no effect (P > 0.1) on total, dietary, or bacterial-N flows. Addition of FB decreased (P < 0.05) NH3-N flow from 0.4 to 0.2 g/d and tended to decrease (P =0.06) effluent NH3-N concentration from 17.1 to 9.7 mg/100 mL. His and Met flows increased (P < 0.05) from 0.48 to 0.53 and 0.18 to 0.20 g/d, respectively, when FB partially replaced SBM in the diet, but there were no effects (P > 0.1) on other AA or total AA flows. There was a trend (P = 0.08) in percent non-essential AA input (CON = 73.6% vs. DFB = 82.2%) in effluent; however, there was no effect (P > 0.1) on percent of essential AA or total AA input in effluent. Effluent from the DFB treatment was higher (P < 0.05) in ID than CON (CON = 70.4% vs. DFB = 79.6%). These results indicate that FB elicited a similar response in N metabolism and AA flows to SBM but had a higher estimated digestibility in the intestine, and has potential use as a protein source in ruminant diets. In a second experiment, rumen fluid was collected from 4 steers fed the same diet, and 3 populations of rumen microorganisms (liquid-associated bacteria (LAB), solid-associated bacteria (SAB), and liquid-associated protozoa (LAP)) were isolated by differential centrifugation. Intestinal digestibility of N (ID) was determined using the in vitro (pepsin and pancreatin) steps of the 3-step procedure of Calsamiglia and Stern (1995). Total-N content of each fraction was different (P < 0.05) with LAB having the highest N content (8.1 vs. 6.1 vs. 5.6% of DM for LAB, SAB, and LAP,…

▼ On intertidal sandflats, the dispersal of juvenile organisms can rely on bedload transport, a critical process during small-scale disturbance recovery. The erosion of surface sediments is also vital to benthic-pelagic coupling, where resuspended microbes and organic material become available to suspension feeders and/or transported to adjacent habitats. On sandflats, the organisms living within sediments have been proven to be key drivers of ecological function, such as benthic-pelagic coupling and biogeochemical cycling. Although benthic organisms have been recognized as important to ecological function, the role of multiple species and their interactions on sediment movement is rarely described in non-cohesive sandflats. Furthermore, the role of benthic organisms in sediment movement can vary with environmental conditions, making general sediment-benthos relationships difficult to establish. In this thesis, I examined subtle variations in the biotic and abiotic factors that influence sediment movement on intertidal sandflats. The thesis comprises three research chapters, each evaluating the relationships between benthic community structure and sediment properties. I used a backdrop of environmental stressors common to intertidal sandflats in order to incorporate the natural variations in sediment-benthos relationships that occur under environmental stress. Throughout this thesis, erosion potential was characterized by: erosion thresholds (Ʈc; N m⁻²), erosion rates (ER; g m⁻² s⁻¹), and change in erosion rate with increasing bed shear stress (me; g N⁻¹ s⁻¹). When describing erosion, a decrease in (-) Ʈc signifies an increase in initial bed erosion and an increase in (+) ER represents an increase in surface erosion. Therefore -Ʈc and +ER demonstrate surface erosion. In contrast, me was recorded during a higher bed shear stress, so that an increase in (+) me denotes more rapid changes in subsurface erosion. In chapter 2, I used a spatial gradient of increasing sediment mud (≤ 63 μm) content (0-56 %) to represent temporal increases in fine sediments that can occur as a result of terrestrial inputs. Samples were collected from intertidal flats in three estuaries (n = 45), and data pooled across estuaries to achieve the increasing mud gradient. Distance-based linear modeling (DistLM) was employed to account for the variation in erodibility using biotic and abiotic sediment characteristics. Small bioturbating macrofauna, predominantly freely motile species < 5 mm in size, destabilized surface sediments (-Ʈc and +ER), whereas microbes and organic matter were resuspended during surface erosion. In contrast, increasing mud and mean grain size stabilized subsurface sediments (+me) explaining 61 % of the variation. This study highlights the importance of abundant small bioturbating macrofauna to surface erosion, and describes the natural variation in erosion measures that occur with changes in biotic and abiotic sediment properties. In chapter 3, I manipulated macrofaunal deposit feeding grazing pressure (i.e., Macomona… Advisors/Committee Members: Pilditch, Conrad A (advisor), Moon, Vicki G (advisor).
