Applying Anaerobic Microbial Cultivation, Molecular Techniques, and In-Silico Taxonomy to the Mammalian Microbiome
Miller, Samuel (2024-08-01)The mammalian gastrointestinal tract is an ecosystem home to a considerable number of bacteria, archaea, microeukaryotes, viruses, and their genomic components, collectively termed the "microbiome." This microbiome consists ... -
An Assessment of Microbial Communities and Their Potential Activities Associated with Oil Producing Environments
Nunn, Heather (2015-06)Microbial populations have been found in oil-associated environments as early as the 1920s. The proliferation and metabolic activities of these microorganisms can have profound deleterious effects on the infrastructure ... -
BIOFUELS (HYDROGEN AND ETHANOL) PRODUCTION OF CLOSTRIDIUM BY CELLULOSE BIOCONVERSION
Liu, Wenbin (2018-05)In view of the realization that fossil fuels reserves are limited, the dramatically increasing consumption of fossil fuels raised concerns for the energy security in the recent decades. Alternative energy generating options ... -
Digging Deeper: Enhancing Archaeoparasitology By Combining Molecular Methods With Traditional Morphological Approaches
Cleeland, Lauren (2015-05-01)Coprolite science, human parasitism and ancient DNA methodology, converge most appropriately in the sub-specialty of archaeoparasitology – the study of prehistoric parasitism. In this study, we have applied targeted PCR ... -
THE ECO-PHYSIOLOGY, STRESS RESPONSE REGULATION, AND ENGINEERING OF SHEWANELLA SPECIES FOR INDUSTRIAL AND ENVIRONMENTAL APPLICATIONS
Xie, Ming (2016-11-28)In recent decades, there has been tremendous interest in applying environmental microbiology for waste treatment, bioremediation and sustainable energy production. As one of the most important model environmental microbes, ... -
ENHANCING ALCOHOL PRODUCTION IN CLOSTRIDIUM CARBOXIDIVORANS STRAIN P7T AND THE ROLE OF TANDEM ADH GENES
Ukpong, Michael (2014)Clostridium carboxidivorans P7 is one of three microbial catalysts capable of fermenting synthesis gas (mainly CO, CO2 and H2) to produce the liquid biofuels ethanol and butanol. Gasification of feedstocks to produce ... -
EVALUATION OF METHANE-OXIDIZING BACTERIA PHYSIOLOGICAL RESPONSES TO CHANGES IN OXYGEN CONCENTRATION, INTERACTIONS WITH NON-METHANE-OXIDIZING HETEROTROPHIC BACTERIA, AND THE TAXONOMIC CLASSIFICATION OF METHYLOCYSTIS SUFLITAE SP. NOV.
Garner, Christopher (2024-05-10)This work describes an in-depth investigation into how the methane-oxidizing bacteria (MOB) respond to changes that allow them to effectively function in their ecological role. This includes understanding their response ... -
FUNCTIONAL GENOMICS STUDIES OF CLOSTRIDIUM CELLULOLYTICUM FOR LIGNOCELLULOSE BIOCONVERSION
XU, TAO (2016-12)The astonishing consumption of fossil fuels arouses serious concerns over energy security and environmental sustainability. Lignocellulosic biofuel, as a sustainable and carbon-neutral energy that can be produced from ... -
Heirloom Microbes: a survey of lactic acid bacteria in traditional Mongolian dairy
Fulton, Shannon (2020)Fermentation has sustained human communities for thousands of years. Through most of that time, humans unknowingly used microbes in food production, especially dairy. It wasn’t until the late nineteenth century that the ... -
THE HUMAN GASTROINTESTINAL MICROBIOME: INSIGHTS INTO THE MICROBIAL COMMUNITY STRUCTURE AND ANTIBIOTIC RESISTOME
O'Neal, Lindsey (2017)The human gastrointestinal microbiome consists of approximately 10-100 trillion symbiotic microbial cells. Recent advances of molecular based approaches have enhanced the ease and rapidity with which the microbial community ... -
The influence of nitrate on the short-term corrosion of steel catalyzed by marine microorganisms
Herath, Anjumala (2019-12)Microbiologically influenced corrosion (MIC) is of global concern and a threat due to its economic, environmental as well as public health implications. Identifying the factors that govern or influence MIC is beneficial ... -
AN INVESTIGATION INTO THE DISTRIBUTION OF MYXOBACTERIA, THE EFFECT OF PREDATOR-PREY INTERACTIONS ON SECONDARY METABOLITE EXPRESSION, AND DRIVERS OF MICROBIAL COMMUNITY ASSEMBLY
Bill, Brian (2019)The myxobacteria are Deltaproteobacteria capable of growing on a wide range of bacterial and fungal prey. To kill their prey, myxobacteria produce diverse secondary metabolites, many of which have medically desirable ... -
Microbial mediated carbon and nitrogen feedbacks to elevated CO2 and switchgrass establishment in grassland ecosystems
Bates, Colin (2021-10-26)Anthropogenic climate change is the greatest scientific and political challenge of the twenty-first century. Since the industrial revolution, global climate change has elevated greenhouse gas concentrations in the atmosphere, ... -
MICROBIOLOGICALLY INFLUENCED CORROSION OF CARBON STEEL IN SULFIDOGENIC ENVIRONMENTS: THE LINK TO THIOSULFATE REDUCTION AND BIOLOGICAL STABILITY OF ALTERNATIVE FUELS
Liang, Renxing (2015-12)Biocorrosion or microbiologically influenced corrosion (MIC) refers to the mutiple underlying mechanisms wherein microbial activity directly or indirectly enhances the corrosion of metallic and non-metallic materials. ... -
Novel Techniques for the Description and Interpretation of Microbial Communities in the Modern Human Gut and Ancient Human Oral Microbiome
Mann, Allison (2018)Studies of human–associated microbial communities are increasingly integrated into biological anthropology, allowing us to explore the role of microorganisms in aspects of human evolution, health, and disease. Despite ... -
Phenotypic, Chemotaxonomic and Genomic Characterization of a Novel Anaerobic Acetogen, Clostridium muelleri sp. nov. P21T Isolated from Old Hay
Doyle, Dena (2020-05)Acetogens are a group of obligately anaerobic bacteria that use the Wood-Ljungdahl (acetyl-CoA) pathway for the production of acetyl-CoA from 2 moles of CO2. Acetyl-CoA is then converted to various acids and alcohols such ... -
