CHARACTERIZATION OF FUNGAL CONTAMINANTS IN B20 BIODIESEL STORAGE TANKS AND THEIR EFFECT ON FUEL COMPOSITION
Andrade, Oderay (2016-08)The liquid transportation fuel B20 biodiesel is an 80:20 blend of petroleum-derived ultra-low sulfur diesel (ULSD) and biodiesel. Although B20 biodiesel represents a fungible fuel with a reduced carbon footprint compared ... -
Ecological Investigations of Hydrocarbonoclastic Microbial Communities Associated with the Built-Environment
Marks, Christopher (2016-09)Evidence for the microbial metabolism of hydrocarbons is routinely identified in diverse habitats, but particularly those associated with the production, processing, storage and use of petroleum. In these environments, ... -
Impact of Photooxidation and Biodegradation on the Fate of the Oil Spilled During the Deepwater Horizon Incident: The Advanced Stages of Weathering
Harriman, Brian (2016-12)The major biogeochemical forces influencing the environmental fate of spilled oil have been intensively investigated for many decades. The sinking and burying of spilled residual oil to form large mats that subsequently ... -
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 Ecology of Coastal Ecosystems: Investigations of the Genetic Potential for Anaerobic Hydrocarbon Transformation and the Response to Hydrocarbon Exposure
Johnson Duffner, Jamie (2017-04-24)Microbial-mediated hydrocarbon transformation plays a vital role in the attenuation of natural and anthropogenic-sourced petroleum contamination in the environment, particularly in marine systems. Indigenous microbial ... -
NADH-DEPENDENT, FERREDOXIN-INDEPENDENT HYDROGEN PRODUCTION IN TWO MODEL SYNTROPHIC BACTERIA
Losey, Nathaniel (2019-05-10)The relationship between a fatty acid-oxidizing, hydrogen-producing bacterium and a hydrogen consuming methnogenic partner has longed served as a model system for anaerobic syntrophic metabolism. This process is dependent ... -
The role of Gammaproteobacteria in aerobic alkane degradation in oilfield production water from the Barnett Shale
Thornton, Meredith (2017-12)Despite nearly a century’s worth of research focused on investigating the activities of microorganisms in petroleum production systems, a large gap in the literature exists on the role of heterotrophic microorganisms in ... -
A Semi-Continuous System for Monitoring Microbially Influenced Corrosion
Eid, Mary (2018)Microbially Influenced Corrosion (MIC), also known as biocorrosion, has significant impacts on the environment and economy. Typical systems to study biocorrosion are either dynamic (once-through flow) or static (serum ... -
Substitutional Analysis of Cysteine Residues and Preliminary Regulon Analysis of the Redox-Sensing Transcription Regulator MsvR in Methanosarcina acetivorans
Gilcrest, Kylie (2016-12)Methane produced from methanogenesis in archaea may be a promising source of renewable energy as methanogens are the primary producers of biogenic methane. However, methanogens are anaerobic and experience transient oxygen ...
