DEVELOPMENT OF HIGH-THROUGHPUT EXPERIMENTAL AND COMPUTATIONAL TECHNOLOGIES FOR ANALYZING MICROBIAL FUNCTIONS AND INTERACTIONS IN ENVIRONMENTAL METAGENOMES
(2017-05-12)
Microorganisms are ubiquitous on earth, and they interact each other to form communities, which play unique and integral roles in various biochemical processes and functions that are of critical importance in global ...
ISOTOPIC FRACTIONATION AND ANAEROBIC PHYSIOLOGY OF n-ALKANE DEGRADATION BY BACTERIAL ISOLATES AND MIXED COMMUNITIES
(2011)
In the first chapter, carbon and hydrogen isotope fractionation of n-alkanes was examined in order to compare aliphatic hydrocarbon biodegradation under oxic and anoxic conditions. Desulfoglaeba alkanexedens, a sulfate-reducing ...
Characterization of MILDEW RESISTANCE LOCUS O Mediated Pollen Tube Reception
(2017-12)
Beyond its importance for the subsistence of all plant species, and thus life on earth, plant reproduction is fundamental to all human agricultural exploits. Understanding the mechanisms regulating reproduction is central ...
AEROBIC RESPIRATION AND ECOLOGY OF Escherichia coli IN THE MOUSE CECUM
(2011)
The gastrointestinal tract contains a complex microbial ecosystem that exists in a symbiotic relationship with its host and plays an important role in maintaining human health. Escherichia coli, a facultative anaerobe, ...
Conversion of acids to alcohols by Clostridium ragsdalei strain P11: Process optimization and biochemistry
(2013)
Research focus was directed toward the development of a biocatalyst that can be used to produce commodity chemicals and transportation fuels from volatile fatty acids ubiquitous in waste biomass. Clostridium ragsdalei was ...
Responses of Belowground Carbon Dynamics to Warming in Southern Great Plains
(2012)
Compared with research on aboveground carbon (C) processes in grassland ecosystems, little is known on how belowground C processes would respond to projected global warming. In this dissertation, responses of belowground ...
Response of the soil microbiome to climate change
(2011)
Anthropogenically induced climate change is a multi-factor process that will likely exert significant pressure on biogeochemical cycling of important elements such as carbon and nitrogen in all environments. Central to the ...
Studying microbial community diversities by developing high-throughput experimental techniques and computational tools
(2018-12)
Since the advent of high-throughput technologies, the understanding of microbial biodiversity has rapidly transformed. Amplicon sequencing of phylogenetic makers, especially 16S rRNA genes has now become a well-adopted ...
Transcriptional Adaptation of Enterococcus faecalis within Macrophages and the Role of PerA in Virulence
(2011)
The intestinal ecosystem is comprised of bacteria that are both beneficial and detrimental to human health. The opportunistic pathogens residing within the gastrointestinal tract typically function as commensal members ...
Microbial Ecology of Coastal Ecosystems: Investigations of the Genetic Potential for Anaerobic Hydrocarbon Transformation and the Response to Hydrocarbon Exposure
(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 ...
