THE HUMAN GASTROINTESTINAL MICROBIOME: INSIGHTS INTO THE MICROBIAL COMMUNITY STRUCTURE AND ANTIBIOTIC RESISTOME
(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 ...
Enzyme systems involved in interspecies hydrogen and formate transfer between syntrophic fatty and aromatic acid degraders and Methanospirillum hungatei
(2013)
The oxidation of either the fatty acid butyrate or the aromatic acid benzoate is essential for the efficient degradation of complex organic material to methane because they are central intermediates. The oxidation of ...
DIAGNOSTIC ANALYSIS OF TERRESTRIAL GROSS PRIMARY PRODUCTIVITY USING REMOTE SENSING AND IN SITU OBSERVATIONS
(2017-12)
Vegetation play a critical role in the interactions between atmosphere and biosphere. CO2 fixed by plants through photosynthesis process at ecosystem scale is termed as gross primary production (GPP). It is also the first ...
ENHANCING ALCOHOL PRODUCTION IN CLOSTRIDIUM CARBOXIDIVORANS STRAIN P7T AND THE ROLE OF TANDEM ADH GENES
(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 ...
MOLECULAR CHARACTERIZATION OF THE ARABIDOPSIS NUCLEAR FACTOR-Y TRANSCRIPTION FACTOR FAMILY
(2014-05-09)
NUCLEAR FACTOR-Y (NF-Y) transcription factors, composed of three independent families: NF-YA, NF-YB, and NF-YC, have greatly expanded in plants in comparison to animals. For example, while humans have only one member of ...
ECOSYSTEM RESPONSES TO CLIMATE VARIABILITY AND MANAGEMENT PRACTICES: DROUGHT ASSESSMENT (REMOTE SENSING), FIELD MEASUREMENTS (EDDY COVARIANCE) AND MODELING (DNDC)
(2017-12-15)
Climate variability and management practices in isolation or in combination influence the properties of ecosystems and the flows of energy and materials through them. The goal of this dissertation is to better understand ...
AN INVESTIGATION INTO THE INFLUENCE OF SUBSURFACE GEOCHEMISTRY ON MICROBIAL COMMUNITIES IN AN UNCONFINED CONTAMINATED AQUIFER
(2018)
Microorganisms account for ~ 90 gigatons of carbon in terms of global biomass and are important drivers of elemental cycling especially in oligotrophic subsurface environments. Subsurface ecosystems remain poorly characterized ...
SINGLE-NUCLEOTIDE RESOLUTION VIEW OF GENE EXPRESSION IN ESCHERICHIA COLI K-12 UNDER VARIOUS PHYSIOLOGICAL CONDITIONS
(2015-05-08)
We analyzed the transcriptome of Escherichia coli K-12 by strand-specific RNA sequencing at single-nucleotide resolution during logarithmic- growth and upon entry into stationary phase under carbon, nitrogen, and phosphate ...
Systems analysis of grass cell wall biosynthesis for biofuel production
(2017-05)
Grass cell walls play an important role in plant development, pathogen defense, and are an abundant and sustainable carbon source for biofuel production. Chapter 1 introduces the great impact of cell wall composition on ...
FUNCTIONAL GENOMICS STUDIES OF CLOSTRIDIUM CELLULOLYTICUM FOR LIGNOCELLULOSE BIOCONVERSION
(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 ...
