Role of ppGpp in regulating global gene expression in Escherichia coli.
(2009)
Bacteria grow when nutrient availability supports basic biochemical requirements and remain in stationary phase when basic needs go unmet. This deceptively simple phenomenon requires the orchestrated expression of thousands ...
Characterization of Subsurface Microbial Communities Involved in Bioremediation of Uranium and Nitrate
(2009)
Mining and enrichment of uranium (U) for nuclear weapons and energy has left this radionuclide an important groundwater contaminant in the United States and worldwide. Migration of U in groundwater can be prevented by U ...
Discovery, isolation and characterization of novel biomolecules with nematicidal activity.
(2000)
Both, sesquiterpene lactones isolated from Ambrosia and trypsin inhibitors isolated from Cassia and from Mucuna are new potential tools to engineer transgenic plants with resistance to plant parasitic nematodes.
Peripheral and central pathways involved in the biodegradation of monoaromatic compounds under anaerobic conditions.
(2001)
Overall, the work in this dissertation contributes to our understanding of anaerobic biodegradation pathways, the role of syntrophic interactions in substrates degradation, and demonstrates a novel benzoate fermentation ...
Blastomyces dermatitidis :
(1981)
A hybridoma cell line was isolated which produced monoclonal antibody to one protein component of a yeast-phase cytoplasmic antigen of B.dermatitidis. The IgM antibody product was characterized by immunodiffusion, ...
The microbial metabolism of benzene and crude oil under diverse anaerobic conditions.
(2000)
The research reported here expands the range of knowledge for anaerobic hydrocarbon metabolism, as well as provides a sound foundation for the microbial destruction of compounds once thought to be completely recalcitrant ...
CARBON-WATER COUPLING OF TERRESTRIAL ECOSYSTEMS IN RESPONSE TO CLIMATE CHANGE AND CLIMATE VARIABILITY
(2019-05-10)
Carbon and water cycles are two fundamental biophysical processes in terrestrial ecosystems. Rain use efficiency (RUE), defined as the ratio of ecosystem productivity to precipitation (PPT), and water use efficiency (WUE), ...
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 ...
