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 ...
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 ...
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 ...
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 ...
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 ...
THE IMPACT OF LONG-TERM ELEVATED ATMOSPHERIC CARBON DIOXIDE ON BELOWGROUND MICROBIAL COMMUNITY AT CONTRAST NITROGEN CONDITIONS
(2017-12)
Global terrestrial ecosystems are subjected to various climate change factors, including the concurrent elevated CO2 (eCO2) and nitrogen deposition (eN). Despite the increasing appreciation that eCO2 and eN can interactively ...
Edward Jenner: The Mystery of the Milkmaids
(2017-08)
Edward Jenner was a physician in the eighteenth and nineteenth century who studied the disease known as cowpox. Traditional medical knowledge demonstrated that milkmaids who contracted the disease cowpox became immune to ...
Genes required for sediment fitness in Desulfovibrio desulfuricans G20.
(2007)
97 genes required for sediment fitness of G20 were identified and the identification of chemotaxis genes validated our STM screening method since it would be expected to enhance sediment fitness. The growth of these sediment ...
MICROBIOLOGICALLY INFLUENCED CORROSION OF CARBON STEEL IN SULFIDOGENIC ENVIRONMENTS: THE LINK TO THIOSULFATE REDUCTION AND BIOLOGICAL STABILITY OF ALTERNATIVE FUELS
(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. ...
Iron uptake in Gram-negative and Gram-positive bacteria.
(2006)
Bacteria, including both Gram-positive and Gram-negative bacteria, utilize iron sources from the environment. Iron uptake systems in Gram-negative bacteria are well studied. Escherichia coli FepA transports certain catecholate ...
