THE ANAEROBIC MICROBIAL METABOLISM OF ENERGY SUBSTRATES: AN EXPLORATION INTO COALBED METHANOGENESIS, THE BIODETERIORATION OF DIESEL FUEL, AND BIOCORROSION
(2013-12)
Under anaerobic conditions the complete mineralization of energy substrate can be achieved by specialized individual microorganisms or through syntrophic partnerships involving bacteria and archaea that ultimately convert ...
Discovery, purification and characterization of antifungal proteins and other defense-related compounds from tropical plants.
(1999)
To date, we have screened 164 extracts from over 100 different plant species for antifungal activity against Fusarium chlamydosporum, a saprophytic/pathogenic fungus. Out of these 164 crude extracts, 111 had antifungal ...
The ecology and biogeochemistry of sulfate reduction in the terrestrial subsurface.
(1999)
I believe that the ubiquity and importance of sulfate reduction in subsurface environments is a reflection of the diversity of the hydrological and biogeochemical processes which contribute to the availability of sulfate. ...
Abiotic and biotic drivers of grassland structure: from individual to community responses
(2021-11-02)
Climate has long been recognized as an important factor in determining the spatial-temporal distribution and abundance of species, consequently influencing global biological diversity. Model projections point to changes ...
Experimental and modeling studies of canopy radiation and water use efficiencies, soil respiration and net ecosystem carbon exchange.
(2002)
Canopy radiation and water use efficiencies (RUE and WUE), soil respiration and interannual availability in net ecosystem carbon exchange (NEE) are important issues in global climate change study. This thesis summarized ...
Microbially-mediated reduction and oxidation of uranium: Implications for the bioremediation of uranium(VI)-contaminated aquifers.
(2004)
Mechanisms of nitrate-dependent U(IV) were assessed by incubating biogenic U(IV) with nitrite or Fe(III). Fe(III) rapidly but incompletely oxidized U(IV) since Fe(II) accumulated during the reaction and inhibited any further ...
Studies in the Cactaceae.
(1980)
Five taxa representing the three tribes of the Cactaceae have similar patterns of stamen and carpel initiation but display differences in early receptacle development. The first ring of stamens and the carpels arise ...
THE ECO-PHYSIOLOGY, STRESS RESPONSE REGULATION, AND ENGINEERING OF SHEWANELLA SPECIES FOR INDUSTRIAL AND ENVIRONMENTAL APPLICATIONS
(2016-11-28)
In recent decades, there has been tremendous interest in applying environmental microbiology for waste treatment, bioremediation and sustainable energy production. As one of the most important model environmental microbes, ...
Molecular systematics of Artemisia section Tridentatae (Asteraceae).
(1997)
Chloroplast DNA restriction site variation was used to examine phylogenetic relationships in Artemisia sect. Tridentatae, a complex of eleven species of woody shrubs dominant in the sagebrush communities of western North ...
