Creator:: Saini, Gaurav
Abstract:: Dissociation between catabolism and anabolism, generically termed “metabolic uncoupling”, has been studied for aerobic cultures of Shewanella oneidensis MR-1. Under conditions promoting metabolic uncoupling, the cell yield diminishes while the substrate utilization rate remains largely unchanged. The effects of excess substrate conditions and TCS addition on the metabolism of pyruvate...

Creator:: Christensen, Kristi
Abstract:: The purpose of this research was to examine the ability of the cold water, green, marine, macroalga Acrosiphonia coalita to take up and metabolize polycyclic aromatic hydrocarbons (PAH) from seawater. Axenic suspension tissue cultures of the alga were contacted with seawater containing PAH in sealed experimental vessels. Uptake time courses...

Creator:: Halsey, Kimberly H.
Abstract:: Pseudomonas butanovora, Mycobacterium vaccae, and Nocardioides sp. CF8 utilize distinctly different butane monooxygenases (BMOs) to initiate degradation of recalcitrant chlorinated ethenes (CEs) that pollute aquifers and soils. BMO-dependent degradation of CEs such as trichloroethylene (TCE) can lead to cellular toxicities. The type and severity of TCE transformation-dependent damage can have...

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Creator:: Iverson, Justin
Abstract:: The Willamette Silt is a surficial geologic unit composed of successive Missoula Flood Deposits that underlies 3100 km2 (1200 mil) of arable land in the Willamette Valley of Oregon. The Willamette Silt protects the underlying regionally important Willamette Aquifer from agricultural contamination while acting as a semi-confining unit and a...

Creator:: Doughty, David M.
Abstract:: The regulation of monooxygenase enzymes has been demonstrated in bacteria that grow on methane and long chain-length alkanes (>C10). Less is known about monooxygenase regulation in short chain alkane oxidizing bacteria that grow on intermediate chain-length alkanes C2-C10. This dissertation focuses on the regulation of butane monooxygenase (BMO) expression and...
