Characteristics of bradyrhizobium sp. recovered from Oregon soils

Creator:: Cheng, Hsin-hua
Abstract:: Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations...

Interactions between microbial dynamics, water flow, and solute transport in unsaturated porous media

Creator:: Yarwood, Rockie R.
Abstract:: Bioremediation in the vadose zone is unpredictable because of poor understanding of factors influencing microbial growth in this environment. A lab-scale experimental system was developed to examine, noninvasively, interactions between microbial growth, water flow, and solute transport in unsaturated porous media. Measurements of microbial colonization, and its impact on hydrology,...

Influences of phosphate on the growth and nodulation characteristics of Rhizobium trifolii

Creator:: Leung, Kam-tin
Abstract:: Nodulation success by two indigenous Rhizobium trifolii serogroups, 6 and 36, on subterranean clover (Trifolium subterraneum L.) was affected by the addition of phosphate to Abiqua soil (Ultic Haploxeroll). To understand the impact of phosphorus nutrition on the survival and nodulation characteristics of the two serogroups, studies were carried out...

Control of alkane monooxygenase activity and expression in Pseudomonas butanovora

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...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

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...

Community profiles of ammonia oxidizers across high-elevation forest-to-meadow transects

Creator:: Mintie, Ann
Abstract:: In recent years considerable interest has been shown in the diversity of ammonia-oxidizing bacteria in soil communities. The majority of the research has been carried out in Northern Europe where soils have received high atmospheric inputs of nitrogen over the past two centuries. In contrast, although much work has been...

Novel characteristics (Intra and Ex planta) of indigenous serogroups of rhizobium meliloti

Creator:: Busse, Matt D.
Abstract:: This thesis presents novel findings regarding symbiotic, physiological, and antigenic characteristics of representatives from an indigenous soil-borne population of Rhizobium meliloti. Nodules were sampled from 'Vernal', 'Anchor', and 'Saranac' alfalfa, and the isolates analyzed serologically. Rhizobium meliloti serogroup 31 was identified as a dominant nodule occupant, with a greater and...

Metabolism of dichloroethenes by the butane-oxidizing bacterium 'Pseudomonas butanovora'

Creator:: Doughty, David M.
Abstract:: Reductive dechlorination of chlorinated ethenes is dependent upon suitable substrates promoting microbial activity and creating anaerobic conditions. At the periphery of active reductive dechlorinating zones combinations of lesser chlorinated ethenes should exist along with end products of the anaerobic metabolism that is driving reductive dechlorination. Potential end-products of anaerobic metabolism...
