Influence of soil acidity upon nodulation and growth characteristics of Trifolium subterraneum L.

Creator:: Almendras, Angela S.
Abstract:: Previous research had identified four serogroups of Rhizobium trifolii indigenous to Abiqua soil (fine, mixed, mesic, Cumulic Ultic Haploxerolls). Nodulation of subterranean clover (Trifolium, subterraneum L.) by two of the serogroups, 6 and 36, was influenced by the application of CaC0₃ to the soil. The studies described in this thesis...

Evaluation of bioluminescence as a measure of bacterial cell density in porous media

Creator:: Uesugi, Sandra L.
Abstract:: Salicylate-induced, lux gene dependent bioluminescence was measured using a cooled charge-coupled device (CCD) camera to evaluate its potential as a quantitative measurement of cell density of Pseudomonas fluorescens HK44 in porous media. The CCD camera was able to detect bioluminescence from cell densities between 1x10⁶ and 1x10⁸ cells/ml in both...

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,...

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...

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...

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...

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...

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...
