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...

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

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...

Abstract:: Although legumes have been widely studied for their nitrogen-fixing ability, it is uncertain to what extent legume cover crops achieve their nitrogen-fixing potential under the climatic conditions encountered in western Oregon. Furthermore, it is unknown what factors control the proportions of legume cover crop N that are either sequestered into...

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,...

Creator:: Yeager, Chris M.
Abstract:: A number of bacterial species are capable of degrading the widespread environmental pollutant trichloroethylene (TCE) via aerobic cometabolism, but cytotoxic effects that can debilitate the microorganism often accompany this transformation. In this dissertation the effects of TCE degradation on the well-studied, toluene-oxidizing bacterium Burkholderia cepacia G4 were investigated at the...
