Creator:: Schlenk, Daniel K.
Abstract:: Aquatic animals are exposed to a variety of natural and anthropogenic xenobiotics. Biotransformation of xenobiotics was examined in three aquatic animals: a primitive mollusc (chiton); a shellfish which is an important human food source (oyster); and, a lower vertebrate model for toxicological studies (rainbow trout). Since digestive glands of Cryntochiton...

Creator:: Maremanda, Bhargavi
Abstract:: The transformation of 1,1,1 -trichioroethane (1,1,1 -TCA) and 1,1 -dichioroethene (1,1 - DCE) was evaluated in a continuous flow column reactor using a mixed culture that grew on butane. The column was packed with aquifer materials and groundwater obtained from the in-situ bioremediation test site at Moffett Field, CA. The...

Creator:: Lim, Hee Kyung
Abstract:: The 1,1-dichloroethene (1,1-DCE) cometabolic transformation abilities of indigenous and bioaugmented microorganisms were compared in microcosms constructed with groundwater and aquifer solids from the Moffett Field site, CA. Microbial community structure in the microcosms and possible community shifts due to 1,1-DCE transformation stress was evaluated by terminal restriction fragment length polymorphism...

Creator:: Tejasen, Sarun
Abstract:: The aerobic transformation of TCE and cis-DCE by a tetrabutoxysilane-grown microorganism (Vancheeswaran et al., 1999) led to the investigation of novel substrates, including benzyl alcohol, for promoting cometabolism. The culture grew on carboxylic compounds and alcohols, but did not grow on formate, methanol, methane, propane, butane, ethylene, benzene, toluene, or...

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

Creator:: Hardardt, Elizabeth Ann
Abstract:: This work sought to characterize a link between Vitamin C and nitroglycerin at the level of enzymatic bioactivation. Before we could proceed, we needed to develop a method that sensitively and selectively identified the product of bioactivation, nitrite. We successfully adapted traditional diaminonaphthalene derivatization with the use of stable isotope...
