Biodegradation of methyl tert-butyl ether (MTBE) and its breakdown products by propane and iso-pentane grown Mycobacterium vaccae and Graphium sp. : cometabolism, inhibition, kinetics, and modeling

Creator:: Martínez-Prado, Maria Adriana
Abstract:: Mycobacterium vaccae JOB5 and Graphium sp. were studied to evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its metabolites after growth on two different alkanes, propane and iso-pentane. Both cultures were capable of cometabolizing MTBE and the metabolites, tert-butyl formate (TBF) and tert-butyl alcohol (TBA). MTBE, TBF, and...

A computational-based methodology for the rapid determination of initial AP location for WLAN deployment

Creator:: Altamirano, Esteban
Abstract:: The determination of the optimal location of transceivers is a critical design factor when deploying a wireless local area network (WLAN). The performance of the WLAN will improve in a variety of aspects when the transceivers' locations are adequately determined, including the overall cell coverage to the battery life of...

Metabolic uncoupling of Shewanella oneidensis MR-1, under the presence of excess substrate and 3,3’,4’,5 tetrachlorosalicylanilide

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...

Anaerobic reductive dechlorination of TCE and TCFE in TCE contaminated sediments : enhanced bioremediation and bioaugmentation

Creator:: Lee, Jae-Hyuk
Abstract:: This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

Uptake and metabolism of polycyclic aromatic hydrocarbons by the marine alga Acrosiphonia coalita

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...

Computational and experimental investigation of steady flow fields, turbulence, and hemodynamic wall stresses in patient-specific abdominal aortic aneurysm models

Creator:: Edgar, Erik S.
Abstract:: Steady flow fields and flow-induced wall stresses have been evaluated by experimental measurements and computational fluid dynamics (CFD) analysis in a series of patient-specific abdominal aortic aneurysm (AAA) models, over a range of Reynolds numbers (Re) from 125 to 3000 (500 to 3000 for CFD). Experimental methods used particle image...

Physiological response of Nitrosomonas europaea to oxytetracycline, chromium, and silver

Creator:: Schaerer, Morgan A.
Abstract:: Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....

Interactions between natural organic matter and gold nanoparticles stabilized with different organic capping agents

Creator:: Stankus, Dylan Paul
Abstract:: The adsorption of natural organic matter (NOM) to the surfaces of natural colloids and engineered nanoparticles is known to strongly influence, and in some cases control, their surface properties and aggregation behavior. As a result, the understanding of nanoparticle fate, transport and toxicity in natural systems must include a fundamental...

Transcriptional and physiological response of Nitrosomonas europaea to inhibition by chlorinated aromatics and heavy metals

Creator:: Sandborgh, Sean C.
Abstract:: This research investigates the physiological and transcriptional responses of Nitrosomonas europaea when exposed to chlorinated aromatic compounds and heavy metals under varying environmental conditions. It was found that transcriptional responses of identified sentinel genes correlate well with nitrification inhibition. Sorption of metals to biomass was also investigated and found not...

Microbial enhanced oil recovery : a pore-scale investigation of interfacial interactions

Creator:: Armstrong, Ryan T.
Abstract:: Current oil production technologies recover only about one‐third to one‐half of the oil originally present in an oil reservoir. Given current oil prices, even a modest increase in oil recovery efficiency is fiscally attractive. One novel approach to increase oil recovery efficiency is a process called microbial enhanced oil recovery...
