Cometabolism of 1,4-Dioxane and Chlorinated Aliphatic Hydrocarbons by Pure Cultures of Rhodococcus rhodochrous 21198 and Mycobacterium ELW1 and in Groundwater Microcosms Fed Isobutane and Isobutene as Growth Substrates

Creator:: Krippaehne, Krysta J.
Abstract:: 1,4-dioxane and chlorinated aliphatic hydrocarbons (CAHs) such as trichloroethylene (TCE) and 1,1-dichloroethene (1,1-DCE) are hazardous compounds commonly found in soil and groundwater. Bioremediation through aerobic cometabolism is a potential option for the remediation of these contaminated sites. The purpose of this study was to examine the use of different primary...

The Effect of Oxygen and Salinity Conditions on Soluble Metabolic Product Formation by Methylomicrobium buryatense 5GB1

Creator:: Cameron, Marina R.
Abstract:: Methanotrophic bacteria are promising means of producing value-added products as they have the ability to transform methane under atmospheric temperature and pressure. Efforts to develop methanotrophs to produce value-added products are hoped to incentivize a decrease in methane flaring operations. The data collected during this study was used to inform...

Inhibition of Organohalide-Respiring Bacteria by Carbon Tetrachloride and Chloroform

Creator:: Ehret, Emma L.
Abstract:: Despite decades of cleanup efforts, chlorinated solvents are some of the most common groundwater and subsurface contaminants of the industrialized world. These compounds include chlorinated ethenes (CEs) such as trichloroethene (TCE) and chlorinated methanes (CMs) such as carbon tetrachloride (CT). Dehalococcoides mccartyi belongs to a class of microorganisms called organohalide-respiring...

Experimental demonstration and modeling of aerobic cometabolism of 1,4-dioxane by isobutane-utilizing microorganisms in aquifer microcosms

Creator:: Rolston, Hannah M.
Abstract:: 1,4-dioxane, a probable human carcinogen at low (< 1ppb) concentrations, has emerged as a groundwater contaminant due to its historical use as a stabilizer for the chlorinated solvent 1,1,1-trichloroethane. Aerobic cometabolism, the use of a primary substrate to induce the production of microbial enzymes that fortuitously degrade other compounds, is...

Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites

Creator:: Schrlau, Jill E.
Abstract:: The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were...

Transformation of Carbon Tetrachloride and Chloroform by Trichloroethene Respiring Anaerobic Mixed Cultures and Supernatant

Creator:: Vickstrom, Kyle E.
Abstract:: Carbon tetrachloride (CT) and chloroform (CF) were transformed in batch reactor experiments conducted with anaerobic dechlorinating cultures and supernatant (ADC+S) harvested from continuous flow reactors. The Evanite (EV-5L) and Victoria/Stanford (VS-5L) cultures capable of respiring trichloroethene (TCE), 1,2-cis-dichloroethene (cDCE), and vinyl chloride (VC) to ethene (ETH) were grown in continuous...

Batch and Continuous Flow Column Studies of Methane Consumption and Methanol Production by Methylosinus Trichosporium OB3b and Methylomicrobium Buryatense 5GB1 Immobilized In Ca-Alginate and Agarose Hydrogels

Creator:: Molzahn, Paige
Abstract:: Two methanotrophs, M. trichosporium OB3b and M. buryatense 5GB1, were encapsulated using two methods to investigate the potential of methane conversion for biofuel production. Ca-alginate and low melt agarose were used to immobilize the methanotrophs for batch and continuous flow column testing. Varying protein concentrations, residence times, and immobilization methods...

Kinetic analysis of the aerobic degradation of chlorinated ethenes by the mycobacterium ELW-1 and chlorinated ethanes and ethenes by rhodococcus rhodochrous ATCC® 21198™

Creator:: Rich, Stephanie L.
Abstract:: Bioremediation of chlorinated ethenes by the augmentation of contaminated soils with microorganisms is a proposed method of reducing contaminant concentrations in groundwater. To determine the viability of using ELW-1 or R. rhodochrous for groundwater remediation, kinetic analyses of transformation rates must be performed. The focus of this research was to...

Effects of silver ions and nanoparticles on suspended cells and biofilms of Nitrosomonas europaea

Creator:: Barker, Leila Kelly
Abstract:: Silver nanoparticles are increasingly being incorporated into consumer products due to their broad-spectrum antimicrobial properties. The resulting influx of silver nanoparticles into wastewater may pose a threat to bacteria involved in biological wastewater treatment. Ammonia-oxidizing bacteria, which convert ammonia to nitrite in the first step of nitrification, are highly sensitive...

The effect of silver ions and nanoparticles on biofilms and planktonic cultures of Nitrosomonas europaea

Creator:: Giska, Jonathan R.
Abstract:: Due to the effective antimicrobial properties of silver nanoparticles they represent a significant proportion of all consumer-‐related nanomaterials. The introduction of silver nanoparticles from these products into domestic and industrial wastewater streams poses potential complications for biological treatment systems. A critical component of biological treatment that is extremely sensitive to...
