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...

Molecular and Kinetic Characterization of Anammox Bacteria Enrichments and Determination of the Suitability of Anammox for Landfill Leachate Treatment

Creator:: Sultana, Sharmin
Abstract:: Anaerobic ammonium oxidation (anammox) has recently appeared as a promising approach for removing nitrogen from landfill leachates because it requires less oxygen and no organic carbon compared to traditional nitrification-denitrification system, and it produces low sludge volumes, thereby reducing operating and biological sludge disposal costs by over 60%. Anammox bacteria...

Inhibition of the ammonia oxidizing bacteria Nitrosomonas europaea by the emerging contaminant triclosan

Creator:: Hughes, Jamie L.
Abstract:: Identifying the inhibition of ammonia oxidizing bacteria (AOB) by emerging organic contaminants is crucial due to the importance of AOB in wastewater treatment, the widespread use of antibacterial agents such as triclosan (TCS) in consumer products, and the sensitivity of N. europaea to inhibitors. Triclosan inhibition of nitrification by AOB...

Genome-Scale Metabolic Reconstruction and Analysis of a Pure Culture Anaerobic Digester

Creator:: Kirkendall, Tyler M.
Abstract:: Anaerobic digestion is a biological process in which organic matter is decomposed by a community of microbes in the absence of oxygen. The end product of anaerobic digestion is biogas, composed of methane and carbon dioxide, which is often recovered and used to generate energy. Commonly, biogas is not produced...

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...

Evaluation of copper removal from stormwater runoff using compost and Apatite II™

Creator:: Silvertooth, Jason R.
Abstract:: Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...

Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

Creator:: Provolt, Justin J.
Abstract:: Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...

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...

Anaerobic co-digestion of acid whey and sewage sludge for enhanced renewable energy production

Creator:: Cole, Emerson
Abstract:: Acid whey is the largest byproduct of the dairy industry but to date has few useful applications and is frequently discarded as a result. However, acid whey has a high carbon content, making it a suitable co-substrate for anaerobic co-digestion with raw sewage sludge. The synergistic effect of co-digestion has...
