An anaerobic microcosm study of TCE transformation by microbes stimulated from the Gilbert-Mosley site, Wichita, Kansas

Creator:: Pon, George
Abstract:: A mix-culture of methanogenic and sulfate-reducing bacteria was capable of degrading trichloroethylene (TCE) to dichloroethylene (DCE). The culture was incubated under anaerobic conditions within a soil sample taken from Gilbert-Mosley site, Wichita, Kansas. To stimulate the growth of indigenous bacteria, a carbon and energy source was added in this microcosm...

Continuous-flow and batch column studies of anaerobic carbon tetrachloride biotransformation on Hanford soil

Creator:: Niemet, Michael Richard
Abstract:: Continuous-flow and batch experiments were conducted with a column reactor system containing Hanford aquifer material in order to evaluate the potential of in-situ bioremediation of carbon tetrachloride (CT) at Hanford. The effectiveness of benzoate and acetate as primary substrates was considered. Nitrate and sulfate were potential electron acceptors. Transport experiments...

Kinetic and molecular effects of sulfate reduction on a dechlorinating culture under chemostat growth conditions

Creator:: Berggren, Dusty Rose V.
Abstract:: Chlorinated ethenes are common groundwater contaminants that may be treated through in-situ bioremediation. Relationships between the reducing environment, available electron donors and acceptors, reaction kinetics, and microbial community composition must be further understood to successfully engineer remediation schemes in the complex subsurface environment. This thesis work investigated the effect of...

Co-Encapsulation of Slow Release Substrates and Microbial Cultures in Alginate and Gellan Gum Beads to Promote the Co-metabolic Transformation of 1,4-Dioxane and Chlorinate Aliphatic Hydrocarbons

Creator:: Rasmussen, Mitchell T.
Abstract:: Methods were developed for the co-encapsulation of slow release compounds (SRC) with viable microbial cells in alginate and gellan gum hydrogel beads, for the in-situ aerobic cometabolic treatment of groundwater contaminated with mixtures of 1,4-dioxane and chlorinated aliphatic hydrocarbons, which will be referred to as contaminants of concern (CoC). The...

Cometabolism of Chlorinated Ethenes by Burkholderia vietnamiensis G4 Grown on Aromatic Substrates: Resting and Co-encapsulated Cell Kinetic Tests

Creator:: Saito, Alyssa M.
Abstract:: The cometabolic ability of Burkholderia vietnamiensis G4 grown on aromatic substrates was first assessed by resting suspended cells, and subsequently for cells encapsulated with and without slow release compounds (SRCs). In Chapter 3, benzyl alcohol was assessed as a food-grade growth substrate for promoting cometabolism of trichloroethene (TCE), via the...

Evaluation in a Physical Aquifer Model the Long-Term Performance of a Permeable Reactive Bio-Barrier Packed with Co-encapsulated Gellan Gum Beads for the Bioremediation of Chlorinated Compounds and Co-Contaminants

Creator:: Wortkoetter, Jacob
Abstract:: Chlorinated solvents are a class of widespread groundwater contaminants that are toxic, carcinogenic, and difficult to remediate at low concentrations. 1,4-dioxane, a suspected carcinogen, is often a co-contaminant found in mixtures of chlorinated solvent plumes. In-situ bioremediation methods of degrading these chemicals through aerobic cometabolism have shown promise. Permeable Reactive...

Aerobic Cometabolism of 1,4-Dioxane and cis-Dichloroethylene by Gellan Gum and Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads Co-Encapsulated with Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Batch, Column, and Toxicity Studies

Creator:: Conway, Sean P.
Abstract:: 1,4-Dioxane (dioxane) and cis-dichloroethylene (cDCE) are compounds commonly found in industrial cleaning and degreasing agents that are frequently present as groundwater contaminants. In an effort to develop a more effective treatment method for these compounds, hydrogel beads were fabricated with either gellan gum or a combination of polyvinyl alcohol (PVA)...

Creator:: Bailey, Kestrel
Abstract:: CisCis-Dichloroethylene (ciscis-DCE), 1,1,1-Trichloroethane (1,1,1-TCA), and 1,4-Dioxane (1,4-D) are chlorinated solvents used as solvents and degreasers in industrial cleaning agents that have become common groundwater contaminants. To develop an effective treatment method for these compounds, polyvinyl alcohol (PVA) and sodium alginate (SA) hydrogel beads were co-entrappcapsulated with Rhodococcus rhodochrous Strain ATCC...

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...

Abiotic and biological transformation of TBOS and TKEBS, and their role in the biological transformation of TCE and c-DCE

Creator:: Vancheeswaran, Sanjay
Abstract:: At Site-300, Lawrence Livermore National Laboratory (LLNL), CA, trichloroethene (TCE) is present along with tetraalkoxysilanes such as tetrabutoxysilane (TBOS) and tetrakis(2-ethylbutoxy) silane (TKEBS), as subsurface contaminants. Intrinsic transformation of TCE to cis-dichloroethene (c-DCE) was observed in the groundwater at locations co-contaminated with TBOS or TKEBS. Attenuation of TBOS and TKEBS...
