Correlation of NE 1545 expression and cell size in Nitrosomonas europaea exposed to a suite of aromatic hydrocarbons

Creator:: Gilroy, Caslin Anne
Abstract:: Ammonia oxidizing bacteria, including Nitrosomonas europaea, are inhibited by aromatic hydrocarbons which can be found in wastewater treatment plants. In recent studies, changes have been observed in N. europaea cell size upon exposure to benzene, but not toluene. Additionally, NE 1545, a gene proposed to be involved in fatty acid...

Bench-scale study for the bioremediation of chlorinated ethylenes at Point Mugu Naval Air Weapons Station, Point Mugu California, IRP Site 24

Creator:: Keeling, Matthew Thomas
Abstract:: Laboratory scale microcosm studies were conducted using site specific groundwater and aquifer solids to assess the feasibility of stimulating indigenous microorganisms in-situ to biologically transform Trichloroethylene (TCE) and its lesser chlorinated daughter products dichloroethylene (DCE) and vinyl chloride (VC). Three different treatments were conducted to determine the best approach for...

Modeling cometabolic transformation of a CAH mixture by a butane utilizing culture

Creator:: Mathias, Maureen Anne
Abstract:: The goal of this research was to mathematically simulate the ability of bioaugmented microorganisms to aerobically cometabolize a mixture of chlorinated aliphatic hydrocarbon (CAH) compounds during in-situ treatment. Parameter values measured from laboratory experiments were applied to the transport model with biotransformation processes included. In laboratory microcosm studies, a butane-grown,...

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...

Aerobic degradation of chlorinated ethenes by Mycobacterium strain JS60 in the presence of organic acids

Creator:: Blatchford, Christina
Abstract:: This study evaluated the potential of the aerobic Mycobacterium strain JS6O to grow on a variety of organic acid substrates, and the possible effects an organic acid would have on the degradation rate of vinyl chloride (VC). A series of batch growth tests were designed to determine the time it...

Aerobic cometabolism of 1,1,1-trichloroethane and 1,1-dichloroethene by a bioaugmented butane-utilizing culture in a continuous flow column

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...

Microcosm studies of bioaugmentation with a butane-utilizing mixed culture : microbial community structure and 1,1-DCE cometabolism

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...

Aerobic cometabolism of trichloroethylene and cis-dichloroethylene in propane-fed microcosms from the McClellan Air Force Base

Creator:: Timmins, Brian
Abstract:: This thesis focused on using microcosms to better understand the aerobic cometabolic processes of TCE and cis-DCE transformation that occurred during a Cometabolic Air Sparging (CAS) demonstration at McClellan Air Force Base. The microcosms were created with groundwater and aquifer materials from the demonstration site. Concentrations of compounds in the...
