Protection of Nitrosomonas europaea from Silver Nanoparticle-Induced Inhibition through a Two-Step, Magnesium-Facilitated Mechanism

Creator:: Anderson, Joseph W.
Abstract:: The inhibitory effects of (Ag⁺) and silver nanoparticles (Ag NP) 3-5 nm in diameter (stabilized with polyvinylpyrrolidone (PVP)) and 20 nm (stabilized with citrate) on nitrification rates of the model ammonia-oxidizing bacteria (AOB) Nitrosomonas europaea were investigated. Experimental solutions contained HEPES buffer and ammonia (NH₃) in the presence and absence...

Aerobic cometabolism of chloroform by butane and propane grown microorganisms from the Hanford subsurface

Creator:: Kim, Young
Abstract:: Batch microcosm studies were carried out to screen for microorganisms from the subsurface of Hanford DOE site that could cometabolically transform chloroform (CF) under aerobic conditions. The potential need for CF bioremediation at the Hanford site has resulted from the large release of carbon tetrachloride (CT) to the subsurface, of...

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 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...

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:: Bartow, Shannon M.
Abstract:: The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...

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...

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,...

Aerobic biotransformation of chlorinated aliphatic hydrocarbons by a benzyl alcohol grown mixed culture : cometabolism, mechanisms, kinetics and modeling

Creator:: Tejasen, Sarun
Abstract:: The aerobic transformation of TCE and cis-DCE by a tetrabutoxysilane-grown microorganism (Vancheeswaran et al., 1999) led to the investigation of novel substrates, including benzyl alcohol, for promoting cometabolism. The culture grew on carboxylic compounds and alcohols, but did not grow on formate, methanol, methane, propane, butane, ethylene, benzene, toluene, or...

Bioaugmentation of Pure and Enriched Cultures Fed Multiple Primary Substrates to Aerobically Cometabolize a Mixture of Chlorinated Solvents and 1,4-dioxane in Microcosms Containing Groundwater from a Department of Defense Site

Creator:: Laurance, Jon C.
Abstract:: Chlorinated solvents are common groundwater pollutants that often exist as mixtures resulting from the use of multiple solvents and their transformation into chlorinated daughter products. These sites are often co-contaminated with the solvent stabilizer 1,4-dioxane (1,4-D), which is not treated by traditional chlorinated solvent remediation techniques. Both 1,4-D and chlorinated...
