A model for the prediction of biologically mediated reductive dechlorination pathways

Creator:: Cozza, Cynthia L.
Abstract:: The environment has been exposed to a number of hazardous chlorinated organic compounds. These compounds may be anaerobically biotransformed by sequential reductive dechlorination reactions in which the chlorine atoms are replaced with hydrogen atoms. Because reductive dechlorination processes may occur very slowly in the environment and chlorine position affects the...

A kinetic approach for the determination of sorption rate constants using a column-type reactor

Creator:: Patrier, Lionel
Abstract:: A Langmuir sorption model incorporating a second step of irreversible absorption was applied to a model soil system. The column was packed with cellulose triacetate; pulse and step input tests with 3,4-dichlorophenol were performed; the effluent concentration was measured by electron capture detector gas chromatography and sorption rate constants were...

Startup and performance of a gas-permeable-membrane-supported (GPMS) biofilm system using a mixed culture of methylotrophs to degrade methylene chloride, chloroform, and carbon tetrachloride

Creator:: Ely, Roger L.
Abstract:: The methane monooxygenase (MMO) enzyme, used by methylotrophs to oxidize methane, has been shown to possess quite broad substrate specificity, being able to oxidize many organic compounds including n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and heterocyclic compounds. In this research, it was sought to determine whether a gas-permeable-membrane-supported (GPMS) biofilm...

Development of a method to elucidate biodegradation pathways of chlorinated one and two carbon compounds using a gas-permeable-membrane-supported methylotrophic biofilm

Creator:: Ryan, Kelly M.
Abstract:: A gas-permeable-membrane-supported (GPMS) biofilm consisting of methylotrophic bacteria was effective in degrading chlorinated methanes, ethanes, and ethenes. The biofilm was developed on a gas-permeable fabric (Goretex, W.L.Gore & Associates, Elkton, Maryland) that divided a reactor vessel into a liquid compartment and a gas compartment. Goretex is a nylon-backed teflon mesh...

The development of a gas-permeable-membrane-supported (GPMS) biofilm reactor for the combined anaerobic/aerobic treatment of polychlorinated biphenyls

Creator:: Polonsky, Jon D.
Abstract:: A continuous flow, gas-permeable-membrane-supported (GPMS) biofilm reactor was developed to facilitate the treatment of polychlorinated biphenyls (PCBs). The GPMS biofilm reactor consisted of a cylindrical glass vessel made up of three compartments: the gas, liquid and headspace compartments. A gas-permeable membrane separated the bottom gas compartment from the liquid compartment....

A method of PCB metabolite determination in anaerobic freshwater sediments using a upflow anaerobic biofiltration process (ANBIOF)

Creator:: Low, Edmond J.
Abstract:: The biodegradation of five polychlorinated biphenyls (PCBs) by Hudson River and Silver Lake sediments was studied using gas chromatography with electron capture detection (GC/ECD) and gas chromatography with mass spectrometry (GC/MS) analyses. Methanogenic sediments from the Hudson River and Silver Lake were used to inoculate four anaerobic filter reactors. The...

Measurement of the rates of reductive dechlorination of chlorinated phenols

Creator:: Nicholson, David K.
Abstract:: Knowledge of a compound's degradation pathway is crucial to the assessment of risk at contaminated sites. Pentachlorophenol and its metabolic products can serve as model compounds to study the fate and transport of halogenated aromatic compounds in the environment. Acclimation of anaerobic sewage sludge to pentachlorophenol produced a microbial consortium...

Down-borehole permeable barrier reactor : primary substrate selection for aerobic dichlorophenol degradation

Creator:: Kaslik, Peter J.
Abstract:: In situ bioremediation of pentachlorophenol-contaminated ground water in a sequential anaerobic-aerobic down borehole permeable barrier reactor requires a non-toxic primary substrate for dichlorophenol cometabolism. Serum bottle tests comparing the effectiveness of eight primary substrates for aerobic dichlorophenol degradation showed phenol to be the most effective followed by imitation vanilla flavoring,...
