Formation and detoxification of reactive intermediates in the metabolism of chlorinated ethenes

Journal of Biotechnology, 2001
Short-chain halogenated aliphatics, such as chlorinated ethenes, constitute a large group of priority pollutants. This paper gives an overview on the chemical and physical properties of chlorinated aliphatics that are critical in determining their toxicological characteristics and recalcitrance to biodegradation.

Applicability of competitive and noncompetitive kinetics to the reductive dechlorination of chlorinated ethenes

Biotechnology and Bioengineering, 1998
Reductive dechlorination of chlorinated ethenes has typically been modeled using standard Michaelis-Menten kinetic equations, implying that each dechlorination step is catalyzed by a unique biological factor. An alternative kinetic model is based on the assumption that all steps are mediated by a single factor.

Sequential dehalogenation of chlorinated ethenes

Environmental Science & Technology, 1986
Reductive dehalogenation of tetra- and trichloroethene to cis- and trans-1,2-dichloroethene in microcosms simulating groundwater environment has previously been demonstrated. In this study, anoxic microcosms containing organic sediment and water were spiked to contain 5 mg/L of one of the following compounds: 1,1-dichloroethene (1,1-DCE), cis-1,2 ...

Effects of surfactants on the dechlorination of chlorinated ethenes

Environmental Toxicology and Chemistry, 2003
Abstract The influence of surfactants on a perchloroethene (PCE) dechlorinating mixed culture was investigated in laboratory experiments. Surfactants (Steol CS-330, Aerosol MA 80-I, alpha olefin sulfonate 14 to 16, Neodol 25-7, Tween 80, alkyl polyglycoside, C16TAB [trimethylammonium bromide], and sodium dodecyl sulfate) were evaluated ...

Partitioning of dissolved chlorinated ethenes into vegetable oil

Water Research, 2005
Food-grade soybean oil (SoyOil) has been used to enhance in situ anaerobic bioremediation at sites contaminated with chlorinated ethenes (CEs). The abiotic interactions of SoyOil with the CEs may be significant and need to be better understood. The oil: water partition coefficients (Kp) of dissolved CEs into SoyOil were measured in batch tests and ...
