Bacterial degradation of vinyl chloride

Identification of abiotic and biotic reductive dechlorination in a chlorinated ethene plume after thermal source remediation by means of isotopic and molecular biology tools

“…cDCE is hence often found to accumulate in the subsurface. Microbial oxidation might also take place, particularly in the case of cDCE and VC (Hartmans et al, 1985;Bradley andChapelle, 1998, Bradley andChapelle, 2000). Despite their presence in the subsurface, microorganisms may display a low activity, are sometimes inactive or are even dormant (Meckenstock et al, 2015), which may additionally hinder reductive dechlorination.…”

Anaerobic dechlorination of tetrachloromethane and 1,2-dichloroethane to degradable products by pure cultures of Desulfobacterium sp. and Methanobacterium sp.

“…A few of these compounds, generally with a low level of chlorination, are subject to aerobic degradation [ [2][3][4][5][6][7] or transformation [8-10; see also 11], and some of these degradative capacities can be applied to waste or water treatment [5,12,13]. But for the most part, the highly chlorinated solvents are subject only to anaerobic transformation [14][15][16][17][18][19][20][21][22].…”

Bacterial metabolism of 3-chloroacrylic acid

“…Micro-organisms utilizing chlorinated ethenes as sole carbon and energy source have been isolated only with monochloroethene (vinyl chloride) (Hartmans et al, 1985). The initial step in the aerobic transformation of chlorinated ethenes is generally assumed to be an epoxidation of the carbon-carbon double bond (Hartmans et al, 1989).…”

“…(Hartmans et al, 1985). Acetaldehyde and vinyl chloride (at 180 "C) and 1,3-dichIoropropene (at 210 "C) were assayed on a Packard 430 gas chromatograph fitted with a Porapak R column (Hartmans et al, 1985). CI-were determined colorimetrically (Bergmann & Sanik, 1957) or amperometrically (Hartmans et al, 1985).…”

“…COz concentrations were determined by analysing headspace samples on a gas chromatograph . (Hartmans et al, 1985). Acetaldehyde and vinyl chloride (at 180 "C) and 1,3-dichIoropropene (at 210 "C) were assayed on a Packard 430 gas chromatograph fitted with a Porapak R column (Hartmans et al, 1985).…”
