Aerobic Vinyl Chloride Metabolism in Groundwater Microcosms by Methanotrophic and Etheneotrophic Bacteria.

Vinyl chloride (VC) is a carcinogen generated in groundwater by reductive dechlorination of chloroethenes. Under aerobic conditions, etheneotrophs oxidize ethene and VC, while VC-assimilators can use VC as their sole source of carbon and energy. Methanotrophs utilize only methane but can oxidize ethene to epoxyethane and VC to chlorooxirane.

Contamination of groundwater with vinyl chloride (VC), a known human carcinogen, is a common environmental problem at plastics manufacturing, dry cleaning, and military sites. At many sites, there is the potential to cleanup VC groundwater plumes with aerobic VC-oxidizing microorganisms (e.g.
