Chloroform was dechlorinated by ptme cultures of Methanosarcina sp. strain DCM and Methanosarcina mazei S6. The initial dechlorination product of chloroform was dichloromethane, accounting for about 70 percent of added chloroform. The product of dichloromethane, chloromethane was detected consistently at trace levels but could not be accurately quantified. The production of C02 from [ H1] - chloroform and the absence of CH imply that reaction mechanisms other than reductive dechlorination alone are important [92]. Degradation of dichloromethane by oxidation via phosgene or alcohols was proposed previously, for methanogenic systems [13].
