ABSTRACT:
A method for bioremediation of hazardous wastes is disclosed. The method can be used for anaerobic treatment of a liquid or slurry hazardous waste stream (e.g., industrial wastewater or sludge) or for treatment of contaminated groundwater. Removal of halogenated (e.g., chlorinated) hydrocarbons, such as tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethane and similar xenobiotics is possible. The method involves biotransformation of (dehalogenation) halogenated hydrocarbons by means of natural methanogenic bacteria, Methanosarcina barkeri strain 227 and/or Methanosarcina vacuolata. These methanogens can accomplish cometabolism of chlorinated hydrocarbons during metabolism of a primary substrate such as hydrogen-carbon dioxide, methanol, methylamine, dimethylamine, trimethylamine and acetate. Reductive dechlorination, energy conservation and control of air pollution are accomplished.
