Characterization of anaerobic perchloroethylene dehalogenation activity at various substrate and perchloroethylene concentrations

Research was undertaken to characterize anaerobic perchloroethylene (PCE) dehalogenation activity of microorganisms at various substrate and PCE concentrations. The concentrations of substrate, chlorinated ethylenes, and metabolic products such as methane, acetate, propionate, butyrate, hydrogen, and formate were monitored. The apparent relationship between major metabolic activities and dehalogenation was determined.
