ABSTRACT:
Disclosed is a method for the anaerobic microbial dechlorination of polychlorinated biphenyls (PCBs). Polyhalogenated ethenes are used to stimulate the growth and dechlorinating activity of PCB dechlorinating bacteria in a contaminated soil or sediment. This method may be further coupled with aerobic microbial degradation of PCBs for the complete destruction of PCBs in soils and sediments. Polyhalogenated ethenes are also used in growth media for the culturing of PCB dechlorinating bacteria.
