Abstract:

The present invention relates to a biological method for dechlorinating polychlorinated biphenyls (PCBs) by inoculating a polychlorinated biphenyl containing sample with PCB dechlorinating anaerobic methanogenic granules. The granules are made by coculturing particles of a PCP-dechlorinating methanogenic microbial consortia and a PCB-dechlorinating microorganism under anaerobic conditions in an upflow anaerobic sludge blanket (USAB) reactor.
