The release of polychlorinated biphenyls (PCBs) into the environment has caused public concern. PCBs are know known to be susceptible to biodegradation; PCBs in the Hudson river have been shown to be extensively dechlorinated, but the rate of dechlorination in anaerobic environments have been slow, over months or years. This study tested the effects of PCB concentration and sediment supplementation with 2,3,6-trichlorobiphenol, on the rate of PCB dechlorination and methanogenesis. The rates of meta dechlorination in sediment supplemented cultures were measured in the laboratory, including both the rate per bacterial cell and the rate of methanogenesis when dechlorination increases. 24 refs., 3 figs., 1 tab.
