Natural mixed-microbial populations in lake water were found capable of oxidizing 2-chlorobiphenyl but not 2,4'-dichlorobiphenyl. No evidence was found to indicate that these populations were able to oxidize a PCB mixture 54% chlorine by weight. Oxidation of 2-chlorobiphenyl resulted in the accumulation of two biotransformation products, chlorobenzoic acid and chlorobenzoylformic acid (chlorophenylglyoxylic acid). The results indicate that biodegradation of PCB congeners may result in the accumulation of environmentally stable chlorinated biotransformation products in aquatic environments.
