Biodegradability of commercial polychlorobiphenyl mixtures (Kaneclors, KC 200 to KC 500) and their metabolic products by Acinetobacter sp. strain P6 were studied by gas chromatography-mass spectrometry analysis. KC 200 (primarily dichlorobiphenyls) rapidly degraded after 4 h of incubation with the P6 resting cells, showing predominant accumulation of monochlorobenzoic acids. KC 300 (primarily trichlorobiphenyls) were also degraded after 4 h of incubation, producing various metabolic intermediates such as mono- and dichlorobenzoic acids, dihydroxy biphenyl compounds with two and three chlorines, and the ring meta-cleavage compounds with two and three chlorines. KC 400 (primarily tetrachlorobiphenyls) were also susceptible to biodegradation by the same organism. Chlorobenzoic acids (chlorine number 1 to 3), dihydroxy compounds (chlorine number 2 to 4), and the ring meta-cleavage compounds (chlorine number 2 to 3) were observed as the products from KC 400. In addition to such products, a large amount of unknown compounds with two chlorines in the molecule, which can be derived from 2,3,2',3' - or 2,3,2',5'-tetrachlorobiphenyls or both, accumulated. In contrast to KC 200, KC 300, and KC 400, KC 500 (primarily pentachlorobiphenyls) were resistant to degradation and hardly metabolized. Only dihydroxy compounds of certain pentachlorobiphenyls were detected.
