The study investigates aspects of PCB metabolism by a hairy root culture Solanum nigrum L. (clone SNC-90) in vitro. Standard conditions were established for efficient, up to 72% PCB conversion (22 individual PCB congeners examined in commercial mixture Delor 103, 5 g fresh biomass in 100 ml media shaken with 5 mg PCB fior 14 days). The conversion products formed from three monochlorobiphenyls were monohydroxychlorobiphenyls and dihydroxychlorobiphenyls, while six dichlorobiphenyls yielded different monohydroxydichlorobiphenyls. Efficiency of the transformation of individual PCB congeners was evaluated together with phytotoxic effect on the clone SNV-90. Major metabolites of monocholorobiphenyls analysed after extraction from biomass were hydroxylated at the position 4, and 4', respectively.
