Capacity of enzymes of the biphenyl/chlorobiphenyl pathway, especially biphenyl dioxygenase of two PCB degrading bacteria, Burkholderia sp. LB400 and Comamonas testosteroni B-356, to metabolize ortho-substituted hydroxybiphenyls was tested. Compounds found among plant products of PCB metabolism, carrying chlorine atoms on the hydroxyl-substituted ring were hydroxylated on the non-substituted ring

Byla studována schopnost bakteriálních enzymů biphenylové/chlorobifenylové dráhy, zejména bifenyldioxygenasy ze dvou PCB-degradujících bakterií, Burkholderia sp. LB400 a Comamonas testosteroni B-356, metabolizovat ortho-substituované hydroxybifenyly vytvářené z PCB rostlinami. Sloučeniny nalezené mezi produkty rostlinného metabolismu PCB nesoucí atom chloru na kruhu se substitucí hydroxylem jsou bakteriálními enzymy hydroxylovány na nesubstituovaném kruhu
