利用氯酚的好氧黄杆菌降解五氯酚的途径。由PCP转化为四氯对对苯二酚（TCH）引发。18O标记实验表明，在第一次脱氯过程中，一个羟基取代了PCP环上4号位置的氯，这涉及水解反应。然后对TCH进行两次还原脱氯，首先得到三氯对苯二酚（TrCH），然后得到2,6-二氯对苯二酚（DCH）。因此，黄杆菌分解PCP的初始步骤是：PCP→TCH→TrCH。
The pathway employed for pentachlorophenol (PCP) degradation by an aerobic, chlorophenol-utilizingFlavobacteriumsp. was initiated by conversion of PCP to tetrachloro-p-hydroquinone (TCH).18O labelling experiments demonstrated that the first dechlorination, where a hydroxyl replaced the chlorine at PCP ring position number 4, involved a hydrolytic reaction. Then two reductive dechlorinations of TCH followed to yield firstly trichlorohydroquinone (TrCH) and then 2,6-dichlorohydroquinone (DCH). Thus, the initial steps in catabolism of PCP by theFlavobacteriumwere: PCP → TCH → TrCH.
