Abstract

This paper generalizes knowledges acquired so far on bio-remediation of PCB. Aerobic PCB decomposition using soil bacteria generally goes through introduction of O2 into second and third orders of a biphenyl ring, ring cleavage, and hydrolysis, and generates benzoate finally. PCB that is decomposed in this 2, 3-dioxygenaze path requires at least one of the second and third orders to be open. The decomposition through this path becomes difficult when the number of displaced Cl increases, and PCB with Cl displaced in only one of the rings decomposes more easily than PCB with the same number of Cl in both rings. A group in GE, Inc. has searched for two kinds of bacteria stocks that introduce O2 preferentially into the third and fourth orders. These stocks decompose third and fourth ordered open high-chlorine PCB. Groups in GE, Inc. and other companies have isolated bacteria that dechlorinate PCB decreasingly under an anaerobic condition. These bacteria desorb metha-ordered chlorine. Discussions are being made on cloning of PCB decomposing genes, and breeding of decomposing bacteria that have wide PCB decomposing spectra. 22 refs., 8 figs., 2 tabs.
