Biphenyl-utilizing soil bacteria are ubiquitously distributed in the natural environment. They cometabolize a variety of polychlorinated biphenyl (PCB) congeners to chlorobenzoic acids through a 2,3-dioxygenase pathway, or alternatively through a 3,4-dioxygenase system. The bph genes coding for the metabolism of biphenyl have been cloned from several pseudomonads. The biochemistry and molecular genetics of PCB degradation are reviewed and discussed from the viewpoint of an evolutionary relationship.
利用联苯的土壤细菌广泛分布于自然环境中。它们通过2,3 - 双加氧酶途径或3,4 - 双加氧酶系统将多种多氯联苯（PCB）同系物共代谢为氯苯甲酸。编码联苯代谢的bph基因已从几种假单胞菌中克隆出来。本文从进化关系的角度对联苯降解的生物化学和分子遗传学进行了综述和讨论。
