摘要 多氯联苯(Polychlorinated biphenyls,PCBs)是一种持久性有机污染物,对人类和自然环境具有很大的威胁,降解PCBs一直是研究的热点。在目前的研究方法中生物降解最具潜力,生物降解主要分为微生物降解、植物修复和微生物-植物共同修复3个方面。文章着重介绍了微生物降解PCBs菌株的分离,降解相关基因的克隆和改造;同时对植物修复,植物与微生物共同修复以及植物转基因修复进行了讨论。 As one of the persistent organic pollutants,polychlorinated biphenyls are harmful to the environment and hu-mans.Biodegradation is the most potential way to remove PCBs.Biodegradation can mainly be divided into microbial deg-radation,phytoremediation,plant and microbial combined remediation.Here,we introduced isolation of the PCBs-degrad-ing strains,cloning and modification of the related degradation genes.Additionally,on the other hand,the natural remedia-tion of plant,plant and microbial combined remediation,plant transgenic remediation were described.
