多氯联苯(PCBs)是对一类人工合成的有机化合物的统称,中国于1965年开始生产多氯联苯,1974年已经禁止生产此类产品。由于多氯联苯具有稳定的化学性质,其曾经被广泛应用于多种工业产品之中。多氯联苯现在已被证实对环境和人体健康有极大不良影响。大量的多氯联苯处理方法已被广泛的研究。文章对多氯联苯的生物降解研究的发展进行了综述,总结了PCBs微生物降解厌氧脱氯和有氧开环氧化的机制和影响因素,指出了进一步研究的方向。
多氯聯苯(PCBs)是對一類人工閤成的有機化閤物的統稱,中國于1965年開始生產多氯聯苯,1974年已經禁止生產此類產品。由于多氯聯苯具有穩定的化學性質,其曾經被廣汎應用于多種工業產品之中。多氯聯苯現在已被證實對環境和人體健康有極大不良影響。大量的多氯聯苯處理方法已被廣汎的研究。文章對多氯聯苯的生物降解研究的髮展進行瞭綜述,總結瞭PCBs微生物降解厭氧脫氯和有氧開環氧化的機製和影響因素,指齣瞭進一步研究的方嚮。

Polychlorinated biphenyls(PCBs) belong to a broad family of man- made organic chemicals known as chlorinated hydrocarbons. PCBs were domestically manufactured from 1965 until their manufacture was banned in 1974. Due to their stable chemical nature, PCBs were used in hundreds of industrial and commercial applications. PCBs have been demonstrated to destruct the environment, cause a variety of adverse health effects. Lots of PCBs disposal methods have been widely researched. This pa- per reviewed the developments of PCBs biodegradation research, summarized the effect of aerobic oxidation and anaerobic dechlo- rination and pointed out the directions of further studies.
