六氯苯微生物降解研究进展

摘要

Microbial degradation has become the key topic and frontiers of the research field of hexachlorobenzene (HCB) pollution control. The structure, physical and chemical properties, source and hazard of HCB are briefly introduced,and its potential biodegradability is also analyzed. The aerobic and anaerobic degradation of HCB is systematically reviewed and summarized from following aspects: sources of HCB-degrading strains, degradation pathways, influencing factors,ect. Moreover,the future research orientation of microbial degradation of HCB is proposed in this paper.%微生物降解已经成为当前六氯苯环境污染治理研究的重点和前沿.介绍了六氯苯的结构、物理化学性质、来源及其危害,分析了其微生物降解的可行性,从降解菌群的来源、降解途径及降解的影响因素等方面,对六氯苯的微生物好氧降解和厌氧降解进行了系统地归纳和总结,同时对今后六氯苯微生物降解的研究方向进行了展望.
