微生物降解多环芳烃的影响因素及机理研究进展

多环芳烃是一类普遍存在的环境污染物，微生物的降解是PAHs去除的主要途径。介绍了多环芳烃性质及目前国内外研究状况，以及降解多环芳烃的微生物，阐述了三大因素：微生物活性、基质和环境因予等对微生物降解多环芳烃的影响，微生物降解多环芳烃的机理；并对今后的几个研究发展方向进行了展望。

Research progress in influencing factors and mechanism ofmicrobial degradation of polycyclic aromatic hydrocarbon

Abstract: PAHs are a class of widesp read pollutants in the environment, microbial degradation is the main way of removing PAH. This article p resented the nature of the polycyclic aromatic hydrocarbon and the research sit2 uation at home and abroad, and the microbial of degradating polycyclic aromatic hydrocarbon, analyzed the three factors, such asmicrobial activity, and matrix environmental factors, the effects ofmicrobial degradatation on poly2 cyclic aromatic hydrocarbon, and the mechanism of microbial degradation of polycyclic aromatic hydrocarbon. Fi2 nally, the author forecasted a few research directions of future development.
