多环芳烃的微生物降解机制研究进展

摘要

多环芳烃是环境中最常见且最难降解的有机污染物之一。通过微生物降解使环境中的多环芳烃低毒化或无毒化是当今环境修复的研究热点之一。以萘和菲为研究对象，论述了多环芳烃的微生物降解机制，并阐述了生命组学新技术在多环芳烃降解机制研究中的应用，为深入探讨多环芳烃的微生物降解及转化机制奠定了理论基础。%Polycyclic aromatic hydrocarbons(PAHs)are one of the common and the most refractory organic pollutants in the environment.Nowadays,low-toxicity or non-toxicity of PAHs by microbial degradation is one of the research highlights in the field of environmental remediation.In this paper,using naphthalene and phe-nanthrene as example,the microbial degradation mechanisms of PAHs are reviewed,and the application of“omics”technology in life science for research of microbial degradation of PAHs is summarized.The review lays a certain theoretical foundation for further exploring the microbial degradation and conversion mechanism for PAHs.
