Research Progress on Microbial Degradation Mechanisms for Polycyclic Aromatic Hydrocarbons

Wang Ta

Abstract

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 phenanthrene as example,the microbial degradation mechanisms of PAHs are reviewed,and the application ofomicstechnology 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.
