硫酸盐还原菌对多环芳烃降解的研究进展综述

Overview of Research Advances in Degradation of Polycyclic Aromatic Hydrocarbons by Sulfate-Reducing Bacteria

多环芳烃(PAHs)是环境中广泛分布的一类有机物。其广泛分布于水、大气土壤中,且有相当毒害。近年来关于多环芳烃厌氧降解的研究已经逐渐成为人们研究的重点,虽然国内外已有研究关于多环芳烃的厌氧降解体系,但对于硫酸盐还原菌(SRB)降解PAHs的深层研究仍需不断发展和优化。比较了多环芳烃厌氧降解的各种体系,介绍了硫酸盐还原菌降解多环芳烃的机理,总结了硫酸盐还原体系的影响因素。

Polycyclic aromatic hydrocarbons （ PAHs） is a type of organic compounds widely existing in the environment. It is distributed in water, air and soil widely, which has quite toxicity. In recent years, anaerobic degradation of PAHs gradually become research emphases, and the research in degradation of PAHs by sulfate-reducing bacteria （SRB） is continuously developing and optimizing process. By comparing various anaerobic degradation systems of PAHs, the mechanism of sulfate-reducing bacteria degradation of PAHs was introduced, factors of sulfate reduction system were also summarized.
