水体沉积物中微生物厌氧呼吸耦合多环芳烃降解的研究进展
|
摘要
多环芳烃(Polycyclic aromatic hydrocarbons,PAHs)是一种具有致癌、致畸、致突变的持久性有机污染物。本文在分析国内外主要水体沉积物中PAHs污染状况的基础上,综述了近几年有关厌氧水体沉积物中微生物以硝酸盐、Fe(III)以及硫酸盐为电子受体进行呼吸耦合PAHs降解的研究概况。此外,还总结了基于微生物的PAHs降解基因组、蛋白质组、代谢组以及菌群水平上互作网络的研究进展,以期为进一步加速PAHs污染水体沉积物原位生物修复提供科学理论参考。
Polycyclic aromatic hydrocarbons are a group of refractory organic compounds well known for their carcinogenesis, teratogenesis and mutagenesis. This review summarizes recent degradative patterns based on investigations on worldwide polycyclic aromatic hydrocarbons contamination in aquatic sediments, in which microbial respiration couples polycyclic aromatic hydrocarbons degradation by using nitrate, Fe(III) and sulfate as electron acceptors. In addition, polycyclic aromatic hydrocarbons degradation-related genome, proteome, and metabolomics of microbial organism as well as community interactive networks, are also involved so as to further complement the theory of in-situ bioremediation of polycyclic aromatic hydrocarbons contaminated sediments.
