| 摘 要： | 主要阐述了微生物降解PAHs的机理,比较了典型微生物种类芽孢杆菌(Bacillus)和分支杆菌(M.vanbaalenii PYR-1)对同种PAHs菲的代谢过程不同之处,并分析了分支杆菌(M.vanbaalenii PYR-1)对菲和芘的代谢机理,指出微生物氧化降解PAHs主要从其K区和湾区开始,而K区氧化是有毒PAHs降解的主要可能途径,资料显示真菌比细菌对苯并a]芘的降解能力更强,同时给出了微生物代谢菲、芘和苯并a]芘的降解图,以便做进一步研究。

| Abstract: | This paper introduced the mechanism of microbial degradation PAHs in the soil, compared the different degradation metabolic processes for phenanthrene by Bacillus sp. and Mycobacterium sp., analyzed the metabolic processes for phenanthrene and pyrene by M.vanbaalenii PYR-1, stated that the degradation for PAHs by microbial oxidation mainly begin from K- and Bay- region, and the degradation of the toxic PAHs is mainly attributed to the oxidation of K- region. Fungi have stronger degradation ability to the benzoa]pyrene comparing to bacteria. Also this paper gave the proposed pathways for phenanthrene, pyrene and benzoa]pyrene for the further research. |
