微生物降解是治理多环芳烃污染的有效技术之一。一些细菌，真菌和蓝藻菌株已被分离和用于生物修复的目的。本文旨在提供关键信息的各种步骤和演员参与的细菌和真菌的有氧和厌氧降解芘，高分子量的多环芳烃，包括分解代谢基因和酶，以扩大我们对芘降解的理解。综述了范氏分枝杆菌（Mycobacterium vanbaalenii PRY-1）和分枝杆菌属（Mycobacterium sp. KMS）的好氧降解途径以及兼性细菌厌氧假单胞菌（Pseudomonas sp. JP1）和克雷伯氏菌（Klebsiella sp. LZ6）的厌氧降解途径，以描述芘完整的降解机理途径。列举了具有降解芘能力的不同微生物菌株，并对聚合体降解芘进行了讨论。未来关于芘厌氧降解的研究将是了解和解决降解机制途径的一个伟大举措，因为尽管一些菌株被鉴定出在缺氧或完全缺氧的情况下降解芘，但超过90%的降解途径仍然不清楚和不完整。此外，本审查建议使用的各种菌株的厌氧真菌和真菌财团和厌氧细菌的组合，以实现最大效率的芘生物降解机制。
Microbial biodegradation is one of the acceptable technologies to remediate and control the pollution by polycyclic aromatic hydrocarbon (PAH). Several bacteria, fungi, and cyanobacteria strains have been isolated and used for bioremediation purpose. This review paper is intended to provide key information on the various steps and actors involved in the bacterial and fungal aerobic and anaerobic degradation of pyrene, a high molecular weight PAH, including catabolic genes and enzymes, in order to expand our understanding on pyrene degradation. The aerobic degradation pathway by Mycobacterium vanbaalenii PRY-1 and Mycobactetrium sp. KMS and the anaerobic one, by the facultative bacteria anaerobe Pseudomonas sp. JP1 and Klebsiella sp. LZ6 are reviewed and presented, to describe the complete and integrated degradation mechanism pathway of pyrene. The different microbial strains with the ability to degrade pyrene are listed, and the degradation of pyrene by consortium is also discussed. The future studies on the anaerobic degradation of pyrene would be a great initiative to understand and address the degradation mechanism pathway, since, although some strains are identified to degrade pyrene in reduced or total absence of oxygen, the degradation pathway of more than 90% remains unclear and incomplete. Additionally, the present review recommends the use of the combination of various strains of anaerobic fungi and a fungi consortium and anaerobic bacteria to achieve maximum efficiency of the pyrene biodegradation mechanism.
