Abstract: Polycyclic aromatic hydrocarbons(PAHs), a class of crucially persistent pollutants with two or more fused benzene rings, have attracted growing concern due to their carcinogenic, teratogenic and mutagenic effects. The biodegradation progress of typical PAHs with different molecular masses by microorganisms including bacteria, fungi and algae isolated from contaminated soil or sediments is reviewed. The biotransformation mechanisms, key enzymes and metabolic pathways of four representative pollutants of naphthalene, anthracene, phenanthrene and benzo[a]pyrene were discussed. Still, the crucial impacting factors, such as bioavailability of PAHs, microbial activity and environmental factors, to increase biodegradation rate are introduced. Finally, it is advanced that studies on a high-effective microbial consortium and synergetic degradation will be considered as the important means aiming at the diversity of PAHs in the environment, which can effectively avoid the contingency and randomness in the development of PAH-degrading microbes as main direction, and is niche targeting and effective to improve the utilization of available resources.
