Abstract: Benzo［a］pyrene (BaP) is one of the polycyclic aromatic hydrocarbons (PAHs) with carcinogenesis, aberrance and mutagenesis. To remedy BaPcontaminated soil, it is of significance to study the microbial metabolic pathway of BaP-degradation. In this paper, several factors affecting the process of BaP-biodegradation were introduced, including the degradation ability of different bacterium and fungus, metabolic pathway, substrates of co-metabolism, and environmental parameters. It was suggested that the accumulation and toxicity of BaP’s intermediate metabolites in contaminated soils would be an important aspect in the study of BaP-contaminated soil remediation.
