The effects of different environmental factors on the biodegradability of bacteria were studied by single factor experiment. The intermediate metabolites degraded by benzo[a]pyrene were analyzed by gas chromatography-mass spectrometry (GC-MS). The results of macrogene sequencing showed that the dominant genera of this bacterium were Pseudomonas and Methyloversatilis. After 14 days of culture, the degradation rate of 30 mg/L BaP was stable at 38.69%±6.24%, and the degradation effect of phenanthrene and pyrene was better. YQ-BaP showed strong degradation ability at pH=7 and 35~40℃. When the concentration of BaP was 20 mg/L, the degradation rate of BaP reached 46.89%. GC-MS analysis showed that phenanthrene, anthracene, naphthalene and other hydroxylation and methylation metabolites were produced during BaP degradation. The bacterial community has a strong ability to degrade BaP, which provides a theoretical basis for the remediation technology of PAHs pollution., authors=YI Qianwen¹, XIAO Fang¹, ZOU Xiaoshuang¹, LI Jiang^1,2, ZHANG Yuntao¹, DAI Yongheng¹, WANG Bin³, HOU Li'an⁴, authorsList=YI Qianwen, XIAO Fang, ZOU Xiaoshuang, LI Jiang, ZHANG Yuntao, DAI Yongheng, WANG Bin, HOU Li'an, authorCompany=1.
