Abstract
Abstract
Benzo[a]pyrene, a high-molecular-weight polycyclic aromatic hydrocarbon, is a prevalent organic pollutant. In this study, a microbial community with high efficiency of BaP degradation was enriched in oil-contaminated soil, and the microbial community was immobilized using modified wheat straw biochar. The highest removal efficiency of 5–20 mg/L BaP was 75.18% in 12 days. Through 16SrRNA sequencing, Pseudomonas, Stenotrophomonas and Bacillus were found to be the dominant bacteria in the community. Additionally, metagenomic annotation revealed the gene function and metabolic pathway of the microbial community during BaP degradation.
