Polycyclic aromatic hydrocarbons (PAHs) are toxic and persistent pollutants that widely distributed in the environment. PAHs to microorganisms pose ecological risks. Bacteria encode enzymes for PAH degradation through specific genes, thereby mitigating pollution. However, due PAHs' complexity, information on global potential, diversity, associated risks of PAH-degrading microbes soils is lacking. In this study, we analyzed 121 genes selected 33 as marker predict potential within soil microbiome. By constructing a Hidden Markov Model, identified 4990 species carrying 40,039 metagenomic assembly genomes, with Burkholderiaceae Stellaceae emerging high-potential degraders. We demonstrated candidate degraders predominantly emerged artificial farmland, significantly fewer present extreme environments, driven by factors such average annual rainfall, organic carbon, human modification terrestrial systems. Furthermore, comprehensively quantified each host future practical applications using three indicators (antibiotic resistance virulence factors, pathogenic bacteria). found degrader has significant application prospects. Our research will help determine biosynthetic globally further identify bacteria at lower risk.
