Unveiling degradation mechanism of PAHs by a Sphingobium strain from a microbial consortium.

ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs) are a class of persistent pollutants with adverse biological effects and pose a serious threat to ecological environments and human health. The previously isolated phenanthrene-degrading bacterial consortium (PDMC) consists of the genera Sphingobium and Pseudomonas and can degrade a wide range of PAHs. To identify the degradation mechanism of PAHs in the consortium PDMC, metagenomic binning was conducted and a Sphingomonadales assembly genome with 100% completeness was obtained. Additionally, Sphingobium sp. SHPJ-2, an efficient degrader of PAHs, was successfully isolated from the consortium PDMC. Strain SHPJ-2 has powerful degrading abilities and various degradation pathways of high-molecular-weight PAHs, including fluora
