In this review, the sources and pollution conditions of SPAHs in soil were analyzed, and the different bacteria reported for SPAHs degradation and their degradation mechanism were reviewed. The Mycobacterium and Sphingobium are the main bacterium involved in NPAHs degradation. Some bacteria and fungi can degrade OPAHs, while the microorganisms for HPAHs degradation are mainly the bacteria. The effects and mechanisms of microbial remediation for SPAHs-contaminated soil were also reviewed. In the biodegradation processes, SPAHs are first transformed to intermediates, which are further degraded to phthalic acid or/and salicylic acid under enzymatic hydrolysis, and finally mineralized through the tricarboxylic acid cycle. It is suggested that the degradation of SPAHs based on synergistic flora and immobilized microbial agents and the microbial remediation for SPAHs-contaminated soil are the important research direction worthy of attention in the future.
