摘要
Although many anaerobic microorganisms that can degrade PAHs have been harnessed, there is still a large gap between laboratory achievements and practical applications. Here, we review the recent advances in the biodegradation of PAHs under anoxic conditions and highlight the mechanistic insights into the metabolic pathways and functional genes. Achievements of practical application and enhancing strategies of anaerobic PAHs bioremediation in soil were summarized. Based on the concerned issues during research, perspectives of further development were proposed including time-consuming enrichment, byproducts with unknown toxicity, and activity inhibition with low temperatures. In addition, meta-omics, synthetic biology and engineering microbiome of developing microbial inoculum for anaerobic bioremediation applications are discussed. We anticipate that integrating the theoretical research on PAHs anaerobic biodegradation and its successful application will advance the development of anaerobic bioremediation.
