AB  - Polychlorinated biphenyls (PCBs) are the typical persistent organic pollutants 
      (POPs) in the environment. As a ubiquitous attenuation course of chlorinated 
      organic compounds in anoxic environment, the microorganism-mediated reductive 
      dechlorination process plays an important role in PCBs transformation, especially 
      the transformation of higher chlorinated PCBs. The higher chlorinated PCBs can be 
      dechlorinated in anaerobic condition, and thus, their persistence and toxicity 
      can be decreased. The resultant lower chlorinated PCBs from the dechlorination 
      can be further degraded and completely mineralized in aerobic condition. This 
      paper summarized the research advances of PCBs microbial reductive 
      dechlorination, introduced the mechanisms and characteristics of the 
      dechlorination and the related specific microorganisms, and approached the 
      affecting factors of PCBs bio-dechlorination, as well as the significances of 
      anaerobic dechlorination coupling with aerobic degradation. The future research 
      directions, including the complex metabolic networks of dechlorinating microbial 
      populations, the screening of novel specific dechlorinators and their practical 
      applications in the remediation of PCBs contaminated sites were also prospected.
