Halogenated organic compounds including �old� agrochemicals are required to be degraded by Stockholm Convention on Persistent Organic Pollutants (POPs). Microbial degradation has been attracting attentions as one of the inexpensive methods for remediation. The microbial remediation technologies have been applied mainly for the excavated soil contaminated with oil (aerobic microbial degradation of aromatic compounds) and for the groundwater contaminated with chlorinated aliphatic solvents (anaerobic dechlorination). Halogenated aromatics (ones of POPs) often remain in the environments under anaerobic conditions. The combinations of anaerobic microbial dehalogenation and the aerobic microbial oxidation of aromatic rings have been proposed for the remediation of halogenated aromatics. However, changing the environment from anaerobic to aerobic is expensive and not realistic. The anaerobic microbial technologies are desired. We report here a combination method of the anaerobic microbial dehalogenation and anaerobic microbial oxidation for the remediation of halogenated aromatics under the anaerobic conditions.
