Functional interplays of microbial activity, genetic diversity and contaminant transformation are poorly understood in reactors for mineralizing halogenated aromatics anaerobically. Here, we investigated abundance and distribution of potential microbes and functional genes associated with pentachlorophenol (PCP) anaerobic mineralization in a continuous-flow cylindrical reactor (15 cm in length). PCP dechlorination and the metabolite (phenol) were observed at segments 0–8 cm from inlet, where key microbes, including potential reductive dechlorinators ( Dehalobacter ,  Sulfurospirillum ,  Desulfitobacterium  and  Desulfovibrio  spp.) and phenol degraders ( Cryptanaerobacter  and  Syntrophus  spp.), as well as putative functional genes, including putative chlorophenol reductive dehalogenase ( cprA ) and benzoyl-CoA reductase ( bamB ), were highly enriched simultaneously. Five types of putative  cprA s, three types of putative  bamB s and seven types of putative nitrogenase reductase ( nifHs ) were determined, with their copy numbers decreased gradually from inlet to outlet. Distribution of chemicals, bacteria and putative genes confirmed PCP dechlorination and phenol degradation accomplished in segments 0–5 cm and 0–8 cm, respectively, contributing to a high PCP mineralization rate of 3.86 μM d −1 . Through long-term incubation, dechlorination, phenol degradation and nitrogen fixation bacteria coexisted and functioned simultaneously near inlet (0–8 cm), verified the feasibility of anaerobic mineralization of halogenated aromatics in the compact reactor containing multiple functional microbes.
