Reductive dechlorination and mineralization of pentachlorophenol in biocathode microbial fuel cells

► Biocathode MFC facilitated PCP mineralization through anaerobic and aerobic pathways. ► A temperature of 50 °C and a pH of 6.0 improved PCP degradation. ► A variety of aerobic and anaerobic microorganisms were found on the biocathode.
