Removal of inhibitory nitrobenzene (NB) was investigated in single-chamber microbial fuel cells (MFCs) assembled with pre-enriched bioanodes and active carbon (AC) air-cathodes. High NB tolerance and NB removal were obtained in the present single-chamber MFCs with high electricity production. The maximum power over 25 W m-3 could be obtained when the present S-MFCs were operated in the NB loading range of 1.2 to 6.2 mol m-3 d-1, and stable electricity production over 13.7 W m-3 could be produced in a NB loading range of 1.2 to 14.7 mol m-3 d-1. The present single-chamber MFCs with AC air-cathodes exhibited high NB removal performance with NB removal efficiency over 97% even when the NB loading rate was increased to 17.2 mol m-3 d-1. The potential NB reduced product (i.e. aniline) could also be effectively removed from influents. The findings in this study means that single-chamber MFCs assembled with pre-enriched bioanodes and AC air-cathodes could be developed as effective bioelectrochemical systems to remove NB from wastewaters and to harvest energy instead of consuming energy
