Bioelectrochemical systems offer unique opportunities to remove recalcitrant environmental pollutants in a net positive energy process, although it remains challenging because of the toxic character such compounds. In this study, microbial fuel cell (MFC) technology was applied investigate benzene degradation process for more than 160 days, where glucose used as co-metabolite and control. We have an inoculation strategy that led development 10 individual communities. The electrochemical dynamics MFC efficiency observed, along with their
