Abstract: Energy crisis and water pollution are issues of considerable concerns today. This study focused on microbial fuel cell (MFC) technologies for pollutant removal, pharmaceutical compound (paracetamol) degradation, resource (metal and bioelectricity) recovery, carbon dioxide mitigation, valuable chemical (formate) production and toxicity sensing toward heavy metal (copper) in aqueous solutions. By using the bioelectrons captured from wastewater, an MFC-Fenton system was proved to be efficient in non-biocompatible pharmaceutical degradation, an MFC-powered enzymatic fuel cell was found to be applicable to formate synthesis from CO2 reduction, and MFC-sensor was demonstrated as a promising candidate for monitoring copper concentration and its potential toxicity in real domestic wastewater. The electrochemically active bacteria, which drive the release of bioelectrons for those above bioelectrochemical processes, were identified and analyzed based on mass spectrometry. The wide application of MFC in contaminant elimination and resource recovery makes this technology a competitive tool in environmental and energy engineering.
