Microbial electrochemical technologies (MET) is an interdisciplinary approach where microbes are used as bio-catalyst for the treatment of wastewater and generation of value-added products like electricity, biofuels etc. This technology is very robust and thus can also be used for the removal of bio-refractory substances from industrial wastewater. This short review presents gist of research demonstrating the use of this technology for the removal of recalcitrant pollutants from wastewater.
