摘　　要：Bioelectrochemical systems(BESs)are a new and emerging technology in the field of fermentation technology.Electrical energy was provided externally to the microbial electrolysis cells(MECs)to generate hydrogen or value-added chemicals,including caustic,formic acid,acetic acid,and peroxide.Also,BES was designed to recover nutrients,metals or remove recalcitrant compounds.The variety of naturally existing microorganisms and enzymes act as a biocatalyst to induce poten-tial differences amid the electrodes.BESs can be performed with non-catalyzed electrodes(both anode and cathode)under favorable circumstances,unlike conventional fuel cells.In recent years,value-added chemical producing microbial electrosyn-thesis(MES)technology has intensely broadened the prospect for BES.An additional strategy includes the introduction of innovative technologies that help with the manufacturing of alternative materials for electrode preparation,ion-exchange membranes,and pioneering designs.Because of this,BES is emerging as a promising technology.This article deliberates recent signs of progress in BESs so far,focusing on their diverse applications beyond electricity generation and resulting performance.
