These can be used for the sustainable production of energy, bioremediation of metal-contaminated environments and production of added-value products. Currently, almost 100 microorganisms from the Bacterial and Archaeal domains are considered electroactive, given their ability to efficiently interact with electrodes in microbial electrochemical technologies. Cell-surface exposed conductive proteins are key players in the electron transfer between cells and electrodes. Interestingly, it seems that among the electroactive organisms identified so far, these cell-surface proteins fall into one of four groups. In this review, the different types of cell-surface conductive proteins found in electroactive organisms will be overviewed, focusing on their structural and functional properties.en0960-85242018308317Cell-surface exposed conductive proteinsElectroactive bacteriaExtracellular electron transferMicrobial electrochemical technologiesMultiheme c-type cytochromesJournal Article10.1016/j.biortech.2018.01.13329444758Other
