| Abstract Scope |
Electromicrobiology is an emerging field of study that investigates microbial electron exchange with external electrodes and microbial electrochemical functionalities. Significant advances in electromicrobiology have occurred, led by impressive discoveries of “Exoelectrogens,” which are microorganisms capable of direct electron transfer to electrodes. By incorporating exoelectrogens into a bioelectrochemical cell, the combined biotic-abiotic system offers a solution for environmental sustainability by generating renewable bioelectricity with organic waste while producing value-added chemicals/biofuels. Despite its vast potential, however, the technology’s promise has not yet been translated as application (or market demand) because of its low power generation. Bacterial metallic nanoparticles synthesized from bacterial metabolism are garnering considerable attention because of their high potential for facilitating microbial extracellular electron transfer. In this study, exoelectrogens will be demonstrated to be capable of synthesizing conductive nanoparticles which improve the electron transfer efficiency and thus significantly increase the power performance in the bioelectrochemical cell. |
