Microbial electrocatalysis to guide biofuel and biochemical bioprocessing

摘要

During the last 10 years, research on bioelectrochemi-cal systems with alive microbes on anodes or cathodes (electrodes) has blossomed. We refer to microbial activity on electrodes as microbial electrocatalysis, especially when no artificial mediators are added to the cultures. Initially, researchers focused on converting organic materials in sediments or wastewater into spontaneous electric power production with microbial fuel cells. Researchers shaped an open culture of mixed microbial consortia to utilize the anode as a solid-state electron acceptor with, for example, a platinum-coated cathode for abiotic oxygen reduction.
