Under anaerobic conditions, certain bacteria can produce electricity. This behavior can be exploited in microbial fuel cells, with a special focus on wastewater treatment schemes. A weak point is the dissatisfactory power density of the microbial cells. An unconventional solution: scientists coated live, electroactive bacteria with a conducting polymer and obtained a high-performance anode for microbial fuel cells.
