From: Extracellular electron transfer from cathode to microbes: application for biofuel production

Fig. 5

The upgrade of waste into value-added biofuels. The acetate from wastes, such as waste activated sludge, food waste, and animal manure, was feed stocks for biofuel production by electroactive microorganisms. The extracellular electron transfer from cathode to microbe via electron transfer protein could be used for the reduction of acetate to butanol. NADH the reduced form, NAD+ the oxidized form of nicotinamide adenine dinucleotide, respectively
