Electrobiocommodities: powering microbial production of fuels and commodity chemicals from carbon dioxide with electricity

► Microbes can efficiently reduce CO2 to organic commodities with electrical energy. ► Direct electrode-to-microbe electron transfer can support anaerobic CO2 respiration. ► Electrochemically generated H2 can support anaerobic or aerobic CO2 reduction. ► Anaerobic CO2 respiration yields high recovery of electrons in organic commodities. ► If scalable, electrobiocommodities could revolutionize biocommodity production.
