Abstract

Electricity can be an energy source for microbially catalyzed production of fuels and other organic commodities from carbon dioxide. These electrobiocommodities (E-BCs) can be produced directly via electrode-to-microbe electron transfer or indirectly with electrochemically generated electron donors such as H2 or formate. Producing E-BCs may be a more efficient and environmentally sustainable strategy for converting solar energy to biocommodities than approaches that rely on biological photosynthesis. A diversity of microbial physiologies could potentially be adapted for E-BC production, but to date acetogenic microorganisms are the only organisms shown to covert electrically generated low potential electrons and carbon dioxide into multi-carbon organic products with high recovery of electrons in product. Substantial research and development will be required for E-BC commercialization.
