Researchers use efficient microbial electrosynthesis cells to convert CO2 to butyric acid; upgrade to butanol

Green Car Congress

The MES cell design proved highly efficient, with average cell voltages of 2.6–2.8 Resources Meritxell Romans-Casas, Laura Feliu-Paradeda, Michele Tedesco, Hubertus V.M. Solventogenic butanol production was triggered at a pH below 4.8 by interrupting CO 2 supply and maintaining specific pH and hydrogen partial pressure conditions.
