Conductive magnetite nanoparticles enhance the microbial electrosynthesis of acetate from CO2 while diverting electrons away from methanogenesis
Microbial electrosynthesis (MES) is an emerging technology which exploits microbial cells to convert CO2 into fuels, and value-added chemicals using electrons supplied by a solid-state cathode. Methane and acetic acid are typically the main CO2-reduction products attained in microbial electrosynthesis studies, although the production of other more valuable products has also been reported.
