Autotrophic microbial electrosynthesis (MES) processes are mainly based on organisms that rely carbon dioxide (CO2) as an electron acceptor and typically have low biomass yields. However, there few data the process efficiencies of oxic MES (OMES). In this study, we used knallgas bacterium Kyrpidia spormannii to investigate formation energy efficiency cathode-dependent growth. The study revealed can be carried out with same conventional gas fermentation, but overcomes disadvantages, such use explosive mixtures. When accounting only for input via electrical energy, a solar demand 67.89 kWh kg-1 dry was determined. While anaerobic is ideally suited produce methane, short-chain alcohols, carboxylic acids, its aerobic counterpart could extend important range applications not protein in food feed sector, also further complex products.
