Halophilic CO-fixing microbial community as biocatalyst improves the energy efficiency of the microbial electrosynthesis process.

Using saline electrolytes in combination with halophilic CO-fixing lithotrophic microbial catalysts has been envisioned as a promising strategy to develop an energy-efficient microbial electrosynthesis (MES) process for CO utilization. Here, an enriched marine CO-fixing lithotrophic microbial community dominated by Vibrio and Clostridium spp. was tested for MES of organic acids from CO.
