Selective Enrichment Establishes a Stable Performing Community for Microbial Electrosynthesis of Acetate from CO₂.

The advent of renewable energy conversion systems exacerbates the existing issue of intermittent excess power. Microbial electrosynthesis can use this power to capture CO2 and produce multicarbon compounds as a form of energy storage. As catalysts, microbial populations can be used, provided side reactions such as methanogenesis are avoided.
