Abstract:In order to improve microbial electromethane generation (mEMG) with CO 2 conversion using excess renewable power, an electrical stimulation period was optimized to enrich active microorganisms on a biocathode and directionally strengthened electron transfer with a start-up mode of stepwisepromoted intermittent voltage. A highly adaptive microbial community was enriched on the biocathode for an electrical stimulation period of 1 h with the highest population abundance and diversity of archaea and bacteria.
