In gas fermentation, a range of chemolithoautotrophs fix single-carbon (C1) gases (CO 2
and CO) when H 2 or other reductants are available. Microbial electrosynthesis (MES) …

Industrial biotechnology has a potential to tackle harmful CO 2 emissions and turn CO 2 into
a valuable commodity. However, a major technical obstacle in gas fermentations is the …
