“…This accomplishment was made possible through metabolic engineering, involving the introduction of a heterologous enzyme, farnesene synthase, from a plant species (Citrus junos), into the MEP pathway. [37] Theses findings suggest that the distinct performance of mCO2ER with a wet amine-based catholyte medium offers practical applications, considering economic feasibility by coupling the valorization of the target production from CO 2 .…”

Microbial CO2 electroreduction (mCO2ER) offers a promising approach for producing high‐value multicarbon reductants from CO2 by combining CO2 fixing microorganisms with conducting materials (i.e., cathodes). However, the solubility and availability of CO2 in an aqueous electrolyte pose significant limitations in this system. This study demonstrates the efficient production of long‐chain multicarbon reductants, specifically carotenoids (~C40), within a wet amine‐based catholyte medium during mCO2ER. Optimizing the concentration of the biocompatible CO2 absorbent, monoethanolamine (MEA), led to enhanced CO2 fixation in the electroautotroph bacteria. Molecular biological analyses revealed that MEA in the catholyte medium redirected the carbon flux towards carotenoid biosynthesis during mCO2ER. The faradaic efficiency of mCO2ER with MEA for carotenoid production was 4.5‐fold higher than that of the control condition. These results suggest the mass transport bottleneck in bioelectrochemical systems could be effectively addressed by MEA‐assissted mCO2ER, enabling highly efficient production of valuable products from CO2.
