Selective butyric acid production from CO and its upgrade to butanol in microbial electrosynthesis cells.

Microbial electrosynthesis (MES) is a promising carbon utilization technology, but the low-value products (i.e., acetate or methane) and the high electric power demand hinder its industrial adoption.

Thermodynamic approach to foresee experimental CO reduction to organic compounds.

Anaerobic gas fermentation is a promising approach to transform carbon dioxide (CO) into chemical building blocks. However, the main operational conditions to enhance the process and its selectivity are still unknown. The main objective of this study was to trigger chain elongation from a joint perspective of thermodynamic and experimental assessment.
