Biochemical production with microbial bioelectrochemical systems

Current Opinion in Biotechnology
Microbial bioelectrochemical systems (BES) represent a promising platform for sustainable biochemical production by leveraging microbial electrocatalysis. These systems utilize electrical energy to drive microbial metabolic processes, enabling the recovery of CO₂ into valuable organic molecules such as methane, acetate, ethanol, and other biochemicals.
