This study investigates sub-stoichiometric electron supply, also termed electro-fermentation, to influence product formation in gas fermentation. Two species, Clostridium carboxidivorans and Alkalibaculum bacchi, as well a co-culture of A. bacchi kluyveri, were tested batch cultures with without an external cell potential 800 mV. The supplied mixture was 50:40:10 N2:H2:CO2. test unit single-chamber reactor cathode made from electrically conducting composite PP black carbon. observed current densities generally very low, around 0.22 mA/m2. Despite that, significant reproducible change patterns rates occurred. C. increased the acetate (+32%), butyrate (+300% relative control), caproate (+600% control). In similar manner, produced more (+38%), (13 times than (only electrified setup). Additional trials using modified phase composition, 80:20 H2:CO2, confirmed finding that application electric enhances chain elongation alcohol formation. Moreover, experiment reversed polarity showed high surface area is essential for inducing metabolic modifications. results demonstrate electro-fermentation holds improving bioconversion processes aimed at producing green chemicals.
