Syngas fermentation and microbial electrosynthesis integration as a single process unit.

Industrially relevant syngas (15 % CO, 15% H, 20% N in 50% CO) fermentation and microbial electrosynthesis were integrated as a single process unit in open and closed-circuit modes. This study examined the impact of electrochemical reducing power from -50 to -400 mV on the acetic acid synthesis and CO inhibition on fermentation. -150 mV vs.

Impact of electrochemical reducing power on homoacetogenesis.

Homoacetogenesis was performed in a microbial electrosynthesis single-chamber reactor at open and closed circuits modes. The aim is to investigate how an applied reducing power affects acetic acid synthesis and H gas-liquid mass transfer. At a cathode voltage of -175 mV vs.
