dc.description.abstractThis report describes an experiment conducted to see whether syngas fermentation could be integrated into the single-cell microbial electrosynthesis process. In some gasfermentation strategies, the primary bottleneck is restricted gas-liquid mass transfer. Consequently, we hypothesized that MES integration might break the thermodynamic barrier, resulting in more gas-liquid mass transfer and product formation rate. The research was carried out in two steps with feed-batch gas feeding. Surface electrodes were incorporated into the fermentation medium during the first step, and experiments were performed in open-circuit mode. The electrodes were positioned with a voltage in the second phase, and the second phase was extended in closed-circuit mode. The phase one, illustrated the average hydrogen consumption rate of 0.75 𝑚𝑚𝑜𝑙/𝐿 ∙ ℎ, which was the highest rate, and the average 0.18 𝑚𝑚𝑜𝑙/𝐿 ∙ ℎ acetic acid production rate. However, at the end of the second phase oxidation observed, the average acetic acid production rate was 0.15 𝑚𝑚𝑜𝑙/𝐿 ∙ ℎ. Before oxidation, the highest acetic acid production rate (0.62 𝑚𝑚𝑜𝑙/𝐿 ∙ ℎ) reported.
