Isolation of electroactive CO converting microorganism using zero valent iron for bioelectrochemical system (BES) |
| 초록 |
Carbon monoxide (CO) is one of the main gas component of steel industry and biomass gasification process. CO has also been highlighted as a feedstock for biological conversion to platform and value-added chemicals. The conventional CO converting strains have drawbacks of slow growth rate and high sensitivity to oxygen as well as low conversion yield. Most CO conversion microbe harbor wood-ljungdahl pathway (WL pathway) and CO-dehydrogenase, and the reducing equivalent is significantly limited for acetyl-CoA synthesis. In this study, we attempted to isolate and characterize an electrochemically active CO converting strains using the iron granules (Fe0) as external electron donor. We hypothesize that the CO uptake with iron oxidizing is be able to enhance biolectrochemical activity in electrosynthesis of CO. As a result, 9 strains were isolated. We examined the VFA production in a bioelectrochemical system (BES) using CO as substrate, and identified their electrochemical performance. |
