| Outline of Final Research Achievements |
The fermentation conditions including pH and overall oxygen transfer coefficient (kLa) were optimized to improve 1,3-butanediol production by metabolically engineered Escherichia coli. AdhP, EutG, and YqhD in E. coli were identified as alcohol dehydrogenases that catalyze the reduction of 3-hydroxybutyraldehyde to 1,3-butanediol. A CoA-dependent butanol synthetic pathway that functions under aerobic conditions was constructed in E. coli, by expanding the previously reported 1,3-butanediol synthetic pathway.
