Enhanced Acetone-Butanol-Ethanol fermentation by continuous fermentation in the membrane cell-recycle bioreactor |
| 초록 |
Acetone-Butanol-Ethanol (ABE) fermentation is representative bio-based solvent production which is considered as alternative of petroleum-based chemicals. Among those solvents, butanol has great potential to be next generation fuel and the genus Clostridium naturally produces butanol by ABE fermentation utilizing various carbon sources. C. acetobutylicum BKM19 mutant strain and C. pasteurianum MBEL_GLY2 mutant strain showed hyper-ABE production by continuous fermentation with high cell density in the membrane cell-recycle bioreactor. The maximum ABE productivities of BKM19 strain and MBEL_GLY2 strain are 21.1 g/l/h and 8.3 g/l/h under the optimal condition, respectively.
