dc.description.abstract | In cellulosic ethanol production, use of simultaneous saccharification and fermentation (SSF) has been suggested as the favorable strategy to reduce process costs. Although SSF has many advantages, a significant discrepancy still exists between the appropriate temperature for saccharification (45-50 A degrees C) and fermentation (30-35 A degrees C). In the present study, the potential of temperature-shift as a tool for SSF optimization for bioethanol production from cellulosic biomass was examined. Cellulosic ethanol production of the temperature-shift SSF (TS-SSF) from 16 w/v% biomass increased from 22.2 g/L to 34.3 g/L following a temperature shift from 45 to 35 A degrees C compared with the constant temperature of 45 A degrees C. The glucose conversion yield and ethanol production yield in the TS-SSF were 89.3% and 90.6%, respectively. At higher biomass loading (18 w/v%), ethanol production increased to 40.2 g/L with temperature-shift time within 24 h. These results demonstrated that the temperature-shift process enhances the saccharification ratio and the ethanol production yield in SSF, and the temperature-shift time for TS-SSF process can be changed according to the fermentation condition within 24 h. | - |
