| 英文摘要 | A solid state fermentation (SSF) of sweet sorghum stalk to ethanol was conducted in 250-mL flask using thermotolerant Issatchenkia orientalis IPE 100, and the optimal operation parameters were determined as 42 C fermentation temperature, 75% (w/w) water content, 2 mm particle size and 3% (w/w) inoculation rate in 250-mL conical flask. When the SSF was scaled up from the flask to a 10-L bioreactor, temperature gradient in the substrate bed was observed due to heat accumulation in the bioreactor. The temperature gradient was dependent on both substrate depth and operation temperature. Due to high thermotolerance of the strain IPE 100, a deep-bed SSF of sweet sorghum stalk was developed in the bioreactor. The highest ethanol yield of 0.25 g-ethanol/g-dry stalk was obtained at 37 degrees C with 15-20 cm substrate depth in the bioreactor. These results provided a great potential for large-scale deep-bed SSF in practice. (C) 2011 Elsevier Ltd. All rights reserved. |
