The effect of temperature on a very high gravity ethanol fermentation using no cook process was investigated. We found that a gradient temperature control strategy could improve the fermentation efficiency significantly, With the assistance of a new raw starch hydrolyzing enzyme and a gradient temperature control strategy, the ethanol concentration could reach up to 20% (V/V) within 90 h using commercially available dry yeast, when sorghum was used as the raw material and the dry substrate concentration was controlled at 35%.
研究了温度对采用免蒸煮工艺的超高浓度乙醇发酵的影响。我们发现梯度温度控制策略可显著提高发酵效率。在一种新型生淀粉水解酶和梯度温度控制策略的辅助下，以高粱为原料且干底物浓度控制在35%时，使用市售干酵母，乙醇浓度在90小时内可达到20%（V/V）。
