摘要： The invention relates to an improved process of producing a fermentation product, such as ethanol, from starch-containing material using an increased dosage of alpha-amylase during liquefaction, which results in increased conversion of dextrins compared to conventional processes, and/or a reduced dosage of carbohydrate-generating enzyme during simultaneous saccharification and fermentation compared to a conventional process carried out at the same conditions. A process of the invention results in an increased yield. The invention also relates to an improved process of producing a fermentation product resulting in substantially the same yield as a conventional process, wherein reduced dosage of carbohydrate-source generating enzyme is used during simultaneous saccharification and fermentation.

摘要翻译： 本发明涉及使用在液化期间使用增加的α-淀粉酶剂量的含淀粉材料来生产发酵产物如乙醇的改进方法，其与常规方法相比导致糊精的转化率增加，和/或减少 与在相同条件下进行的常规方法相比，在同时糖化和发酵期间产生碳水化合物的酶的剂量。 本发明的方法导致产量增加。 本发明还涉及生产发酵产物的改进方法，其产生与常规方法基本相同的产量，其中在同时糖化和发酵期间使用碳水化合物源产生酶的减少的剂量。
