    摘要： The present invention relates to a process for liquefying starch-containing material, comprising treating the starch-containing material with a bacterial alpha-amylase at a temperature between 70-90° C. for 10-120 minutes and a pullulanase at a temperature in the range from 40-60° C. for between 20 and 90 minutes. The invention also relates to a saccharification process for saccharifying liquefied starch-containing material, comprising saccharifying a liquefied starch-containing material in the presence of a carbohydrate-source generating enzyme and a pullulanase. Finally, the invention also relates to a process of producing a fermentation product, such as ethanol, comprising a liquefaction step and/or saccharification step carried out in accordance with the present invention.

    摘要翻译： 本发明涉及一种用于液化含淀粉材料的方法，包括在70-90℃的温度下用细菌α-淀粉酶处理含淀粉的物质10-120分钟，并在该温度下处理支链淀粉酶 范围为40-60°C，时间为20至90分钟。 本发明还涉及用于糖化含液化淀粉材料的糖化方法，包括在碳水化合物源产生酶和支链淀粉酶存在下糖化含液化淀粉的材料。 最后，本发明还涉及生产发酵产物如乙醇的方法，其包括根据本发明进行的液化步骤和/或糖化步骤。
