PROCESSES FOR PRODUCING FERMENTATION PRODUCTS

摘要

The present invention relates to processes for producing fermentation products from starch-containing material, wherein an alpha-amylase and optionally a thermostable protease, pullulanase and/or glucoamylase are present and/or added during liquefaction, wherein a cellulolytic composition is present and/or added during fermentation or simultaneous saccharification and fermentation. The invention also relates to a composition suitable for use in a process of the invention.

主权项

1. A process for producing fermentation products from starch-containing material comprising the steps of:
i) liquefying the starch-containing material at a temperature above the initial gelatinization temperature using:
an alpha-amylase;optionally a protease having a thermostability value of more than 20% determined as Relative Activity at 80° C./70° C.; andoptionally a carbohydrate-source generating enzyme; ii) saccharifying using a carbohydrate-source generating enzyme; iii) fermenting using a fermenting organism; wherein a cellulolytic composition is present or added during fermentation or simultaneous saccharification and fermentation.
