摘要:
The invention relates to a process of producing a fermentation product, such as ethanol, from starch-containing material, including i) subjecting starch-containing material to an alpha-amylase, ii) subjecting the material obtained in step i) to an alpha-glucosidase and/or a maltose-generating enzyme, and iii) fermenting the material in the presence of a fermenting organism, such as yeast. Alternatively the invention relates to a process of producing a fermentation product from starch-containing material, preferably granular starch, which process comprises: a) subjecting starch-containing material to an alpha-glucosidase and optionally a glucose-generating and/or maltose-generating enzyme, and b) fermenting the material in the presence of a fermenting organism.
