Abstract: The present invention provides a process of fermenting starch-containing material, comprising i) fermenting starch-containing material by subjecting said material to a carbohy-drate-source generating enzyme and a fermenting microorganism, ii) reducing the particle size of the starch-containing material obtained from step i) and/or liquefying the starch-containing material obtained from step i), and iii) fermenting the liquefied material from step ii). The invention also relates to a process of producing a fermentation product including the fermentation process of the invention.

Abstract: The present invention provides a process of producing a fermentation product including introducing the fermenting organism into the fermentation medium and thereafter adding a carbohydrate generating enzyme after the lag phase of the fermenting organism and then carry out fermentation under conditions suitable for producing the fermentation product in question. The invention also relates to fermentation product producing processes including the fermentation process of the invention.
