Abstract
The invention relates to a process of fermenting plant material in a fermentation medium into a fermentation product using a fermenting organism, wherein one or more deamidases are present in the fermentation medium.
Claims15
A process of producing a fermentation product, comprising:
- (a) converting a starch-containing material to dextrins with an alpha-amylase;
- (b) saccharifying the dextrins to a sugar with a glucoamylase;
- (c) adding a deamidase;
- and
- (d) fermenting the sugar using a fermenting organism.
(canceled)
A modified fermenting organism transformed with a polynucleotide encoding a deamidase, wherein the fermenting organism is capable of expressing the deamidase at fermentation conditions.
A composition comprising a deamidase, a glucoamylase and an alpha-amylase.
