Patent ID: 8883456

Claim:
A process of producing a fermentation product, comprising converting a starch-containing material to a dextrin with an alpha-amylase; saccharifying the dextrin to a sugar with a saccharifying enzyme; and fermenting the sugar using a fermenting organism in the presence of a glycoside hydrolase Family 61 polypeptide in a single step at a temperature below the initial gelatinization temperature of the starch-containing material, wherein the glycoside hydrolase Family 61 polypeptide is present in an amount which results in a greater amount of the fermentation product than the amount of the fermentation produced by the same process without the glycoside hydrolase Family 61 polypeptide, and wherein the glycoside hydrolase Family 61 polypeptide has at least 90% sequence identity of SEQ ID NO: 25.
