Abstract: The present invention relates to processes of producing a fermentation product from starch containing material comprising (a) forming a slurry comprising the starch-containing material and water; (b) converting the starch-containing material into dextrins with an alpha-amylase; (c) saccharifying the dextrins using a carbohydrate source generating enzyme to form sugars; (d) fermenting sugars using a fermenting organism; (e) recovering the fermentation product to form whole stillage; (f) separating the whole stillage into a liquid fraction thin stillage and solid fraction wet cake; (g) hydrolyzing the thin stillage; (h) recycle a portion of the hydrolyzed thin stillage to steps (a); wherein the thin stillage in step (g) is hydrolyzed using a glucoamylase and/or polygalacturonase.

Abstract: A process of recovering oil, comprising (a) converting a starch-containing material into dextrins with an alpha-amylase; (b) saccharifying the dextrins using a carbohydrate source generating enzyme to form a sugar; (c) fermenting the sugar in a fermentation medium into a fermentation product using a fermenting organism; (d) recovering the fermentation product to form a whole stillage; (e) separating the whole stillage into thin stillage and wet cake; (e′) optionally concentrating the thin stillage into syrup; (f) recovering oil from the thin stillage and/or optionally the syrup, wherein a protease and a phospholipase are present and/or added during steps (a) to (c). Use of a protease and a phospholipase for increasing oil recovery yields from thin stillage and/or syrup in a fermentation product production process.
