Abstract
The invention is directed to methods of producing ethanol and decreasing residual starch production in a no cook fermentation comprising contacting granular starch containing substrates with a granular starch hydrolyzing enzyme, a protease, and a fermenting microorganism under suitable fermentation conditions at a temperature below the starch gelatinization temperature of the starch substrate to produce ethanol, wherein the ethanol production is increased and the amount of residual starch is decreased compared to a substantially similar method conducted without the protease.
