By completely removing starch from grain samples using special enzymes, NREL’s method sidesteps inaccuracies present in current analytical methods.
Federal incentives can help ethanol refiners expand their plants into generation 1.5 biorefineries designed to make ethanol from both the cellulose and starch sugars found in corn grain. To apply for such support, however, biorefiners need a robust but simple analytical process for measuring the amount of cellulose in their grain.
