Through the business deal, the company intends to make use of the enzymes for grain-based ethanol plants.
Illinois/USA – Archer Daniels Midland Company (ADM) and Du Pont Industrial Biosciences have recently announced a collaboration to develop, produce and market cellulase enzymes for operators of grain-based ethanol plants.
Cellulase enzymes assist in hydrolyzing the corn kernel fiber, which consists mostly of cellulose and hemicellulose carbohydrates. Once the fiber is broken down, more sugars can be liberated and then fermented into ethanol, helping grain-based fuel ethanol producers get more out of existing feedstocks. As corn kernel fiber is part of a lower-value co-product stream, the potential to develop more valuable ‘Gen 1.5’ ethanol is attractive.
Ethanol from corn kernel fiber may qualify for D3 RINS under the Renewable Fuel Standard, which encourages producers to use technology in order to utilize non-starch components of grains and other waste products in the production of biofuels.
Initial product prototypes have proven successful in both laboratory and ethanol plant scale testing, and more evaluations are planned.
