Ethanol Production

Applications Thermostable alpha-amylase (CAS 9000-90-2) is applied during high-temperature liquefaction of corn, wheat, or cassava mash (85–105°C) to reduce viscosity and hydrolyze gelatinized starch into dextrins, enabling efficient downstream saccharification and improved pumpability. Acid protease (CAS 9014-01-1) is dosed in mash or fermentation to hydrolyze grain proteins under acidic conditions, increasing free amino nitrogen (FAN) and supporting yeast performance and ethanol yield. Cellulase (CAS 9012-54-8) is used in lignocellulosic bioethanol processes to break down cellulose into fermentable sugars after pretreatment, improving conversion rates and overall sugar recovery. Specialized protease-based molasses formulations enhance nutrient availability and fermentation stability in cane and beet molasses ethanol plants. Product Range The portfolio covers thermostable alpha-amylase, acid protease, and cellulase preparations supplied in liquid form with industrial activity grades suitable for large-scale ethanol and biofuel operations. Food-grade and technical-grade options are available depending on plant requirements, with activity ranges tailored for high-solids mashes and continuous processing. Products are manufactured for consistent batch-to-batch performance and are suitable for scale-up from pilot trials to full commercial production.
