A new "robust" starch liquefaction enzyme for biofuels application was launched at the 2010 Fuel Ethanol Workshop and Expo (FEW) in St. Louis, Missouri (United States). The enzyme called Spezyme RSL^TM is produced by the biotechnology company, Genencor. The formulation is said to efficiently liquefy starch in dry ground corn or milo, and significantly reduces production cost for ethanol production. Starch is the main component in corn which must be broken down (or "liquefied") into simple sugars for "corn-ethanol" production. According to the company, the enzyme "breaks down starch efficiently across a range pH levels, substantially reducing the amount of sulfuric acid that is required to complete the liquefaction process". An estimated 25 percent to 50 percent reduction in sulfuric acid usage with the use of the enzyme is expected.
