DELTAZYM® GA L-E5 glucoamylase is obtained from a classical strain of Aspergillus niger designed to provide optimum ethanol yields in fuel ethanol production resulting in cost performance benefits. DELTAZYM® GA L-E5 glucoamylase is used to saccharify liquefied mash from various substrates including corn, wheat, milo, barley and cassava. It can be used in simultaneous saccharification fermentation (SSF) processes by adding directly to the fermentor with yeast.
DELTAZYM® GA L-E5 enzyme product produces glucose from liquefied starch in the fuel ethanol production process. It is an exo-1,4-α-D-glucosidase that hydrolyzes the 1,4-linkages in starch at a lower rate and also splits the branched 1,6-α-D-glucosidic linkages, making it an effective enzyme in the processing of both amylopectin and amylose starches. The product also contains acid α–amylase and lysophospholipase side activities that are specifically formulated to enhance ethanol yield. DELTAZYM® GA L-E5 enzyme product has extremely low levels of transglucosidase limiting repolymerization of glucose units. Source
