| Hemicellulase is an enzyme complex useful for the isolation of plant protoplasts, biomass conversion, carbohydrate research, liquid food clarification and cell dissociation. A. niger converts cellulose to glucose via multi-enzymatic hydrolysis of beta-D-1,4-glucans, xylans and hemicellulosic polymers. Contains a mixture of exo- and endo-glucanases. Exhibits a high degree of selectivity for galactomannan polysaccharides. CAS No: 37288-54-3 Source: Aspergillus niger Form: Supplied as a light tan to tan powder. Contains maltodextrin. Loss of Drying: 10% Solubility: Readily soluble in water. Enzyme Activity: 400,000 HCU/g. Contains trace amounts of alpha-amylase, beta-galactosidase, pectinase, protease and xylanase activity.
