Description_x000D_ General description_x000D_ We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research._x000D_ Application_x000D_ Cellulase from Sigma has been used to degrade cello-oligosaccharides into glucose; to study the biodegradability of bioabsorbable bacterial cellulose (BBC) material._x000D_ Cellulase from Trichoderma reesei has been used in a study to assess the differential regulation of the cellulase transcription factors XYR1, ACE2, and ACE. Cellulase from Trichoderma reesei has also been used in a study to investigate the liquefaction of hydrothermally pretreated wheat straw at high-solids content._x000D_ Packaging_x000D_ 2500, 5000, 10000 units in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Cellulases are enzymes that hydrolyze cellulose to glucose. Cellulase is used to study the development of occupational asthma in the detergent, pharmaceutical, baking, and enzyme production industries. Cellulase is added to detergents to improve cleansing properties. It is also applied in the biodegradation of paper products such as foolscap paper, filter paper, newspaper and office paper as well as microcrystalline cellulose._x000D_ Unit Definition_x000D_ One unit will liberate 1.0 μmole of glucose from cellulose in one hr at pH 5.0 at 37 °C (2 hr incubation time)._x000D_ Preparation Note_x000D_ Dissolves in sterile deionized (DI) water in the presence of 0.15% polyhexamethylene biguanide (PHMB) at 5 mg/mL concentration._x000D_ Other Notes_x000D_ View more information on enzymes for complex carbohydrate analysis at www.sigma-aldrich.com/enzymeexplorer
