Description générale

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

Application

Cellulase from Aspergillus sp. has been used to degrade cello-oligosaccharides into glucose during the analysis of BBC (bioabsorbable bacterial cellulose) biodegradability.[1] The enzyme has also been used in photon correlation spectroscopy to study its effects on unfiltered beer samples. The parameters evaluated in this spectroscopic analysis were the size of suspended particles, flow rate and haze stability.[2]

Actions biochimiques/physiologiques

Cellulases are enzymes that hydrolyze cellulose, a linear polymer of anhydroglucose units linked together by β-1,4-glycosidic bonds, to glucose. Endo-β-D-glucanase is one of the major component enzymes of the cellulase complex. It catalyzes the hydrolysis of cellulose by randomly splitting the sugar residues within the molecule. Exo-β-D-glucanase and β-glucosidase can synergistically convert cellulose into glucose and hence are used on an industrial scale.[3]
