Product Description
Dextranase, called α-glucanase(CAS No.9025-70-1, EC3.2.1.11).
It’s a high-yielding strain from Chaetomium gracile screened by mutagenesis, which is through liquid deep fermentation extract from refining.
It’s widely used in the field of sugar industry, oral care and etc..
Action Principle
Dextranase is a hydrolase for specificity splitting decomposition α-1, 6-glucoside linkages of dextran molecule, which outcome production are mainly isomaltose, isomalto-oligosaccharides and glucose.

Application Method
Sugar industry: In the sugar industry, leuconostoc mesenteroides streptococcus and other microorganisms are through secretion glucansucrases catalyze sucrose to glucose, glucose further polymerized to form dextran. The dextran is a high molecular weight polysaccharide polymer, and the type of glycosidic linkage is mainly α-1, 6 glycosidic bond. The existence of dextran will have serious impact on sugar production, obviously increasing the viscosity of sugar, reducing the sugar filtration, so that crystallization of sucrose generate abnormal morphology crystals, increase the sugar costs while affect product quality. The use of dextranase can effectively improve the speed of heating cane juice, shorten time to clarify and crystallize, to eliminate the adverse impact of crystallization, thereby improve the production efficiency and yield of sugar. Use of enzyme activity 30000u/g of the product, contains 1000ppm dextran concentration in the cane juice, add 3ppm liquid enzyme, the effect of hydrolysis as below:
Other Application:
It also can be widely used to prepare small molecule dextran.
