Detailed Dextranase: Fungal Dextranase For Sugar Cane Industry Description:
Dextranase: Fungal Dextranase for Sugar Cane Industry
Specification: Type: Enzyme Preparations ;
Dextranase enzyme
When the dextran level in sugar cane juice exceeds approximately 1000 mg/kg (Brix basis), this high molecular weight polysaccharide increases the viscosity of the sucrose solutions in the milling and refining processes. Dextran interferes with insoluble particle aggregation and settling, filtration rates, evaporation and boiling rates, and overall process control. During evaporation the dextran concentration increases which interferes with crystal formation and crystal separation. This increases sucrose loss to the final molasses. Processing capacity and yields are decreased and plant shutdown may be required for equipment cleaning.
The application of Dextrasol can alleviate the processing and product quality problems associated with dextrans in sugar milling and refining.
Description
Dextrasol, a fungal dextranase (E.C. 3.2.1.11, 1,6-alpha-D-glucan 6-glucanohydrolase) is obtained by the controlled fermentation of modified fungal strain. The enzyme is an endo-dextranase capable of randomly hydrolyzing the interior alpha-1,6-glucosidic linkages of dextran and its degradation products. This activity rapidly reduces the viscosity of dextran solutions, initial hydrolysis products of Dextrasol dextranase are soluble polysaccharides and oligosaccharides of varying lengths. Prolonged hydrolysis with Dextrasol results in the formation of glucose and lower levels of isomaltose and isomaltotriose.
Dextrasol has a high degree of specificity for the interior bonds of the dextraii polymer versus the end sugar unit. Dextrasol also has a pH optimum appropriate for application to mixed juice and no invertase activity.
