Mid-temperature alpha amylase, textile desizing enzyme
Application
An Alpha-Amylase reduces processing costs without any damage to the fibers in textile processing.
Description
Alpha-Amylase BAA-200 contains a hydrolyzing alpha-amylase made from submerged culture of Bacillus subtilis var. Through extraction and refining processes. It is a kind of endoamylase, which rapidly decreases the viscosity of the gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-1, 4 glycosidic bonds and produces soluble dextrins and oligosaccharides.
The powerful amylase activity of BAA200 breaks down starch to soluble polysaccharide in the textile which can easily be washed out. It enables the following benefits for textile industry: Mild, non-hazardous operating conditions, no damage to the fiber, considerably reduced water consumption, workload and processing costs.
Product Characteristics
Declared Enzyme: Alpha-Amylase
Systematic Name: EC 3.2.1.1, 1, 4-alpha-D-glucan glucanohydrolase
Activity: 2, 000 U/ml (minimum)
Appearance: Light to dark brown liquid
Product pH: 5.5 to 7.0
Specific gravity: 1.15 to 1.25 g/ml
Optimum pH:6.0~6.5
stable pH range:6.0-7.0
Effect of Temperature
Optimum temperature ranges from 60 to 90º C. At a temperature ranges from 70 to 90º C, the reaction speeds up when the temperature rises while the enzyme inactivation also speeds up.
Effect of pH
Optimum pH 6.0~6.5, stable pH range 6.0~7.0, inactivated dramatically with pH below 5.0.
Optimum temperature ranges from 60 to 90º C. At a temperature ranges from 70 to 90º C, the reaction speeds up when the temperature rises while the enzyme inactivation also speeds up.
Effect of Calcium
Calcium ion plays a protective role for the stability of enzyme activity. The enzyme activity may disappear completely without the presence of calcium ion. The pH range of enzyme activity is broadened with the presence of calcium and narrowed without it.
Dosage
Protection salts should be added (0.025% calcium chloride, 0.4% sodium chloride) befor adding BA-200. Typical dosage rate is 0.5 to 3 ml per liter of water. Exact dosage level should be determined after test according to the actual situation.
