Alkaline Protease
Brief Introduction:
The Alkaline Protease is a solid enzyme produced by submerged fermentation from Bacillus licheniformis according to the specification of GB/T23527-2009 (China). It is widely applied in detergent, leather depilation and softening, silk degumming, toothpaste, soap, heparin sodium, chondroitin and etc.
Definition of Activity:
One gram of solid Alkaline Protease powder at 40°C and pH 10.5 hydrolyze casein in one minute to produce 1μg tyrosine is called one enzyme activity unit and marked with u/g.
Physical Properties:
This type of Alkaline Protease can efficiently hydrolyze the macromolecule protein into free amino acids.
