Alkali Protease

1. Production introduction

　　Alkaline protease is a kind of enzyme excreted from alkalophilic bacillus, it is a protein hydrolase extracted from Bacillus licheniformis by fermentation, it can hydrolyze protein peptide bond under alkaline condition, and it has strong ability to decompose protein. It is widely used in detergent, food, medical, brewing, silk, tanning and other industries.
