ALKALINE PROTEASE DJP-3000

Alkaline protease DJP-3000 is produced from Bacillus licheniformis strain through submerged fermentation, extraction and purification. DJP-3000 can catalyze protein hydrolysis under alkaline conditions. It is suitable for food and beer industry, and can also be applied to leather tanning, silk glue removal and detergent production.
