Acid Protease AP-10

Product Description

Acid Protease AP-10 is produced from robust strains of Aspergillus niger through submerged fermentation and extraction and refining technique. It can catalyze protein hydrolysis under acidic condition (pH 2.5~4.0) thus is applicable to hydrolyze plant and animal proteins under acidic conditions, such as proteolysis of animal and plant.
AP-10 is suitable for the production of leather. 

Product Characteristics
Declared Enzyme:       Acid Protease
Systemic Name:  EC  
Activity: 100,000 U/g (Minimum)
Appearance: Pale brown powder
Moisture:  8% (Maximum)
Effect of pH
AP-10 is stable with pH from 2.5 to 4.0. It will be inactivated quickly at pH below 2.5 or above 4.0. The optimal pH is 3.0 at the temperature of 40°C.

Effect of Temperature 

Effective temperature is from 30 to 50ºC at pH around 3.0; Optimal temperature is 40ºC. It is stable below 40ºC, unstable above 50ºC and inactivated quickly above 60ºC.

Effect of Metal Ions

The enzyme activity is activated by Mn2+, Ca2+ and Mg2+, and inhibited by Cu2+, Hg2+ and Al3+.
Storage & Shelf-life 
  • Typical shelf-life is twelve months provided this product is stored at 0∼25°C in its original packaging, sealed and unopened, protected from direct sunlight.
  • Prolonged storage and/or adverse conditions such as higher temperatures may lead to higher dosage requirement, therefore should be avoided.
