A powder protease can hydrolyze plant and animal proteins under acidic conditions, capable to destroy the scales on the surface of wool fibers, thus prevent wool from shrinking and enable it easier for dyeing.
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.

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 ON ENZYME ACTIVITY 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∼10°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.
