 AP-100L is a liquid proteolystic acid enzyme produced from 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.


Acid Protease AP-100L capable to destroy the scales on the surface of wool fibers, prevent wool from felting and enable easy dyeing.





  • 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.


  • AP-100L 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.

 Metal Irons:

  • The enzyme activity is activated by Mn2+, Ca2+ and Mg2+,
  • Inhibitors:  Cu2+, Hg2+ and Al3+.
