PRODUCT DESCRIPTION

  • Alkaline protease JP-25 is a powder form preparation produced from Bacillus licheniformis through submerged fermentation, extraction and refining process.
  • It can efficiently catalyze the hydrolysis of proteins under alkaline conditions (pH 9-12). It is suitable for leather hair removal and silk degumming.

 

  • Use of JP-25 in leather processing can  simplify the process of leather hair removal, shorten processing time, improve quality of the finished products, increase leather yield, also suitable for pretreatment in silk degumming.
  • Use of JP-25 in silk degumming enables the following benefits: effectively removal of silk sericin without damage to the fibroin,enable silk fleeciness and lustrous, soft and smooth surface
