Product Overview


Feed additive keratinase enzyme disintegrate feather 


The keratinase is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. It’s a protease with broad specificity capable of degrading water soluble and insoluble proteins. It’s able to hydrolyze keratin efficiently into smaller peptides and amino acid, outperforming most non-keratin degrading proteases.

Keratin is commonly found in fur, feather, horn, hoof and fish scale. It contains high amount of cross-linked disulfide bonds and hydrophobic amino acids forming very tight structure, and is very resistant to proteolysis. Keratinase is unique in that it contains multifunctional potent enzymatic activities attacking disulfide links and peptide bonds, and thus depolymerizes keratin efficiently, increasing digestibility of feed containing protein with the similar structure.
