Hydrolysis of feather keratin by immobilized keratinase [PDF]
Applied and Environmental Microbiology, 1996 Keratinase isolated from Bacillus licheniformis PWD-1 was immobilized on controlled-pore glass beads. The immobilized keratinase demonstrated proteolytic activities against both insoluble feather keratin and soluble casein. It also displayed a higher level of heat stability and an increased tolerance toward acidic pHs compared with the free keratinase.

Hydrolyzing Proficiency of Keratinases in Feather Degradation [PDF]
Indian Journal of Microbiology, 2014 The keratinase degrade highly rigid, cross linked structural polypeptides with different efficiency depending on the type of source. Two newly isolated strains of Bacillus subtilis (RSE163 and RSE165; NCBI Accession no JQ887983 and JQ887982) were found to be efficient keratinase producers with unusual catalytic activity result in different ...

Determination of Keratinase Activity using Chicken Feather DMSO extract and its optimization with Response Surface Methodology [PDF]
E3S Web of ConferencesKeratinase is an enzyme capable of degrading keratin, exhibiting two activities: protease activity, which cleaves peptide bonds, and disulfide reductase activity, which reduces disulfide bonds (-S-S-). However, keratinase activity is often measured using
