Preliminary Study on Keratinase from Two Indonesian Isolates
Animal Production: Indonesian Journal of Animal Production, 2010 Keratinases (E.C.3.4.99.11) constitute a group of enzymes capable of disrupting the highly stable keratin structure consisting of disulphide, hydrogen, and hydrophobic bonds in the form of α-helices and β-sheets B. licheniformis MB-2 and Bacillus sp. MTS

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.
