TL;DR: The immobilized keratinase exhibits improved stability, thereby increasing its potential for use in numerous applications and displaying a higher level of heat stability and an increased tolerance toward acidic pHs compared with the free keratin enzyme.
Abstract: 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. During a continuous reaction at 50(deg)C, the immobilized keratinase retained 40% of the original enzyme activity after 7 days. The immobilized keratinase exhibits improved stability, thereby increasing its potential for use in numerous applications.

TL;DR: Bacillus licheniformis O.W.U. 138B and 88B and other bacterial strains capable of degrading feathers isolated from wild birds, are disclosed in this article.
Abstract: Bacillus licheniformis O.W.U. 138B and 88B and other bacterial strains capable of degrading feathers isolated from wild birds, are disclosed. The strains and the keratinases produced by these strains are useful for degrading waste feathers produced by commercial poultry processing; producing animal feed, fertilizer, or natural gas from poultry waste; and cleaning of certain fabrics.
