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… CONTINUE READING
