Keratinases are proteolytic enzymes and are able to degrade insoluble keratin substrates
Keratinases are proteolytic enzymes and are able to degrade insoluble keratin substrates (Brandelli, 2008) and find various application in developing cost-effective feather by-products for feed and fertilizers. Their application can also be extended to detergent and leather industries where they serve as special enzymes. Besides, they also find applications in wool and silk cleaning, leather industry, better dehairing potential of these enzymes has led to the development of greener hair-saving dehairing technology and personal care products (Onifade et al., 1998; Gupta and Ramnani, 2006; Brandelli, 2008; Sahni et al, 2015). Further, their prospective application in the challenging field of prion degradation would revolutionize the protease world in the near future. Few of these important applications are given below.
