The environment and its role on human lives is an important phenomenon (1). Million tons of feathers generated annually by the livestock industry leads to troublesome environmental pollution and wastage of protein-rich reserve (2). The poultry feathers are dumped, used for land filling and incinerated or buried, which involves problems in storage, handling, emission control and ash disposal (3). Discarded feathers also cause various infections including chlorosis, mycoplasmosis and fowl cholera (4). Feather contains over 90% of crude protein in the form of keratin (2). Keratin is an insoluble fibrous protein which is rich in beta helical extensively cross-linked by disulfide, hydrogen and hydrophobic bonds (3). Hence, it is extremely resistant to degradation by common proteolytic enzymes such as trypsin, pepsin, and papain.
