Abstract

In India as well as in the world, poultry is fast growing areas of the livestock sector. Keratinous waste such as hair, wool and feather are very difficult to deal with in solid waste management derived from poultry which richest source of recalcitrant protein known as keratin. Various zero-waste approaches were there for utilization of keratinous waste in to keratin. Physical, chemical, and biological treatment are used it. This review is focused mainly on the biological treatment and centered to the exploitation of solid waste in to valuable keratin protein. Biological treatment uses the different microorganism’s strains. Mainly serine protease and metalloprotease family contain most valuable as well as most of the microorganisms which is called as keratinolytic microorganism strains. Keratin protein obtained from the waste is useful in pharmaceutical and cosmeceutical industries. Ultimately approach of biological treatment having great roll compared to chemical and physical treatment as they consume high amount of energy for optimization of chicken feathers into keratin. Skincare and whitening products bring in billions of dollars for the pharmaceutical and cosmeceutical businesses. Keratin generated from the solid waste will be a possible contender for keratin-based skincare products in this context.
