摘要

The poultry industry is one of the major revenue generating industries around the world.This industry generates a lot of wastes including huge amounts of chicken feathers,that are recalcitrant,thus,difficult to dispose of and have a negative environmental impact.The main methods of disposal of feathers are either incineration or dumping them with other waste materials that hinder their biodegradability by soil microorganisms.These methods are energy-intensive and also lead to the loss of valuable protein keratin that forms the major part of chicken feathers.Recently,biodegradation/metabolism of chicken feathers by microorganisms has been considered an excellent alternative for the disposal of keratin waste.Keratin degradation leads to the formation of free amino acids and soluble proteins that are a precursor of many valuable metabolites and value-added products.Thus,the present review deliberated on the importance of chicken feathers and also other keratin waste materials to be considered as an important bio-resource and their complete valorization into high-value chemicals and development of cost-effective technologies to convert poultry wastes into useful products.
