Detailed explanation-1: -Keratinases belong to a class of proteases that are able to degrade keratins into amino acids. Microbial keratinases play important roles in turning keratin-containing wastes into value-added products by participating in the degradation of keratin.

Detailed explanation-2: -Keratinases (EC 3.4.-.-) are a group of hydrolytic enzymes that can catalyze the degradation of keratin. These keratinolytic enzymes are secreted by different types of microorganisms found in soil, water and on various keratin-rich sources.

Detailed explanation-3: -Enzymatic hydrolysis of insoluble feather keratin using the keratinase enzyme from the poultry sector can be utilized to make adhesives, livestock feed, fertilizers, coatings, or uncommon amino acids such as serine, cysteine, and proline. It is a protease enzyme that degrades keratin selectively.

Detailed explanation-4: -Keratin can be extracted using several methods such as chemical hydrolysis, enzymatic and microbial treatment, dissolution in ionic liquids, microwave technique, steam explosion technique and thermal hydrolysis or superheated process.
