Proteases are hydrolytic enzymes which catalyze the cleavage of peptide bonds in other proteins into smaller peptide
fragments [1]. These enzymes account to 60 percent of total world enzyme market [2] and are ubiquitous in nature
thus occur in all living things such as plant, animal, microorganisms[3]. Extraction of proteases from plant and
animal sources require many steps and also results in low enzyme yield. Hence microbial source is preferred
because of their rapid growth and vulnerable to genetic manipulation [4,5]. Moreover, fungal strains offer more
advantages of utilization of low cost materials, high protease productivity and easy in the recovery of enzyme [6].
Proteases are classified as alkaline, acid and neutral proteases according to the range of pH at which they exhibit maximum activity.
