Proteases are one of the most important classes of industrial enzymes, accounting for about 60% of the total enzyme sales worldwide [5]. Proteolytic enzymes could be obtained from microorganisms, animals, and plants. Bacterial proteases are the most significant group of industrial enzymes compared to animal and fungal proteases, and recent estimates indicate that they account for about 35% of the total microbial proteases currently employed in the detergent industry [6].
