Abstract:

Protease enzymes are the enzymes that hydrolyse proteins. Each type of protease enzyme breaks specific kind of peptide bonds. These enzymes are of great commercial importance contributing to more than 40% of the world’s commercially produced enzymes. Approximately 50% of the enzymes used in industrial processes are proteolytic enzymes. Different substrates used for the protease enzyme production add to the cost and hence makes the process very costly. Different wastes like wheat bran, rice bran, vegetable waste and sweet potato residue are being explored as substrate to be utilized for enzyme production. However, the present review paper mainly focuses on the biodigested slurry either from cattle dung or poultry droppings based gas plant, which has sufficient nutrients and can be used for protease enzyme production. Poultry dropping and cow dung based biodigested slurry has been used first time as a substrate for protease production which may not only pertains to its value addition but will also cures environmental pollution by managing large amount of slurry discharge from biogas plant.
