Utilization of Enzymes in Production of Biogas: A Review

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, thus in this study we will add enzymes which will hydrolise protein at greater rate which can increase the production or produce energy and gas at low waste or dung. For this study we will introduce hydrolytic enzymes in a premixing chamber prepared to mix the dung and waste with the enzymes properly for its dilution. In this paper we are presenting literature review related to utilization of enzymes in production of biogas reviewing publications, journals and Google citations.
