Isolation and Identification of Alkaline Protease Producing Bacteria from Municipal Solid Wastes in Bangladesh

Proteolytic enzymes are found in all living organisms. Proteases [EC 3.4.2124] are complex enzymes which are responsible for the hydrolysis of protein molecule (proteolysis). The products of proteolysis are protein and peptide fragments and free amino acids. Currently, most enzymes used in industrial processes are hydrolytic and are used for the degradation of various natural substances. This is the most important groups of enzymes which occupy a pivotal position in industrial biotechnology. They constitute 60% of the total enzymes used in various industries and account for at least a quarter of the total global enzyme production. Besides, enzymes have fascinated the world attention due to their broad range of uses in many fields and are gradually substituting the use of harsh chemicals in various industrial processes. More than 3000 different enzymes have been identified and most of them have biotechnological and industrial applications.The goal of this study was to isolate and screen the alkaline protease producing bacteria from protein based municipal wastes and to Identify the alkaline protease producing bacteria based on molecular identification of bacterial isolates by 16SrDNA sequencing.
