Description

Application

• Novel biotechnological formulations of cysteine proteases, immobilized on chitosan. This study focuses on the development and characterization of innovative biotechnological formulations of cysteine proteases including papain, which are immobilized on chitosan to enhance their stability and activity. Such immobilization has significant implications for biopharmaceutical manufacturing processes, offering potential advancements in the stability and efficiency of biotechnological applications (Holyavka et al., 2021).


• A novel aspartic protease from Rhizomucor miehei expressed in Pichia pastoris and its application on meat tenderization and preparation of turtle peptides. While primarily focusing on a novel aspartic protease, this research discusses comparative proteolytic activities including those of papain, highlighting its utility in improving the tenderness and quality of meat products, thus supporting its industrial application in food processing and life science manufacturing (Sun et al., 2018).


• Comparison of the proteolytic activities of new commercially available bacterial and fungal proteases toward meat proteins. This comparative study assesses the efficacy of various proteases including papain in the breakdown of meat proteins. Papain′s effective proteolytic action is beneficial for its use in industrial and research settings, particularly in food science applications where efficient protein digestion is critical (Ha et al., 2013).
