Biotechnological production and practical application of L-asparaginase enzyme.

L-asparaginase is a vital enzyme of medical importance, and renowned as a chemotherapeutic agent. The relevance of this enzyme is not only limited as an anti-cancer agent, it also possesses a wide range of medical application. The application includes the antimicrobial property, treatment of infectious diseases, autoimmune diseases, canine and feline cancer. Apart from the health care industry, its significance is also established in the food sector as a food processing agent to reduce the acrylamide concentration. L-asparaginase is known to be produced from various bacterial, fungal and plant sources. However, there is a huge market demand due to its wide range of application. Therefore, the industry is still in the search of better-producing source in terms of high yield and low immunogenicity. It can be produced by both submerged and solid state fermentation, and each fermentation process has its own merits and demerits. This review paper focuses on its improved production strategy by adopting statistical experimental optimization techniques, development of recombinant strains, through mutagenesis and nanoparticle immobilization, adopting advanced and cost-effective purification techniques. Available research literature proves the competence and therapeutic potential of this enzyme. Therefore, research orientation toward the exploration of this clinical significant enzyme has to be accelerated. The objectives of this review are to discuss the high yielding sources, current production strategies, improvement of production, effective downstream processing and therapeutic application of L-asparaginase.
