[摘要]：The application of enzyme technologies to industrial research, development, and manufacturing has become a very important field. Since the production of crude rennet in 1874, several enzymes have been commercialized, and used for therapeutic, supplementary, and other applications. Recent advancements in biotechnology now allow companies to produce safer and less expensive enzymes with enhanced potency and specificity. Antioxidant enzymes are emerging as a new addition to the pool of industrial enzymes and are surpassing all other enzymes in terms of the volume of research and production. In the 1990s, an antioxidant enzyme-superoxide dismutase (SOD)-was introduced into the market. Although the enzyme initially showed great promise in therapeutic applications, it did not perform up to expectations. Consequently, its use was limited to non-drug applications in humans and drug applications in animals. This review summarizes the rise and fall of SOD at the industrial level, the reasons for this, and potential future thrust areas that need to be addressed. The review also focuses on other industrially relevant aspects of SOD such as industrial importance, enzyme engineering, production processes, and process optimization and scale-up. |
