Abstract
As a kind of efficient biocatalyst, bioenzyme has a unique advantage in chemical industry production. The traditional chemical catalysis method has some problems, such as harsh reaction conditions, poor selectivity and environmental pollution, while the biological enzyme catalysis shows mild reaction conditions, high specificity and environmental friendliness. The purpose of this study is to explore the application of biological enzymes in chemical industry production in order to improve production efficiency and achieve green and sustainable development. By screening and reforming specific biological enzymes, immobilization technology is adopted to improve their stability and reusability, and the reaction system is optimized with modern bioengineering technology. A variety of typical chemical products were selected as research ob jects, and reaction paths were constructed based on different biological enzymes. The results showed that the conversion and selectivity of the target products could be significantly improved by the modified enzyme, the yield of some reactions was increased by more than 30%, and the by-product generation was greatly reduced. In addition, the immobilization treatment effectively extends the service life of biological enzymes and reduces the cost input. This research innovatively combines directional evolution technology and rational design, and successfully obtains a new type of biological enzyme with better performance, provides a new idea and technical means for chemical industry production, promotes the wide application of biocatalogical technology in the industrial field, and realizes a win-win situation of economic and environmental benefits.
