Abstract:

Apparently, the catalytic reaction of sugar is of great significance to human life activities and industrial production. In recent years, the rapid development of the multienzymes co-immobilization technology provides a green and efficient research tool for the catalytic reaction of sugar. Under this background, combined with the multienzymes cascade reaction in sugar catalysis, this paper systematically expounds the traditional and new methods of multienzymes co-immobilization, and illustrates its respective principles and advantages as well as disadvantages. On this basis, this paper further introduces the wide applications of multienzymes co-immobilization technology in sugar catalysis in detail, such as starch hydrolysis, cellulose utilization and functional sugar synthesis. In accordance with the related research results, it is indicated that the multienzymes co-immobilization technology not only has a series of remarkable characteristics including high efficiency catalysis, strong stability and easy separation, but also can give full play to the advantages of synergistic catalysis among multienzymes, thus greatly promoting the catalytic reaction of sugars. In the last, this paper analyzes some of the problems and challenges facing multienzymes co-immobilization technology, puts forward some research thoughts and methods for solving these problems，and looks forward to its development prospects.

Key words: multienzymes co-immobilization, sugar catalysis, cascade reaction, synergistic effect
