The multi-enzyme cascade reactions are an important biotechnology in modern industrial processes. However, the separation and recovery of enzyme is a tedious and laborious work. Therefore, enzyme immobilization is the key issue in practical applications. The immobilized multi-enzyme could improve the cascade activity of enzymes through the substrate channel, and easily separated support materials also benefit the stability of the enzyme and ease its recovery and reuse. This review focuses on the recent researches of immobilized multi-enzyme strategies and easily separated support materials, including different strategies of multi-enzyme complexes, immobilized enzymes and easy-to-separate carrier. Moreover, the practical applications of immobilized multi-enzymes in food production and biosensor fields are summarized. The development prospects and trends of immobilized multi-enzyme catalytic reactions are discussed.
