Abstract: Cellulases mainly include three categories: exocellulase, endocellulase and β-glucosidase. Among them, exocellulase is widely used in various industrial production because of its high activity, good tolerance and wide sources. Based on this, the classification, sources and biochemical characteristics of exocellulase were mainly expounded, and the new technologies related to the screening of exocellulase and the analysis of its hydrolysate were introduced. The application progress of exocellulases in paper industry, food processing industry, pharmaceutical industry, textile industry, energy regeneration and other industrial fields was summarized, in order to promote the further study and industrial application of exocellulases.

Key words: exocellulases, biochemical characteristics, industrial application
