Cellulase（ β- 1,4-glucan-4-glucan hydrolase) is the general name of a group of enzymes that degrade cellulose to produce glucose. It is not a monomer enzyme, but a multi-component enzyme system with synergistic effect. It is a composite enzyme, which is mainly cut by exonuclease β- Glucanase, endonuclease β- Glucanase and β- Glucosidase, and xylanase with high activity. Acting on cellulose and products derived from cellulose. Microbial cellulase is of great significance in transforming insoluble cellulose into glucose and destroying cell wall in fruit and vegetable juice, so as to improve the yield of fruit juice.

1. Cellulase is a kind of enzyme, which plays a biocatalytic role in the decomposition of cellulose. It is a protein that can decompose cellulose into oligosaccharides or monosaccharides.
2. Application of cellulase in livestock and poultry production
Common livestock and poultry feeds, such as grains, beans, wheat and processing by-products, contain a lot of cellulose. Except that ruminants can use part of cellulose with the help of rumen microorganisms, other animals such as pigs, chickens and other monogastric animals cannot use cellulose.
