What is the Cellulase Enzyme?

Cellulase enzyme powder refers to a group of enzymes that degrade cellulose. Cellulase enzyme is a complex enzyme system consisting of a variety of hydrolytic enzymes, mainly from fungi and bacteria. According to the different functions of each enzyme, it can be divided into three categories:

1. Glucan endonucleases enzymes, which generally act on the amorphous region of cellulose.

2. Glucan exonuclease enzymes, which acts on the end of cellulose linear molecule, hydrolyzes the beta-1,4 glycoside bond and cuts one cellobiohydrolase molecule at a time, so it is also called cellobiohydrolase.

3. Beta-glucanase enzyme (beta-1,4-glucosidase, E.C3.2.1.21, abbreviated as BG) hydrolyzes cellobiose into glucose molecules.
The mechanism of cellulase enzymes is that endoglucosidase attacks the non-crystalline region of cellulose enzyme first to form a new free end for exogenous cellulose enzyme, then exogenous cellulose enzyme cuts down the cellobiose unit from the non-reductive end of the polysaccharide chain, and then hydrolyzes the cellobiose unit by beta-glucosidase to form glucose. It is generally believed that the synergism is proportional to the crystallinity of enzymatic hydrolysate. When the mixing ratio of enzymatic components is similar to that of each component in the fermentation broth of fungi, the synergism is the greatest, and there is synergism between endonucleases and exonucleases produced by different bacterial sources. Nevertheless, science is still in the process of exploration, and its mechanism of action has not been finalized.

Under such background, Xiongjin Biotechnology Co., Ltd. screens excellent protoplasts and produces cellulase by submerged liquid fermentation, which is widely used in food, feed and textile industries. Therefore, Xiongjin Group is absolutely your ideal cellulase enzyme supplier!
