Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to a cellulase-producing bacterium and its application. The cellulase-producing bacterium involved in the present invention has better enzyme-producing ability of cellulase and hemicellulase. Background technique

[0002] Cellulose is the most abundant carbohydrate in nature, and it is a kind of renewable resource and energy. However, cellulose is difficult to be decomposed and utilized. How to convert cellulose into resources and energy that can be directly used is a difficult problem in front of people. There are two ways to degrade cellulose: chemical method and biological method. The chemical method has poor specificity, low purity, and pollutes the environment, while the biological enzyme method can overcome these shortcomings. attention.

[0003] Cellulase is a general term for a group of enzymes that can degrade cellulose Beta-1,4-glucosidic bonds and turn cellulose into cellob...
