Cellulase is one of the important industrial enzymes with a wide range of applications.

Cellulase is the general name for a group of enzymes that degrade cellulose to generate glucose. It is one of the subdivisions of complex enzymes and mainly consists of exoglucanase, endoβ-glucanase, β-glucosidase, etc. It is the fourth largest industrial enzyme after glucoamylase, amylase and protease, and is called “industrial monosodium glutamate”.

Cellulases are widely found in organisms in nature, including bacteria, fungi, plants, animals, etc. The current main methods for producing cellulase include solid fermentation, which refers to culturing cellulase-producing strains in a solid substrate containing cellulose, and adjusting conditions such as temperature and humidity to allow the strains to grow and reproduce, ultimately producing cellulose. Enzyme method; liquid fermentation method refers to the method of cultivating cellulase-producing strains in a liquid medium, allowing the strains to fully grow and reproduce through stirring and aeration, and finally producing cellulase. Among them, the strains used to produce cellulase mainly include Trichoderma, Aspergillus niger, Aspergillus, etc.

Cellulase has a wide range of applications, and its main application areas include textiles, papermaking, food, feed, etc. In the field of feed, cellulase is mainly used as a feed additive to supplement the lack of endogenous enzymes in animals, improve the digestion and absorption of nutrients by animals, and improve the relationship between animal digestive tract flora. In the field of textiles, cellulase is mainly used in cotton. Fabric refining processing, cellulose fiber fabric softening and polishing finishing scenarios play a role in removing natural impurities in fabrics and improving fabric softness; in the food field, cellulase is mainly used in fruit and vegetable processing, juice processing, beverage and soy sauce processing, etc. , playing the role of decomposing impurities and turbid components, enzymatically hydrolyzing raw materials, etc.

According to the “China Cellulase Industry Market Monitoring and Future Development Prospects Research Report 2023-2028” released by the Industrial Research Center , currently with the rapid development of the downstream market, the scale of my country’s cellulase market continues to expand. In 2022, my country’s cellulase market size will exceed 5 billion yuan, with a year-on-year growth of approximately 6.5%. At present, the main cellulase manufacturers in my country include Hubei Liye Biological Products, Shandong Longda Bioengineering, Zhongrong Technology Co., Ltd., Shandong Longli Ethanol Technology, Fengyang Chiyuan Biotechnology Development, Ningxia Yizheng Bioengineering, and Hunan Lierkang Biotech. Co., Ltd., Nanning Pangbo Bioengineering, Hebei Yuanda Zhongzheng Biotechnology, etc., there are many companies.

Industry analysts said that cellulase is one of the main industrial enzymes and is mainly produced by fermentation. , playing an important role in textile, papermaking, food, feed and other fields. In recent years, against the background of the rapid development of the downstream market, the scale of domestic cellulase has continued to expand, and the industry has shown good development prospects. At present, most companies in our country have entered the cellulase market. Under the fierce market competition in the future, local companies need to continue to develop advanced fermentation processes and continuously improve their competitiveness.
