Biological Enzyme Preparations

Cellulase (β-1,4-glucan-4-glucan hydrolase) is the general name for a group of enzymes that degrade cellulose to produce glucose. It is not a monomeric enzyme, but a multi-component group that acts synergistically. The enzyme system is a complex enzyme, mainly composed of exo-β-glucanase, endo-β-glucanase and β-glucosidase, as well as highly active xylanase. Acts on cellulose and products derived from cellulose. Microbial cellulase is of great significance in converting insoluble cellulose into glucose and destroying cell walls in fruit and vegetable juices to increase juice yield. Feed cellulase is an enzyme preparation specially used in animal feed. It can decompose the cellulose in the feed and improve the digestibility and nutritional value of the feed. The enzyme preparation usually consists of a variety of enzymes, including exo-β-glucanase, endo-β-glucanase and β-glucosidase, etc. These enzymes can work synergistically to effectively degrade cellulose.

Mesophilic amylase is an important enzyme product, which is usually extracted through fermentation of microorganisms such as Bacillus subtilis. This product has the characteristics of highly efficient starch hydrolysis, and can arbitrarily cut the starch molecules from the inside into long and short short bond dextrins and a small amount of low molecular sugars, thereby rapidly reducing the viscosity of the starch slurry and achieving liquefaction.

Feed grade alkaline protease is an enzyme preparation specially used in the feed industry and is a serine endoprotease. It can effectively improve the digestion and absorption rate of protein in feed and promote the growth and development of animals. Enzyme preparations used for feed processing have efficient protein degradation capabilities and perform better under weakly alkaline conditions.

Neutral protease feed grade is an enzyme preparation specially used in the feed industry, extracted and purified through biotechnological means. This product can effectively degrade the protein in the feed and convert it into small molecule peptides and amino acids that are easily absorbed by animals, thus improving the nutritional value and utilization of the feed.

Acid protease feed grade product is an enzyme preparation produced through microbial fermentation. It can effectively hydrolyze protein in feed under low pH conditions to generate amino acids and peptides, thereby improving the nutritional value of feed. The product is in powder or liquid form and is easy to mix evenly with feed.

Neutral protease food grade is an efficient, safe, non-toxic endoprotease with strong hydrolysis ability and wide range of action. It exists in the form of a light yellow solid powder and is manufactured through bioengineering technology, microfiltration, ultrafiltration membrane separation and vacuum freeze-drying technology. The product quality has reached food grade and pharmaceutical grade standards.

β-Glucanase is an enzyme preparation that can efficiently break down β-glucan in the endosperm cell walls of wheat and cereal plants. In the field of feed, it can significantly increase the nutritional value of feed and reduce the content of anti-nutritional factors, thereby improving the absorption of nutrients by livestock and poultry, increasing the growth rate and feed conversion efficiency of livestock and poultry.

β-Mannanase is a multifunctional growth-promoting agent that can promote the secretion of insulin-like growth factor IGF-I, promote protein synthesis, increase lean meat rate, and promote growth. β-mannanase (endo-1,4-β-mannanase) contains amylase, xylanase, cellulase, protease, pectinase, etc.; β-Mannanase is an enzyme preparation specifically used to degrade β-mannan and is usually used in feed production. It helps improve the digestibility of beta-mannan in feed and enhances the animal's ability to absorb it. It is developed using modern fermentation and enzyme engineering technology and combined with the physiological characteristics of livestock and poultry. It is a high-tech green biological additive.

Xylanase is an enzyme product whose main function is to hydrolyze xylan in wood fibers and break it down into xylose and other monosaccharide units. This enzyme is a key biocatalyst, particularly suitable for the efficient utilization of lignocellulosic resources.

Alpha-amylase is an enzyme product whose main function is to play a role in the hydrolysis of starch. It is an enzyme capable of hydrolyzing starch, specifically alpha-1,4-glycosidic bonds, thereby breaking down starch into smaller polysaccharide or monosaccharide units.

Cellulases are composed of three categories: endoglucanase (C1 enzyme); exoglucanase (Cx enzyme); β-glucosidase (ßG for short), also known as cellobiohydrolase. C1-enzyme acts on the surface of insoluble cellulose to cleave the crystalline cellulose chains and free the end portions of long-chain cellulose molecules, thereby making the cellulose chains easy to hydrate. Cx-enzymes mainly include endo-β-1.4 glucanase and exo-β-1.4 glucanase, which act on cellulose catalyzed by C1-enzyme to decompose β-1.4 glycosidic bonds. The former is to cleave the β-1.4 bond from any position inside the polymer, mainly producing cellobiose, cellotriose, etc. The latter acts on low molecular weight polysaccharides to free glucose from the non-reducing end. β-Glucosidase can further decompose cellobiose, cellotriose and other low molecular weight oligosaccharides into glucose.

Lipase (Lipase, glyceryl ester hydrolase) belongs to the carboxyl ester hydrolase class and can gradually hydrolyze triglycerides into glycerol and fatty acids. Lipase exists in fat-containing animal, plant and microbial (such as mold, bacteria, etc.) tissues. Including phosphatase, sterolase and carboxylesterase. Fatty acids are widely used in food, medicine, leather, daily chemicals, etc. Lipase is one of the important industrial enzyme preparations. It can catalyze lipolysis, transesterification, ester synthesis and other reactions, and is widely used in oil processing, food, medicine, daily chemical and other industries. Lipases from different sources have different catalytic characteristics and catalytic activities. Among them, the large-scale production of lipases with transesterification or esterification functions for organic phase synthesis is of great significance for the enzymatic synthesis of fine chemicals and chiral compounds.
