Product Introduction:

Dextranase: β-glucanase (β-1,3-1,4 glucanase). Manufactured by immersion fermentation of strain Bacillus Lichenifomis, this enzyme is an endonuclease that specifically acts on 1,3 and 1,4 glycosidic bonds of β-glucan to produce 3-5 glucose unit oligosaccharides and glucose is.

Dextranase can effectively break down β-glucan in the endosperm cell wall of wheat and grain plants and can be used in feed to reduce the content of non-starch polysaccharides (NSPs) and anti-nutritional factors and improve nutrient absorption by: Increase livestock and poultry, livestock poultry growth rate and feed conversion efficiency.

Used in beer brewing to lower the viscosity of wort, improve filtration performance, increase malt dissolution rate, prevent beer turbidity and stabilize beer quality.

The chemical properties of Dextranase:

Dextranase can break down high-molecular viscous glucans into low-viscosity isomaltose and isomaltotriose. The 1,3-β- and 1,4-β-glycosidic bonds of β-D-glucan are hydrolyzed to oligosaccharides and glucose. Suitable pH values ​​for action: 6.0-6.5 for bacterial production, 4.0-4.5 for mold production.

In general, it is stable at pH 6-9, e.g., when kept at pH 8.0 and 35 °C for 3 hours, the activity of Dextranase remains essentially unchanged, and when 45 °C is reached, the activity decreases by about 20. % and at 50°C it decreases to 70%. When calcium ion is present in aqueous solution, it is very stable and heat resistance is increased. Glycerin helps to prevent activity deterioration, and it is most effective when it contains 40~60%.

Surfactants may decrease activity. Dextranase is an off-white amorphous powder or liquid that can be added with carriers and diluents. It is soluble in water but basically insoluble in ethanol, chloroform and ether.

Uses of Dextranase:

  1. Increase the viscosity of Yumi.
    • Dextranase cannot be broken down by digestive enzymes secreted by single gastric animals. After dextranase is dissolved in water, it can hold water several times its own weight, making the chyme into a colloidal state, increasing the viscosity of chyme, slowing the circulation of chyme in the digestive tract, and reducing the intake of chyme. . Livestock and poultry quantity.
    • Dextranase can bind digestive enzymes such as proteases, amylases and lipases in the digestive tract, preventing these enzymes from reacting with substrates and reducing the activity of digestive enzymes.
    • The increase in viscosity interferes with the ability of the intestinal lactate to mechanically mix, affects the movement of digested nutrients to the intestinal mucosa, and reduces the rate of digestion and absorption of nutrients.
  2. Impeding the release of nutrients
    • Dextranase is a structural non-starch polysaccharide found in plant cell walls. Dextranase and cellulose, hemicellulose, lignin and small amounts of extensin are crosslinked via covalent or secondary bonds, macromolecular nutrients are tightly encased in plant cell walls, and nutrient and digestive enzyme physical barriers are formed. It interferes with the contact between nutrients and digestive enzymes, thereby lowering the feed utilization rate.
  3. Alter the gut microbiome
    • When the digestibility of feed nutrients is reduced, nutrients accumulate in the gut. Nutrient-rich chyme is an ideal medium for bacteria. The decrease in the rate of chyme passing through the digestive tract provides favorable conditions for the reproduction of bacteria, especially pathogenic ones.
    • The proliferation of a large number of harmful microorganisms creates an imbalance of intestinal microflora, stimulates the thickening of the intestinal mucosa, damages microvilli, increases the rate of animal diarrhea, and affects animal health. It also inhibits animal growth.
