Xylanase
The major role of Habio Xylanase is to eliminate anti-nutrient effect in animal feed and enhance the digestibility of feed, which increase utilization of unconventional feedstuffs, reduce feed costs and improve feed efficiency.
Definition of Activity
One unite (U) of xylanase is defined as the quantity of enzyme, which liberates 1μmol of reducing sugar from 5.0mmol/L xylan at 37℃ and pH5.5 in 1min.
Anti-nutrient Effect of Xylan
Arabinoxylan (AX) belongs to non-starch polysaccharide (NSP), is one kind of hemicellulose that exists in many plant feed. Based on the solubility, it can be divided into WEAX (Water-extractable Arabinoxylan, around 25%-30%) and WUAX (Water-unextractable Arabinoxylan, around 70%-75%).

1. Increasing viscosity of the chyme in gastrointestinal tract,reducing the interaction of nutrient and endogenous enzymes, thus slowing down the rate of diffusion of nutrients.
2. Augmenting the chyme moisture and increasing harmful microbial fermentation in hindgut, thus lowering nutrient efficiency and causing diarrhea.
3. Combining xylan with digestive enzymes (such as intestinal trypsin, lipase) and bile acid, thus reducing the activity of endogenous digestive enzymes in the animal intestinal tract and affecting digestion.
4. Nutrients (starch, protein, etc.) are enwrapped by WUAX, thus reducing the nutritional value of feed.
Product Features
1. Better thermostability than general fungal xylanase. The relative enzyme activity remains over 80% at 80℃ of pelleting temperature.
2. High proportion of endo-xylanase, high efficiency of enzymolysis.
3. A broad pH range of activity, thus helping play a role in the gastrointestinal tract more effectively.
4. Complete degradation of xylan can be done not only in WEAX, but also in WUAX, and further release nutrients enwrapped in cell wall.
Products Functions
1. Degrading xylan to xylooligosaccharide specifically, thus decreasing the chyme mucosity.
2. Balancing intestinal flora to improve animal immunity and reduce diarrhea ratio.
3. Increasing the diffusion rate of endogenous digestive enzymes, thus improving the nutrients digestibility.
4. Breaking down the structure of cell walls and releasing the nutrients inside, thus increasing the nutrients utilization efficiency of feed raw materials.
5. Improving and ensuring the feed quality.
6. Improving the animal production performance to increase customer profits.
