Acid β-mannanaseβ-mannan is a kind of hemicellulose which is most widely spread and has high content in plant except cellulose and xylan. It is a linear polymer formed by β-1,4-D- D-mannose, mainly glucose group, acetylgroup and galactose group, forming the main component of the cell wall of seed plants.β-mannan and its derivatives hinder nutrition absorption in feed, which leads to diarrhea in different degrees, and ultimately affects the growth and feed utilization of livestock and poultry. The anti-nutritional effect of mannan is the formation of gel 'mucus' after dissolving it in water, so as to improve the viscosity of chyme, reduce the contact between endogenous enzymes and nutrients in animals, slow down nutrient absorption by intestinal tract, and adsorb metal ions, such as Ca2+、Zn2+、Na+, and endogenous enzymes, which affect the nutrient digestion and absorption. Moreover, mannosan can cause excessive immune response under stress or disease, affect the absorption of glucose by small intestine, interfere carbohydrate metabolism and the secretion of insulin-like growth factor(IGF-1), thus inhibit the growth of animals. Acid β-mannanase is an endomannanase that mainly hydrolyzes galactomannan, glucomannan, galactomannan and mannan, the main chain of which are all 1,4-β-D-pyran mannose, to oligosaccharide which containing 2~10 residues.Challenge Group has been working with the Feed Research Institute of the Chinese Academy of Agricultural Sciences(CAAS) for more t...
