Nutrizyme^® β-mannanase [EC 3.2.1.78] is a highly concentrated thermostableβ-mannanase preparation produced by submerged fermentation of Bacillus lentus followed by purification and formulation.

Mannan widely exists in plant materials of feed, especially in palm kernel meal, soybean meal, and sesame meal, etc., which causes the viscosity of chyme and retard the digestion and absorption of nutrients and so on. β-Mannanase belongs to the family of hemicellulose hydrolase that splits β-1,4-glycosidic bond in β-mannan, galactomannan and gluco-mannan producing mannose oligosaccharides and mannose. Meanwhile, it removes anti-nutritional effects of mannan and reduces chyme viscosity.
