Mannanase Enzymes For Animal Feed Additive Nutrizyme MNA
Introduction
The β-mannase [EC 3.2.1.78] is a highly concentrated thermostable β-mannase 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, which causes the viscosity of chyme and retards the digestion and absorption of nutrients. β-Mannase belongs to the family of hemicellulose hydrolase that splits β-1,4-glycosidic bond in β-mannan, galactomannan, and glucomannan, producing mannose oligosaccharides and mannose. Meanwhile, it removes the anti-nutritional effects of mannan and reduces chyme viscosity.
Specifications
| Items | Standard |
| Appearance | Powder |
| Colour* | Light yellow |
| Odour | Slight fermentation odour |
| Activity** | 3,000 u/g~25,000 u/g |
*Color can vary from batch to batch. Color intensity is not an indication of enzyme activity. **1 unit of β-mannanase equals to the amount of enzyme which hydrolyzes 3mg/ml mannan solution to get 1μmol reducing sugar (mannose basis) in 1min (u), at 37℃ and pH 5.5.

Functions & Benefits
As a feed additive, it can improve feed utilization and animal growth performance.
- Degrade mannan in feed, eliminate anti-nutritional factors of mannan, and increase the feed digestibility.
- Disrupt plant cell wall, release the nutrients, and increase nutrient digestion and utilization.
- Reduce viscosity of chyme in the digestive tract, promote nutrient digestion and absorption in the intestine.
- The mannose oligosaccharides produced improve intestinal microflora and regulate the immune system.
- Enhance animal performance and reduce the cost of feed production.
- Reduce the nutrients in the animal excrement, improve the animal house environmental sanitation.
