Cellulase

Description

Cellulase is extracted from choiceness strains by microbial fermentation technology, and advanced post-processing techniques. As a kind of multi-component compound enzyme,  cellulase contains several kinds of incision enzyme with synergistic effect which can catalyze the hydrolysis of cellulose and generate oligosaccharide and cellose which finally decomposed into glucose.

 

Cellulose is widely exist in botanical feedstuff with high molecular weight. It is exist in cell wall as crystal form, and insoluble in water.The steric hindrance to nutrients such as wrapping, winding, blocking is the main reason of its anti-nutrient effect.

Functions

1. Effectively degrade cellulose, destroy the cell wall, remove the protection to inside nutrients and increase digestibility and absorptivity.

2. Reduce the physical injury of cellulose to animal intestine, reduce intestinal disease.

3. Improve the utilization of unconventional feed, reduce feed cost.

4. Regulate intestinal microflora, improve immune functions.


Features

1. pH range: valid pH range is pH2.5-7.0, optimal pH is 4.5. Play a positive role in animal digestive tract.

2. Temperature range: valid temperature range is 30-80℃, optimal temperature is 50℃.

3. Rich zymogram, the combination of endo-enzyme and exo-enzyme has a good synergistic effect, higher efficiency, better degradation 

of cellulose and reducing anti-nutrition effect.
