PRODUCT DESCRIPTION
This product is produced by submerged fermentation of a traditionally selected Bacillus lentus strain followed by purification, formulation and drying. The product contains variety of activities targeting at hemicellulose, an important part of plant cell wall. The product is used effectively in food, plant extract, feed, textile, pulp & paper, and even petrol oil drilling.
MECHANISM
Hemicellulose comprises heterogenous polysaccharides made up of hexose, pentose and their derivatives, notably xylose and mannose. The multi-component hemicellulase is able to degrade different hemicellulose polymers to produce oligomers and their building blocks. Since hemicellulose makes big part of plant cell wall, and usually presents viscosity problem when released into solution, their degradation leads to disruption of plant cells, liberation of cell inclusions and reduction in viscosity during wet processing of plant materials.

APPLICATION RECOMMENDATION
The recommended dosage is 0.01-1.0%/t DS. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.
SAFE HANDLING PRECAUTIONS
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
