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 a variety of activities targeting hemicellulose, an important part of the plant cell wall. The product is used effectively in food, plant extract, feed, textile, pulp & paper, and even petrol oil drilling.
Function and Application
Fruit and vegetable: Used together with pectinase and cellulase for juice yield improvement and juice clarification.
Coffee: Increases extraction yield of coffee.
Feed: Improves biological value and utilization of feed by removing anti-nutritional components in feed.
Edible oil extraction: Increases oil yield by enzymatic pretreatment.
Petrol oil drilling: Used as an enzymatic breaker to degrade biological mannan containing thickening agents like guar gum, xanthan gum, konjac gum, etc., reducing environmental pollution by fracturing liquid.
Pulp & Paper: Bleaches pulp by degrading hemicellulose and reduces the use of chemicals.
Mechanism
Hemicellulose comprises heterogeneous 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 up a big part of the plant cell wall and usually presents viscosity problems when released into a solution, their degradation leads to the disruption of plant cells, liberation of cell inclusions, and reduction in viscosity during wet processing of plant materials.
