Habio Alkaline Xylanase for Paper Industry

Introduction

Mechanism:

Xylan is a kind of polysaccharide, which widely exists in plant. As an important component of cell wall and plant structure organization, as one of the important part of hemicellulose, xylan always combined with cellulose, xylogen and the others in forms of compounds existing in plant. In papermaking industry the interspaces of pulp matrix are always blocked by xylan and xylogen, thus lower the quality of paper and pulp. Also it reduces bleaching efficiency, lowers paper whiteness , always causes bleach overuse and brings someenvironmental issues such as paper strength and bleaching waste water exceed standard.

Habio Alkaline Xylanase is developed by Habio for specially degrading xylan as industrial enzyme with molecular biology, microbial fermentation technology and other modern biological technology. It comes from single strain microbial fermentation, using Asia's leading advanced post-processing techniques, with both endo and exo-function (both EC 3.2.1.8 and EC 3.2.1.92 function), effectively degrades xylan in pulp, helps separate pulp cellulose from xylogen, xylan and other impurities. Thus highly improving pulp quality and whiteness, reducing cost of pulp treatment and waste water treatment.

Product Features:

1, Specially degrading xylan without cellulase, won’t reduce pulp fiber quality or paper strenth.

2, High stability, with high activity at PH 5.5-10.5 and a broad range of temperature from 40°C to 70°C. It fits well and easy to be integrated into most present production lines of pulp production process.

3, Reducing bleach usage 15-60%, at the same time improve speed of pulp filtration

5-10% and also pulp yield. Thus reduce production cost and increace production efficiency.

4, Improving fiber strenth and paper quality in addition to effectively increacing pulp whiteness with the same bleach and decreacing bleach usage.

5, Lowering COD and BOD in waste water, decreacing time and cost of waste water treatment.
