Xylanase For Improved Bleaching Of Paper Pulps - China

price: contact company for price

Xylan is a major component of wood and non-wood fibres. During cooking

of pulps, the xylan is partially dissolved, modified and re-precipitate

onto the fibre surface. The application of the enzyme, xylanase, to the

cooked pulp removes some of the re-precipitated xylan. This opens up the

pulp matrix, allowing the release of trapped soluble lignin. At the same

time it allows bleaching chemicals to penetrate more effectively. The

overall result is improved bleachability of the pulp with resulting

reduction in usage of bleaching chemicals. AU-PE89 Xylanase is an enzyme

that degrades xylan. AU-PE89 is specific for xylan and does not degrade

cellulose. Xylanases produced by different microorganisms operate

optimally over a range of pH and temperature. AU-PE89 was developed from

a proprietary strain of bacterium for the paper pulp industry. AU-PE89

is particularly suited to the elevated temperatures and alkaline pH of

kraft pulps. The manufacturing process involves growing a specific

proprietary bacterium in bioreactors (fermenters), separating the cells

from the broth, and concentrating the clarified liquid. The product is

prepared as a concentrated liquid or light brown powder.
