  • 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.
