METHOD AND COMPOSITION FOR ENZYMATIC TREATMENT OF FIBER FOR PAPERMAKING, AND PAPER PRODUCTS MADE THEREWITH
A method is provided for controlling organic contaminants, such as xylans, pitch or both, that interfere with bleaching of fibers and/or cause other interference(s) in papermaking systems. The method includes contacting fibers before any bleaching thereof with a composition which contains a hemicell...

| description | A method is provided for controlling organic contaminants, such as xylans, pitch or both, that interfere with bleaching of fibers and/or cause other interference(s) in papermaking systems. The method includes contacting fibers before any bleaching thereof with a composition which contains a hemicellulolytic enzyme and an organic contaminant removal adjuvant to liberate the organic contaminants from the fibers. The treated fibers can then be bleached and further used, for example, in making paper. The present invention also relates to the treatment compositions and to paper products made with fiber materials treated with these compositions. A method of enhancing enzymatic degradation of a substrate as well as formulations and systems for achieving the same are also provided. Various substrates can be degraded or otherwise processed, including biomass, paper mill sludge, and animal hides. Enzymatic degradation can be enhanced by including one or more polymeric surfactants.
Une méthode est fournie servant à contrôler les contaminants enzymatiques, comme les xylanes, le brai ou les deux, qui interfèrent avec le blanchissage de fibres ou causent dautres interférences dans les systèmes de fabrication du papier. La méthode comprend la mise en contact des fibres avant leur blanchissage au moyen dune composition qui contient un enzyme hémicellulolytique et dun adjuvant denlèvement de contaminant organique pour libérer les contaminants organiques des fibres. Les fibres traitées peuvent alors être blanchies et ensuite utilisées, par exemple, pour la fabrication du papier. La présente invention porte également sur les compositions de traitement et les produits de papier faits du matériau de fibre traité au moyen de ces compositions. Une méthode damélioration de la dégradation enzymatique dun substrat ainsi que des formules et des systèmes de réalisation associée sont également divulgués. Divers substrats peuvent être dégradés ou autrement traités, y compris la biomasse, la boue de papetière et les peaux danimaux. La dégradation enzymatique peut être améliorée en incluant un ou plusieurs surfactants polymériques. |
