    Abstract: 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.

    Abstract translation: 提供了一种用于控制干扰纤维漂白和/或在造纸系统中造成其它干扰的有机污染物如木聚糖，沥青或两者的方法。 该方法包括使纤维在其任何漂白之前与含有半纤维素分解酶和有机污染物去除佐剂的组合物接触以释放纤维中的有机污染物。 然后处理的纤维可以被漂白并进一步用于例如制造纸。 本发明还涉及用这些组合物处理的纤维材料制成的处理组合物和纸制品。 还提供了增强底物的酶降解的方法以及用于实现其的制剂和体系。 可以降解或处理各种底物，包括生物质，造纸厂污泥和动物皮。 通过包括一种或多种聚合物表面活性剂可以提高酶降解。
