    • The present invention concerns a method for enzymatic treatment of lignocellulosic materials, in particular cellulose pulps. According to a method of this kind, the material is contacted with an enzyme preparation having hemicellulase, cellulase and/or ligninase activity in order to hydrolyse the hemicelluloses, cellulose and/or lignin thereof. According to the invention, the counter-ions of the carboxylic groups of the lignocellulosic material are modified before the enzymatic treatment in order to render the material more suitable for enzymatic treatment. By changing the nature of the counter-ions of the carboxylic acids or by changing their degree or dissociation, it is possible to adjust the enzymatic action on the lignocellulosic material of the enzymes employed. At the same time, it is possible to select which part of the fibres is subjected to the enzymatic action.
    • 本发明涉及用于酶处理木质纤维素材料,特别是纤维素纸浆的方法。 根据这种方法,材料与具有半纤维素酶,纤维素酶和/或木质素酶活性的酶制剂接触,以水解其半纤维素,纤维素和/或木质素。 根据本发明,在酶处理之前修饰木质纤维素材料的羧基的抗衡离子,以使材料更适合于酶处理。 通过改变羧酸的反离子的性质或通过改变它们的程度或解离,可以调节所用酶的木质纤维素材料的酶作用。 同时,可以选择纤维的哪一部分进行酶促作用。
