    • A novel enzyme-active fibrous material is proposed comprising fibers of a rtially aminoacetalized polyvinyl alcohol as the support and an enzyme adsorbed and bonded thereto such as glucose isomerase, invertase, urease and the like. The enzyme-active fibrous material of the invention is readily prepared by dipping fibers of the partially aminoacetalized polyvinyl alcohol in an aqueous solution of the desired enzyme. The enzymatic activity and the physical properties of the fibers are remarkably improved by the use of extra-fine fibers prepared with composite fibers of a partially aminoacetalized polyvinyl alcohol and a polyethyleneoxide subjected to selective leaching away of the latter component or by the use of so-called sheath-and-core type or side-by-side type composite fibers of which one of the components is a partially aminoacetalized polyvinyl alcohol.The enzyme-active fibrous materials of the invention can be used in various industrial processes utilizing enzymatic reactions very conveniently and with high efficiency.
    • 提出了一种新型的酶活性纤维材料,其包含作为载体的部分氨基缩醛化聚乙烯醇纤维和与其结合的酶,如葡萄糖异构酶,转化酶,脲酶等。 本发明的酶活性纤维材料通过将部分氨基缩醛化的聚乙烯醇的纤维浸渍在所需酶的水溶液中而容易地制备。 通过使用由部分氨基缩醛化的聚乙烯醇和经过选择性浸出后者的聚环氧乙烷的复合纤维制备的超细纤维或通过使用所谓的纤维素,可以显着提高纤维的酶活性和物理性能。 称为皮芯型或并列型复合纤维,其中一种组分是部分氨基缩醛化的聚乙烯醇。 本发明的酶活性纤维材料可以非常方便和高效地利用酶反应的各种工业过程中使用。
