纤维素和木聚糖复合诱导合成木聚糖酶的研究

以里氏木霉（Rrichoderma reesei)为产酶菌，分别对纤维素、纤维素和木聚糖诱导产酶的功能进行了研究。研究发现，纤维素具有诱导木聚糖酶合成的功能；纤维素和木聚糖混合对木聚糖酶合成具有促进作用，可大幅度提高木聚酶活力。与纯木聚糖（5g/L)产酶相比，纯木聚糖（4g/L)和纸浆（1g/L)混合产酶木聚糖酶活可以提高45％。研究成果为采用富含木聚糖的植物纤维料作碳源制备木聚糖酶提供了理论依据。

STUDY ON THE PRODUCTION OF XYLANASES CO INDUCED BY CELLULOSE XYLAN

This paper deals with the inducing function of cellulose and cellulose xylan mixture on xylanases production with Trichoderma reesei . It was found that xylanase could be induced by cellulose, whereas cellulose xylan exhibited a kind of co inducing function to xylanases, which could greatly improve xylanase activity. Compared to pure xylan(5 g/L) xylanase activity could be increased by 45% by using xylan (4 g/L) pulp(1 g/L)mixture as carbon source. This result provides the theoretical basis for xylanase production with plant fibre raw materials rich in xylan as carbon source.
