摘　　要：以里氏木霉 (Trichodermareesei)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 ,可大幅度提高木聚糖酶活力。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 4 5%。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.
