摘要
从土壤中分离到4株木聚糖酶高产菌——A_(34)、B_1、C_(13)和D_(15)。它们在2%燕麦木聚糖液体培养基中的酶活(u/ml)依次为378、402、291和344;在麦麸固体培养基中的酶活(u/g)依次为2940、3139、2156和2696。经鉴定,A_(34)为黑曲霉(Aspergillus niger),B_1为木霉菌(Ticho-derma sp.),C_(13)为土曲霉(Asp. terreus),D_(15)为顶青霉(Penicillum corylophilum)。
The four high-producers of xylanases, A_(34), B_1, C_(13), D_(15), have been isolatedfrom soil. The extracellular xylanases acitivites of these strains in aqueous medium can-taining 2% Oat-spelt xylan reaches 375, 402, 291, 344(u/ml), respectively. on wheatbran solid fermentation, the activitties per gram of dry medium were 2940μ/g for A_(34),3189μ/g for B_1, 2156μ/g for C_(13) and 2696μ/g for D_(15). The four strains were identifiedas Aspergillus niger, Trichoderma sp. , Aspergillus terreus, Penicillum corylophilumrespectively.
