摘　　要：对实验室保藏的12株黑曲霉菌株进行了筛选,经紫外、硫酸二乙酯DES诱变最终获得一突变株An08-752.通过培养基优选和发酵条件优化后,其产β-葡聚糖酶酶活力较出发菌株提高了213%,酶活力达到了1.23×105 U/g.A strain An08-752,with high yield of β-glucanase was screened from 12 strains of Aspergillus niger in laboratory by UV and DES. Under the optimum medium and fementation conditions, its β-glucanase activity could reach 1.23×105 U/g,213 % higher then the orginal.
