摘　　要：以大曲丢糟和麦麸为主要原料生产饲用木聚糖酶。结果表明,最适产酶培养基组分为:干酒糟40%、麦麸50%、菜枯10%、(NH4)2HPO40.25%、Tween800.1%,30℃培养2～3d,产酶最高达13265.8IU/g,具有较好的应用前景。Daqu spent grains and wheat bran were used as main raw materials to produce feed xylanase. The results showed that the best technical parameters were as follows： 40 % dry spent grains, 50 % wheat bran, 10 % dregs of rapeseeds after being extracted, 0.25 % （NH4）2HPO4, 0.1 % Tween80, and 2～3 d culture at 30 ℃. The maximum enzyme yield reached 13265.8 IU/g. The method had promising application foreground.
