研究了好食脉孢菌固体发酵生产木聚糖酶的条件，以提高其产量。通过单因素及Plackett‐Burman设计法，初步选出生产木聚糖酶适合的培养条件和无机盐种类。结果表明：培养基主要物料是豆饼粉、玉米皮，比例为4∶1，无机盐为0．3％硫酸铜与0．6％氯化钙，发酵时间为60h，浸提时间为4h，在此优化条件下，木聚糖酶活力可达577 U／m l。

The solid state fermentation conditions of xylanase production by Neurospora sitophila was studied ,in order to improve the yield .Through single factors and Plackett‐Burman design method ,the optimum culture conditions and inorganic salt types were selected .The results showed that the suitable culture medium was composed of soybean powder and corn bran with the ratio of 4∶1 ;inorganic salt was copper sulfate and calcium chloride with concentration of 0 .3% and 0 .6% ,respec‐tively ;fermentation time was 60 h and extraction time was 2 h . Under the conditions ,the activity of xylanase reached 577 U/m l .
