Abstract

The xylanase production by Cochliobolus sativus strain Cs6 was improved under solid state fermentation (SSF). High xylanase activity (1079 U/g) was obtained when wheat straw was used after 8 days of incubation. Combinations of sodium nitrate with peptone or yeast extract resulted in an increased xylanase production (1543 and 1483 U/g, respectively). The Cs6 strain grown in SSF in a simple medium, proved to be a promising microorganism for xylanase production.

摘要

木聚糖酶由禾旋孢腔菌菌株 Cs6 在固态发酵（SSF）下生产。当使用小麦秸秆作为发酵基质并在 8 天后培养时，获得了最高的木聚糖酶活性（1079 U/g）。硝酸钠与蛋白胨或酵母提取物的组合导致木聚糖酶产量增加（分别为 1543 和 1483 U/g）。Cs6 菌株在简单培养基中进行 SSF 培养，证明是一种有前途的生产木聚糖酶的微生物。
