摘要
泡盛曲霉(Asp.awamori)是曲霉属中具有重要应用前景的菌株之一,利用该菌可以制备多种酶制剂。本实验对泡盛曲霉AS2437菌株酶系组成进行了分析。用不同原料进行液体发酵,麸皮产酶水平最高、豆皮次之,米糠最低;麸皮培养基发酵液中木聚糖酶、纤维素酶和淀粉酶的酶活力分别达到25.35、0.64、29.97U/mL,粗蛋白含量169.00μg/mL;在培养基中添加葡萄糖,三种酶的产量均有不同程度的降低。
The enzyme system of Asp. awamori AS 2437 was analyzed.This strain produced highest activities with bran as only carbon source,25.35U/mL of xylanase,0.64U/mL of cellulase and 29.97U/mL of a-amylase per milliliter of broth was obtained,the crude protein was 169.00μg/mL. Addition of 1% glucose to the media inhibited the production of these enzymes.
