摘要
以枯草芽孢杆菌(Bacillussubtilis)和蜡状芽孢杆菌(Bacilluscereus)为出发菌株,采用紫外诱变的方法获得了2株木聚糖酶高产菌株,酶活分别是原来的17·50倍和17·20倍。选取酶活最高的菌株进行发酵条件的研究。
Use Bacillus subtilis and Bacillus cereus as initial strain, we can get two strains of high enzymic activity for xylanase, enzymic activity is 17.50 and 17. 20 times as before respectly. Study the ferment condition of the highest enzymic activity strain.
