摘要：

Mutant M9-82 from Cellulomonas flavigena PN-120 was obtained by combined treatment of NTG and EMS. Xylanase activity of this mutant strain growing on batch culture, was 33.5 IU/ml, 2.7 times higher than its parent strain. When mutant M9-82 was grown on continuous culture at a dilution rate of 0.05 h(-1), xylanolytic activity increased to 45 IU/ml.
