紫外线诱变黑曲霉提高产酶活力的研究

摘要

[Objective] The research aimed to breed the high-yield production strain of cellulase.[Method] Aspergillus niger was used as the starting strain,and a high-yield production strain of cellulase was selected after UV mutation treatment.[Result] Under the suitable condition,the strain 2（15） with the highest CMC production capacity was selected,which nearly increased 50% than that of the starting strain.[Conclusion] The research provided the foundation for its appliation in the feed production in the future.%[目的]选育高产纤维素酶生产菌。[方法]以一株黑曲霉（Aspergillus niger）为出发菌株,经过紫外线（UV）诱变处理,选育出一株纤维素酶高产菌株生产菌。[结果]在适宜的条件下,选育得到的菌株2（15）产CMC活力最强,与出发菌株相比提高了近50%。[结论]今后应用于饲料生产中提供基础。
