| Abstract: | 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. |
