Mutant strain of Aspergillus niger by electron beam was selected to be the object.To explore the enzymatic characteristics of glucoamylase produced by mutant strain of Aspergillus niger by the optimum pH test,the optimum temperature test,thermal stability test,acid-base stability test and the expetiment on the offect of metal ions on the activity of glucoamyase.The results showed that glucoamylase was produce at 63℃and the highest enzyme activity was 26%higher than the original strain.8.4 k U/mL enzyme acti...
