| Abstract: | Mucor were isolated by streak platemethod,two Mucor strains were obtained named 1# and 2#.The protease activity of 1# and 2# were 6 565.209 U/g and 9 146.015 U/g respectively.Mutate breeding was made to enhance the producing capability of the strain.U1# compared to 1#,the protease activity increased 48.58%,U2# compared to 2#,the protease activity increased 54.45%. |
