| Abstract: | Mucor were isolated by streak platemethod, two Mucor strains were obtained named 1# and 2 e 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 %. |
