Abstract: Various mutating methods including ultraviolet, 60Co, DES and complex of them were applied to mutate the soy saucefermentation strain-Aspergillus Oryzae. The strains by various mutating methods were screened respectively according to theprotease activity. The effects of mutating methods on the enzyme system distribution were discussed. At the same time thesensitivity of with respect temperature and the moisture were studied.

Key words: Aspergillus Oryzae, mutating, screening
