Abstract

Abstract: A high yield and stable succinic producing strain S-57 was obtained from the mutation of mucor S-1 treated with ultraviolet ray and nitrosoguanidine (NTG). After the strain S-57 was treated with He-Ne laser, a strain SH-24 was selected. The concentration of succinic acid is 21.25 mg/ml in the fermentation broth of the same conditions of fermentation or that is 343 times the strain before mutagenesis.

Key words: succinic acid, sltraviolet ray, nitrosoguanidine, laser, mutation
