| Abstract: | A yeast strain rich in protein and nucleic acid was selected by neans of anameliorational induced nutational methods in combination with ultraviolet radion and5-F-uracil, and the essential nutration factors and cultural conditions were determined bythe methods of orthogonal designs. The average conten of nucleic acid and protein in theselected strain is 14.75% and 63.67% on a dry basis of cell in flask culture.Thefermentational test results in 1.5 L fermentor proved that the mutant has a good gentic sta-bility. |
