| 摘 要： | 通过采用紫外线、60Co-γ射线对紫红曲霉(Monascus purpureus Went)进行复合诱变,获得一株突变株,其发酵色价达到48.4U/mL,是出发株的3.67倍。该突变株色价提高幅度明显,传代稳定性良好,可作为生产红曲红色素的优良菌株。

| Abstract: | Monascus purpureus AS3.972 was treated with both ultraviolet and ~(60)Co gamma-ray, and an optimal mutated strain with pigment value of 48.4 U/mL was obtained. The mutant had a pigment value 3.67 times higher than the original strain. This mutant had an obvious higher pigment value, a stable genetic property and is hence a fine strain for producing high-quality monascus pigment. |
