摘要:

应用 10keV的N+离子注入,对产红色素红曲菌进行了诱变选育。在确定最佳注入剂量后,经过两轮离子注入诱变筛选,选育出 1株高产突变株,红色素色价提高 3 8.1 %,且色调适宜。经传代培养,其高产性状能稳定遗传。对该菌株的发酵特性也进行了研究。

Abstract:

The red pigment producing strain Monascus was mutagenized by 10 keV N+ ion implantation. After the optimal mutation dose was determined, one high yielding strain was bred through two rounds of mutagensis.The red pigment yield increases 38.1 %, and its tone is good.The ferment characteristic of the strain was also studied

Key words: ion implantation, Monascus, red pigment, mutation, breeding
