摘要
在对红曲色素生产菌选育的过程中 ,得到了 9株在麦汁平板上不产红色素的突变株。对稳定性良好的 8株突变株进行固体发酵实验 ,两个样品呈黄色 ,其它呈白色。发酵样品在可见光谱范围内扫描 ,两黄色样品仅在 3 70nm处有一吸收峰 ,其它白色样品无吸收峰。单产黄色素突变株再经液体发酵实验 ,同样单产黄色素 。
mutants which didnt produce red pigmen ts on malt extract agar plate were obtained.The 8 stable mutants were cultured on solid medium.Two samples wer e yellow,the others were white.The extracted samples were scanned in visible len gth.2 yellow samples showed only one absorptive peak at 370nm,the 6 white sample s showed no absorptive peak.The mutants producing only yellow pigments on solid medium were tested in liquid culture.The results indicated their ability to pro duce only yellow pigments were stable.
