摘要
使用EMS对出发菌株CⅠ进行诱变,通过蛋氨酸抗性平板,筛选出了一株产硫化氢低、产谷胱甘肽高的突变株M6;M6的基本发酵性能与出发菌株CⅠ相差不大,但GSH的生成量比CⅠ提高了47.7%,H2S的生成量比出发菌株CⅠ降低了36.3%。
A fine mutant M6 which produced low H2S and high glutathione GSH was obtained through anti-methionine medium after the mutation of parent strain C I by the use of EMS. There was no evident difference in basic fermentation performance between M6 and parent strain C I. However, the yield of GSH by M6 increased by 47.7 % than that by C I, and the yield of H2S decreased by 36.3 %.
