主要研究了乳酸和乳酸钠对红曲霉突变菌株代谢合成红曲色素和橘霉素的影响.实验结果表明,添加一定量的乳酸和乳酸钠都有利于红曲色素(包括黄色素和红色素)的合成代谢,有利于黄色素合成代谢的最适乳酸或乳酸钠添加量在0.01～0.05 mL/30mL之间,而有利于红色素合成代谢的最适乳酸或乳酸钠添加量在0.05～0.1mL/30mL之间,红曲霉突变菌株利用乳酸或乳酸根作为其生长的底物和红曲色素合成代谢的底物.乳酸或乳酸盐本身对红曲霉突变菌株合成代谢橘霉素没直接的影响,其形成的发酵pH环境直接影响了橘霉素的合成代谢.

The effect of lactic acid and sodium lactic acid on Monascus pigments and citrinin production by Monascus anka mutant MYM2 were researched.The results indicated that lactic acid and sodium lactic acid were beneficial for Monascus pigments（ including red and yellow pigments）production by Monascus anka mutant, the best addition concentration of lactic acid or sodium lactic acid for yellow pigments production was between 0.01mL and 0.05mL per 30mL cultures, but for red pigments production, it was between 0.05mL and 0.1mL per 30mL cultures.
