The influence of salicylic acid (SA) and methyl jasmonate (MeJa) on the biomass and pigments production in Monascus purpureus was investigated. With 100 μmol/L SA- and 10 μmol/L MeJa-treated cultures, the maximum biomass were 4.70 and 4.33 g/L and significantly higher than the control, respectively. Supplemented with 10 μmol/L SA or MeJa, extracellular yellow, orange and red pigments increased, respectively, compared to the control. Supplemented with 10 μmol/L SA or 30 μmol/L MeJa, intracellular yellow, orange and red pigment production increased mostly compared to the control. AP activity was significant induction with SA and MeJa supplementation and the most significant at the 8^th day of induction. These results indicate that proper concentration SA or MeJa enhance the biomass and pigment production in Monascus purpureus. Salicylic acid improved biomass and pigment production significantly more than MeJa.

水杨酸和茉莉酸甲酯对红曲霉生长和色素产生的影响。

研究了水杨酸（SA）和茉莉酸甲酯（MeJa）对红曲菌生物量和色素生成的影响。用100μmol/ L的SA和10μmol/ L的MeJa处理的培养物，最大生物量分别为4.70和4.33 g / L，分别显着高于对照。补充10μmol/ L SA或MeJa，与对照组相比，细胞外黄色，橙色和红色色素分别增加。补充了10μmol/ L的SA或30μmol/ L的MeJa，与对照组相比，细胞内黄色，橙色和红色色素的产量增加最多。AP活性显著诱导SA和补充的MeJa，并在8最显著^日上岗日。这些结果表明，适当浓度的SA或MeJa可以提高红曲菌的生物量和色素的产生。水杨酸比MeJa显着提高了生物量和色素产量。
