Abstract: 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 8th 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.
