Abstract
The oxygen level was reported to play a vital role in the synthesis of pigments and citrinin by M. sp. The objective of this study was to evaluate the relation of pigments and citrinin production and antioxidant activity by adding vitamin c into the mediumn during submerged fermentation of Monascus rubber. The results showed that inoculated vitamin c medium had significantly higher antioxidant activity than uninoculated vitamin c medium at all fermentation time points. The modified M. pilosus fermented product demonstrated a higher pigments and lower citrinin value than the unmodified product. The results of this study showed a new way to increase the yield of Monascus pigments and to decrease the citrinin content by adding vitamin C to the medium.
