The aim of this research is to study the kinetic characterization of red pigment production throughout the solid-state fermentation. Nutritional factors (nitrogen and carbon sources) and environmental factors (moisture content, pH, inoculum size) on red pigment were investigated. The results indicated that the highest maximum growth rate (µmaxx), mean cell (Pcells), conversion of substrate into biomass (Yx/S ), conversion of substrate into red pigments (Yp/S) and conversion biomass into red pigments (Yp/X) were obtained at day 5 with 2% peptone. Overall, the red pigment produced by Monascus purpureus FTC 5357 highest at 2% peptone, 5g of oil palm fronds, pH 6, 50% of moisture content, at 30°C and 108 spores ml-1 inoculum size. These findings are important to be used for optimizing the red pigment production.
