Optimization of Red Pigment Yield from Monscus purpureus Solid State Fermentation (Isolation and Characterization of Monscus purpureus and Optimization of its Red Pigment Production)
Abstract: Natural pigments production is one of the important approaches recently for being natural and having therapeutic properties. Monscus purpureus was isolated from imported red yeast rice, characterized and propagated on local rice as solid state culture. Morphological characteristics which include colonies, ascosporous and conidial stage were used to identify the fungi besides its red pigment production. Red pigment was produced using 10% of seed culture of Monescus purpureus, incubated at …
