Abstract
The fungus Monascus produces several secondary metabolites of different
pigment hues. These pigments have shown various biological activities. In
this study, Monascus purpureus pigment extracts were tested (in vitro) against
Penicillium expansum MTCC 4900, Rhizopus stolinfer MTCC 10595, and
Aspergillus niger MTCC 8652 for antifungal activity. The UV–visible spectrum of
M. purpureus fermented rice extracts showed lmax at 395, 425, and 500 nm.
This indicated the solubility of yellow, orange, and red pigments in polar-based
solvent extraction. The M. purpureus pigment extracts inhibited the radial growth
and conidial germination of the test fungi. The fungi treated with pigment extract
stained with DiBAC (a vital stain) emitted green fluorescence under a fluorescent
microscope. These results indicated that the pigment extracts have a
