A mutant, Monascus purpureus G1, was isolated from a wildtype which had been transferred for several times after ultraviolet irradiation. This new strain is extremely dark red in color and also releases more pigment into the yeast extract cultural medium. Unlike strain N11S, another strain of high pigment productivity, G1 is extremely low in antibacterial activity. Sonification for 30 min increased the rate of pigment extraction.
