Comparison of lovastatin, citrinin and pigment production of different Monascus purpureus strains grown on rice and millet.

ABSTRACT: Six Monascus purpureus (red mould) strains were cultivated on brown rice and millet as substrates. They underwent strain selection for high lovastatin and pigment production, and low citrinin mycotoxin production, with particular reference to potential for millet as substrate. For most of these strains, substrate dry matter loss was 54-60% on rice and 46-48% on millet, although the 'MOPU GS1' strain showed 18% and 17% dry matter loss, respectively. 'MOPU GS1' was also the only strain with detectable levels of lovastatin (1.3 and 1.6 mg lovastatin/g substrate dry weight [dw], respectively) and citrinin under the limit of detection. In the other strains, citrinin varied from 0.3 to 18.2 mg/g substrate dw. Among the six strains, 'EBY3' provided high pigment production when grown on ric
