Abstract: In an attempt to search for strains for high productivity of Monacolin K, pigment and low productivity of citrinin,16 isolates of Monascus sp. were tested, and of those strains HS-9 of Monascus purpureus was selected as an original isolate forartificially induced mutation. The citrinin, Monacolin K and color value of the mutant HS-9-125 were 0.65 mg/kg, 4.855 mg/g and3580 U/g, respectively.

Key words: Monascus sp, citrinin, mutation
