Following our investigations on citrinin production by Monascus ruber in a chemically defined medium, the kinetic behaviour of this toxin in the fermenter was studied with relation to production of pigments, biomass and nutrient consumption. Showing a secondary metabolite pattern, citrinin was produced when dμ/dt and dQs/dt were ≤ 0, while a high specific production rate of pigments occurred when dμ/dt and dQs/dt were 〉 0. No trophophase-idiophase transition was detected during the cuitivation, and the behaviour of pigment production was similar to that of a primary metabolite.
