To Monascus spp., light is not the required factor for its growth. But Monascus spp. has the capacity to sense and respond to light. This paper investigated the effects of blue light on growth and the changes of citrinin yield in Monascus 15. Our results demonstrated blue light was a stimulating signal for citrinin formation. Under the blue light illumination, the biomass of Monascus 15 was inhibited, but the citrinin yield increased when comparing with no light culture condition. Spores statistical results revealed that the blue light also influences the development of mycelium and spore formation.
