[Accumulation of carotenoid in Colletotrichum gloeosporioides induced by blue light].
Blue light induced carotenoid accumulation in filamentous fungus- Colletotrichum gloeosporioides. The pigment particles were observed in the fungal mycelium by microscope after blue light irradiation. The pigmentation was not found in the fungal mycelium either cultured under dark condition or cultured in red light. The accumulation of the carotenoid was regulated by blue light intensity. When C. gloeosporioides was incubated in blue light of 6.5micromol x m(-2) x s(-1) under 28degreesC, carotenoid content increased with the irradiation time and reached to a peak of 71.8microg/g FW at 5d. The treatment of dark pre-culture of C. gloeosporioides also had effect on the production of the pigment induced by blue light.
