PURPOSE:'To cultivate continuously photosynthetic molds in a culture tank with light rays irradiated by a light emitting tube night and day, by condensing visible light rays such as sunlight, electric light, etc. by a condenser, and introducing the light rays through an optical fiber into the light emitting tube set in the culture tank. CONSTITUTION:Visible light rays such as sunlight, electric light, etc. are condensed by the condenser 6, introduced through the optical fiber 7 into the light emitting tube 3, and photosynthetic molds in the culture tank 1 are cultivated with light rays irradiated by the light emitting tube 3 continuously night and day. Consequently, since sunlight is used in day, electric light in night, the photosynthetic molds can be cultivated with a small amount of electric power. |
