PHOTOSYNTHETIC BACTERIA CULTURE

摘要

Photosynthetic bacteria are cultured in a light environment substantially devoid of ultraviolet light in the wavelength region of 340nm or less. If the light environment of suppressed ultraviolet rays is to be obtained from sunlight, a covering member is employed to block out the ultraviolet light. If the light environment is to be obtained from artificial lighting, use is made of a light filter as required. Any photosynthetic bacteria culture medium or organic effluent such as raw sewage can be employed in the culture. Effecting the culture in the foregoing light environment promotes the propagation of fungus bodies and purifies the organic effluent when such effluent is used.
