<P>PROBLEM TO BE SOLVED: To provide a method and apparatus of a vertically arranged transparent water tank for culturing to proliferate photosynthetic microorganisms healthfully in which animalcules such as water flea, rotifer and the like easily preying on photosynthetic microorganisms are inhibited to invade and proliferate. <P>SOLUTION: The method for culturing photosynthetic microorganisms uses a culture apparatus equipped with a transparent water tank 1 made of light-transmissible material and a floating lid 2 installed in the water tank 1 for proliferating photosynthetic microorganisms by irradiating the contained photosynthetic microorganism suspension with sunlight. (A), Under a light condition, the photosynthetic microorganism suspension is led above the floating lid 2 to be irradiated with light, and (B), under a dark condition, the photosynthetic microorganism suspension is not led above the floating lid 2 so that the animalcules, such as water flea, rotifer and the like preying on photosynthetic microorganisms under an anaerobic condition, are inhibited to proliferate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
