To mitigate the effects of carbon dioxide discharged from a boiler in a power plant, CO2 fixation by microalgae photosynthesis was studied. For the algae cultivation, actual flue gas from a boiler was used in two sets of small-sized raceway-type cultivators installed at Tohoku Electric Power Company's Shin-Sendai power station. UsingNannochloropsis sp. NANNP-2 andPhaeodactylum sp. PHAEO-2 strains from the SERI collection, the microalgae were cultured semicontinuously and harvested periodically. From the results of the field test, the productivity of both strains using direct flue gas was almost on a par with that of bombed CO2 gas. Therefore, it was clarified that the direct blowing of flue gas into the cultivator did not adversely affect algal growth.
