PURPOSE:To obtain a bioreactor capable of converting CO2 into O2 by photosynthesis by passing fine algae and culture medium into a vessel in which a gas- exchangeable hollow fiber membrane and optical fiber having high light permeable property are integrated, feeding CO2 from the side wall and irradiating the optical fiber with light from light source. CONSTITUTION:In a bioreactor capable of converting CO2 into O2 utilizing photosynthesis of fine algae, the fine algae and culture medium are passed through a vessel in which a number of hollow yarn membranes 6 having high light permeability and gas-exchangeable and a number of optical fibers 7 closely arranged to the vicinity thereof are integrated and CO2 riched gas inlet 3 communication a gas chamber of a vessel is provided behind the flow direction of side wall of the vessel and O2 riched gas inlet 4 communicating with the gas chamber is provided on the upper stream of flow direction of side wall of the vessel and a feed port 1 for feeding fine algae and culture liquid into a hollow yarn membrane 6 is provided on one end of the vessel and outlet 2 is provided on other end of vessel and the fine algae is irradiated with light from light source 8. Thereby CO2 is converted to O2 utilizing photosynthesis. |
