ABSTRACT:
An apparatus for photosynthesis has a reaction bath in which a plurality of narrow tubular photoradiators are arranged to radiate light therefrom and spaced from each other by a distance which is not more than about 2 mm. Each photoradiator has a cross-section which is cylindrical, equilateral triangular, tetragonal or hexagonal. A baffle plate is disposed below the photoradiators and is formed with a number of apertures therethrough in a predetermined area thereof which may be a radially central area or a generally annular peripheral area. CO.sub.2 -containing air is fed into the reaction bath through the apertures in the baffle plate to circulate along a predetermined path inside the reaction bath due to the remaining non-apertured part of the baffle plate. The function of the baffle plate may be performed by plugging which blocks the passage of the air through the spacings between the lower ends of the adjacent photoradiators in the predetermined area. The circulation of the air may be caused more positively along a variable path by a rotor which is positioned below the photoradiators and rotatable by ejecting the air while supplying it to the interior of the reaction bath. The rotor is cushioned and supported by the air ejected therefrom during operation.
