<p>Provided is a stirring machine for photosynthesis by which light required for a photosynthetic reaction can uniformly irradiate a liquid culture medium and disperse therein without depending on sunlight, aquatic organisms can be cultured while avoiding damages on the aquatic organisms' bodies being cultured caused by the stirring and preventing the adhesion of the aquatic organisms to the container wall, and the life of a light source can be extended. A stirring machine comprising: a hollow shaft (2), which also serves as a carbon dioxide gas supply pipe (1), constituting a rotational shaft; a plurality of cylindrical or conical transparent stirring blades (19) being radially attached, at regular intervals and at irregular heights, to the hollow shaft; one or more light-emitting diodes (21) with three different kinds of light qualities including blue, red and far-red, being provided in the vicinity of each of the attachment sites; a supply pipe for supplying a solution to be supplied, which comprises a nutrient salt solution optionally together with an alkali solution for neutralizing carbon dioxide, being provided at the bottom of the hollow shaft; a damping mechanism against an upward thrust force, which is generated by the supply of carbon dioxide gas and said solution to be supplied, being fixed to the outer side face in the upper part of the hollow shaft; and a slidable mechanism for supplying electrical power to the light-emitting diodes being attached around the hollow shaft.</p> |
