CULTURE APPARATUS FOR MICROALGAE

PROBLEM TO BE SOLVED: To provide a culture apparatus for microalgae which can culture microalgae which have been cultured under an aerobic condition under a sufficient anaerobic condition while culturing microalgae under the aerobic condition.SOLUTION: A culture apparatus for microalgae includes: a tank body for holding a mixture of microalgae and a culture solution; air diffusion parts arranged in an internal space of the tank body for supplying oxygen gas to the mixture; and a partition plate for vertically separating the internal space of the tank body on the lower side of the air diffusion parts. Inside the tank body, an opening is formed through which a space on the upper side of the partition plate communicates with a space on the lower side of the partition plate.
