PROBLEM TO BE SOLVED: To provide a culture system capable of efficiently separating photosynthetic microorganisms from culture solution.SOLUTION: A culture system 100 is constituted such that a plurality of culture tanks 10a, 10b, 103c, 10d, 10e (10) are connected in multiple stages, culture solution M in each culture tank 10 out of the culture tanks 10a, 10b, 103c, 10d, 10e (10) circulates to the culture tanks 10 in lower stages, and the depth of the culture solution M in each culture tank 10 out of the plurality of culture tanks 10a, 10b, 103c, 10d, 10e is made gradually shallower toward downstream in a circulating direction of the culture solution M. |
