Abstract

A culturing apparatus for photosynthesis microorganism provided by the present invention comprises a outer vessel, inner vessel, culture solution circulating portion and a heat transfer medium feeding portion. Culture solution containing photosynthesis microorganism is put into the outer vessel which is transparent and configured like a cylinder extending in a predetermined axis-direction. The inner vessel is disposed in the outer vessel, being configured like a cylinder extending in the above axis-direction. The culture solution circulating portion draws culture solution from one side along the axis-direction in the outer vessel, supplying that to the other side of the axis-direction. The heat transfer medium feeding portion supplies heat transfer medium into the inner vessel.

Claims

1. A culturing apparatus for photosynthesis microorganism comprising:

a transparent outer vessel which accommodates culture solution containing photosynthesis microorganism and is configured like a cylinder extending in a predetermined axis-direction;

an inner vessel which is disposed within said outer vessel and configured like a cylinder extending in said axis-direction;

a culture solution circulating portion which draws said culture solution from one side along said axis-direction in the outer vessel and supplies the drawn culture solution to the other side along said axis-direction in the outer vessel; and

a heat transfer medium feeding portion which supplies heat transfer medium into said inner vessel.

2. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said outer vessel and said inner vessel are arranged coaxially.

3. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein both said outer vessel and said inner vessel are cylinders.

4. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said inner vessel is made of a metal material or a glass material.

5. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said inner vessel is made of a resin material.

6. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said culture solution circulating portion is provided with a transparent and cylindrical tube through which said culture solution flows.

7. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said axis-direction is a vertical direction.

8. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said culture solution circulating portion is provided with a transparent tube, in which said culture solution flows, and a first nozzle,

said transparent tube being configured like a cylinder extending in a vertical direction, and

said first nozzle being disposed at a lower part of said transparent tube and supplying a gas into said transparent tube.

9. A culturing apparatus for photosynthesis microorganism according to claim 7, wherein a second nozzle supplying a gas is disposed at a bottom part of said outer vessel.

10. A culturing apparatus for photosynthesis microorganism according to claim 1, wherein said heat transfer medium is heating medium or cooling medium.

11. A method of culturing photosynthesis microorganism, wherein said photosynthesis microorganism is cultured by the use of a culturing apparatus according to claim 1.
