By the way, the intermediate products of this continuous reaction It is known that NADPH inhibits the dark reaction if it is formed in the light reaction more than it is consumed in the subsequent dark reaction.However, by intermittent irradiation with light, it is consumed in the dark reaction. If the amount of NADPH that is consumed is generated by the light reaction, NADPH will not be accumulated, so photosynthesis will not be inhibited and the rate of photosynthesis will increase. (Reference: The World of Photosynthesis, written by Yozo Iwanami, published by Kodansha) In the present invention, before entering the photosynthesis reactor, the sunlight that has been collected by the sunlight concentrator and guided by the light guide means is
The photosynthetic microorganisms are irradiated intermittently using a chopping device or an optical path switching device.

The mirror 13a is positioned so that the angle is 1/2 θ from the path center line 5 toward the direction where the light guide means 3b is arranged, and then sunlight 1 is directed from the light guide means 3 to the light guide means 3c. , the mirror 13a is positioned so that the perpendicular to the mirror 13a is 1/2 θ×2=θ from the path center line of the light guide means 3 toward the direction where the light guide means 3c is arranged. By repeating such rotation of the mirror 13a alternately, the sunlight 1 from the light guiding means 3 is alternately switched to the light guiding means 3b and 3c. When the total number of light guiding means is n including the light guiding means 3, the positions at which the mirror 13a is rotated are 1/2θ, θ, . . . θ/2(n−1). Because it is necessary to rotate the mirror 13a in this way, the electric motor 1
3b is preferably a step motor. In this way, the sunlight 1 that has passed through the optical path switching device 13 becomes intermittent light and is guided to the photosynthesis reactor 5 through the light guiding means 3b and 3c, and the light from the light guiding means 3b is transmitted to the light transmitting rod 4.
In a, the light from the light guide means 3b is supplied into the photosynthesis reactor 5 through the transparent rod 4b. Therefore, the sunlight 1 becomes intermittent light and is alternately irradiated onto the photosynthetic microorganisms around the translucent rod 4a and the photosynthetic microorganisms around the translucent rod 4b.

度を増大させることができるのである。In the case of the configuration shown in Figure 3, a large photosynthetic rate can be obtained by irradiating the photosynthetic microorganisms with intermittent light, which is the same as in the example shown in Figure 1, but in the case of this configuration, this is not the case. In addition, the sunlight 1 can be switched and used by the optical path switching device 13, so the sunlight 1 collected by the sunlight concentrator 2 can be used by switching the sunlight 1.
Since all of the energy can be used effectively without any waste, the photosynthesis rate can be increased by that amount.

However, multiple photosynthetic reactors may be installed, in which case the sunlight 1 will be sequentially switched to irradiate the photosynthetic microorganisms in the multiple photosynthetic reactors, and in this case also, the sunlight concentrator 2 Similarly, the concentrated sunlight 1 can be used effectively.

受光面積を狭小にできるという効果を奏する。According to the present invention, in a photosynthesis reactor system in which sunlight collected by a sunlight concentrator is guided to a photosynthesis reactor by a light guiding means and is irradiated to photosynthetic microorganisms in the photosynthesis reactor to perform photosynthesis, The photosynthetic microorganisms were configured to be irradiated with intermittent light using a chopping device or a light path switching device installed between the light device and the photosynthetic reactor. It is possible to produce an appropriate amount of NADP-#, which is a substance that inhibits the dark reactions that occur in the photosynthesis, and therefore, the rate of photosynthesis can be increased because NADP* is not accumulated. This has the effect of reducing the light receiving area of the solar light concentrator.
