This invention provides a method and system for culturing chemosynthetic autotrophic bacteria that enable safe operation while maintaining high culture efficiency. [Solution] A method for culturing chemosynthetic autotrophic bacteria comprises a gas supply step of supplying hydrogen, oxygen, and carbon dioxide to a culture medium containing chemosynthetic autotrophic bacteria; a mixed gas recovery step of recovering gases not dissolved in the culture medium as a mixed gas; and a maintenance step of maintaining the mixed gas so that the oxygen content is less than 5% by volume or the hydrogen content is less than 4% by volume. A culture system for chemosynthetic autotrophic bacteria comprises a gas supply means of supplying hydrogen, oxygen, and carbon dioxide to a culture medium containing chemosynthetic autotrophic bacteria; a mixed gas recovery means of recovering gases not dissolved in the culture medium as a mixed gas; and a maintenance means of maintaining the mixed gas so that the oxygen content is less than 5% by volume or the hydrogen content is less than 4% by volume.

When a valuable material is produced in a bioreactor using chemosynthetic bacteria, the present invention makes it possible to avoid a decline in the production efficiency. This supply system includes: a hydrogen dissolution facility that dissolves, into a culture medium, hydrogen contained in a first gas generated by a prescribed plant; and a carbon dioxide control facility that controls the amount of carbon dioxide, which is contained in a second gas, to be supplied to a bioreactor loaded with a culture medium containing chemosynthetic bacteria. The supply system supplies the culture medium with hydrogen dissolved therein and the carbon dioxide to the bioreactor. The hydrogen dissolution facility includes: a culture medium tank loaded with a culture medium; a first gas supply path for supplying the first gas to the culture medium tank; and a first gas return path for returning the first gas discharged from the culture medium tank to the source from which the first gas has been generated.

The present invention relates to a method for producing a basic chemical that includes supplying and reacting carbon dioxide and hydrogen in a bioreactor. The bioreactor is provided with chemosynthetic bacteria, and the hydrogen is supplied by supplying a dissolved hydrogen solution to the bioreactor.

This invention discloses an indoor oxygen-enhancing ecological wall based on plant chemosynthesis, comprising a wall body with a fixed support frame installed on it. An aquatic animal breeding pond is located at the bottom of the fixed support frame. Above the aquatic animal breeding pond are multiple layers of planting frames for growing greenery. Water pipes are connected between adjacent planting frames. The planting frames and water pipes are arranged in an S-shaped structure. A water replenishment device is located between the top planting frames and the aquatic animal breeding pond, and this device is connected to a controller. A water return device is located between the bottom planting frames and the aquatic animal breeding pond. A supplemental lighting device is installed on the fixed support frame and connected to the controller. This device provides supplemental lighting to the greenery. This invention increases light intensity for the plants through the supplemental lighting device, thereby increasing photosynthesis and promoting normal plant growth and development, while also improving indoor air quality.
