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 bioreactor is provided with chemosynthetic bacteria, and the hydrogen is supplied by supplying a dissolved hydrogen solution to the bioreactor.

To provide a method for producing basic chemicals that can produce basic chemicals from hydrogen and carbon dioxide using chemosynthetic bacteria and a simpler basic chemical production system, and to provide the basic chemical production system. [Solution] A method for producing basic chemicals, which includes supplying carbon dioxide and hydrogen to a bioreactor and reacting them, wherein the bioreactor is equipped with chemosynthetic bacteria, and the hydrogen is supplied by supplying a hydrogen solution to the bioreactor.

The invention belongs to an in-situ leaching uranium mining process, and particularly relates to an autotrophic microorganism in-situ leaching uranium mining process under an original ore control condition. An autotrophic microorganism in-situ leaching uranium mining process under the original ore control condition comprises the following steps that after strains are put into a stope liquid injection system with the leaching depth being 80-950 m, a large amount of inorganic carbon and inorganic nitride in an ore-bearing and water-bearing layer with the depth being 80-950 m are used as energy, energy for maintaining self breeding and growth is obtained through the chemical energy synthesis effect, and then the self-breeding uranium mining process is completed. And the population number is increased. The method has the remarkable effects that autotrophic microorganisms of inorganic carbon sources and nitrogen sources are utilized to secrete oxidizing substances or complexing substances capable of being identical with metal uranium Luhe in the metabolic process through biological action, and leaching of the sandstone type uranium ore can be achieved only by supplementing part of oxidizing agents or complexing agents. The engineering technical problems that in the traditional microbiological leaching process, strain breeding is difficult, the number of populations is difficult to maintain, and the leaching effect is poor can be effectively solved.

The invention described herein presents compositions and methods for a multistep biological and chemical process for the capture and conversion of carbon dioxide and / or other forms of inorganic carbon into organic chemicals including biofuels or other useful industrial, chemical, pharmaceutical, or biomass products. One or more process steps utilizes chemoautotrophic microorganisms to fix inorganic carbon into organic compounds through chemosynthesis. An additional feature described are process steps whereby electron donors used for the chemosynthetic fixation of carbon are generated by chemical or electrochemical means, or are produced from inorganic or waste sources. An additional feature described are process steps for recovery of useful chemicals produced by the carbon dioxide capture and conversion process, both from chemosynthetic reaction steps, as well as from non-biological reaction steps.

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.
