Deep sea thermal solution simulation and high-temperature high-pressure microorganism culture system

Abstract

The invention relates to the technical field of environmental simulation and microorganism culture, and in particular relates to a deep sea thermal solution simulation and high-temperature high-pressure microorganism culture system comprising a gas and liquid transmission pipeline, and further comprising a high-pressure substrate batching unit for uniformly mixing high-pressure gas and high-pressure seawater to obtain a high-pressure seawater culture medium dissolved with high-concentration gas, a high-temperature high-pressure culture unit for acquiring the high-pressure seawater culture medium from the high-pressure substrate batching unit to breed microorganism, a gas supply unit for providing high-pressure gas for the high-pressure substrate batching unit and the high-temperature high-pressure culture unit, a flow control unit for controlling pressure in the high-pressure substrate batching unit and the high-temperature high-pressure culture unit as well as a flow velocity in a continuous culture process, and a gas monitoring control unit for detecting concentration of combustible gas in an environment, judging leakage of the combustible gas in the high-pressure substrate batching unit and the high-temperature high-pressure culture unit, and alarming in real time or automatically cutting off gas supply of the gas supply unit depending on a judgment result.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a deep-sea hydrothermal simulation and high-temperature and high-pressure microorganism cultivation system. Background technique [0002] The deep sea is the largest independent ecosystem in the world, including deep seawater (deeplayer water), surface sediment (toplayers sediment), and geological structures such as cold seep, hydrothermal vent, and metallic nodules. The microbial biomass in the deep biosphere accounts for 90% of the global total. The microorganisms detected from the deep sea are significantly different from those in other environments, and have unique metabolic pathways, signal transduction and defense mechanisms. They are living fossils for the study of early life processes and the evolution of the earth's environment, and have irreplaceable scientific value. Containing the most abundant microbial resources, it is the "common heritage of mank...

AI Technical Summary

Problems solved by technology

Due to technical limitations, it is difficult to simultaneously control environmental parameters such as high temperature, high pressure, and continuous flow culture with gas substrates. Therefore, it is difficult to simulate deep-sea hydrothermal systems and culture microorganisms, which has led to the development of energy systems in the world. There are very few research teams on deep-sea thermobarophilic microorganisms and ecosystems
