High-pressure environment marine microorganism solid separation culture device and culture method

Abstract

The invention provides a high-pressure environment marine microorganism solid separation culture device which comprises a high-pressure microorganism separation culture chamber, a liquid injection unit, a temperature control system and a pressure control system, the liquid injection unit injects deep-sea microorganism enrichment liquid into the high-pressure microorganism separation culture chamber, automatic streak separation operation is carried out on microorganisms in the high-pressure microorganism separation culture chamber, and the area is provided for microorganism culture to the maximum extent; the temperature control system and the pressure control system are used for constructing a high-pressure and low-temperature environment consistent with the marine environment in the high-pressure microorganism separation culture chamber, so that the enriched deep-sea microorganisms are separated and cultured under the in-situ environment condition. The invention further provides a high-pressure environment marine microorganism solid separation culture method, the in-situ marine temperature and pressure environment is constructed, automatic scribing is conducted in the high-pressure environment, solid separation and culture of microorganisms are achieved, and the culturability of the marine microorganisms is effectively improved.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a device for solid separation and cultivation of marine microorganisms in a high-pressure environment and a cultivation method. Background technique [0002] The ocean accounts for 71% of the earth's area, and marine microorganisms have a completely different ecological community structure and species diversity from terrestrial microorganisms. Deep-sea microbial resources are important strategic resources of the country, so they have also become a hot spot for development in various countries. The diversity of marine microorganisms determines its genetic diversity, metabolic diversity, chemical diversity and functional diversity. Marine microorganisms have formed unique and diverse adaptation mechanisms in the unique marine environment to cope with extreme environments such as high pressure, darkness, high salinity, high temperature, low temperature, and oligot...

AI Technical Summary

Problems solved by technology

Although it can realize the enrichment and cultivation of microorganisms in the deep sea in situ, it does not separate and cultivate marine microorganisms, which cannot effectively improve the success rate of cultivation
