  • DEVICE FOR ENRICHMENT CULTURE AND GRAVITY-TYPE ISOLATION OF MARINE MICROORGANISMS IN HIGH-PRESSURE ENVIRONMENT
    Publication number: 20240124827
    Abstract: The present invention provides a device for enrichment culture and gravity-type isolation of marine microorganisms in a high-pressure environment. The device includes an enrichment and multistage purification unit and a gravity-type isolation and culture unit. Under a high-pressure and low-temperature environment constructed to be consistent with a marine environment, the enrichment and multistage purification unit is used for realizing a process of enrichment and multistage purification of the marine microorganisms, obtaining a marine microorganism enrichment bacteria liquid and injecting the marine microorganism enrichment bacteria liquid into the gravity-type isolation and culture unit. The gravity-type isolation and culture unit is used for carrying out automatic streaking by means of gravity in the high-pressure environment to achieve solid isolation and culture of the marine microorganisms, such that culturability of the marine microorganisms is effectively improved.
