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.

Abstract: The present invention provides a device for single-cell high-throughput sorting in a marine in-situ environment. The device includes a pressure-resistant visual sorting cabin, an optical identification system and an automatic sorting system; a microorganism-containing bacteria liquid is injected into the pressure-resistant visual sorting cabin; the enriched microorganisms is dispersed and pass through a channel via a carrier chip disposed in the pressure-resistant visual sorting cabin; when the enriched microorganisms pass through the carrier chip, the microorganisms are observed and identified via the optical identification system; and the automatic sorting system automatically sorts the microorganisms according to a microorganism identification result. The present invention further provides a method for single-cell high-throughput sorting in the marine in-situ environment.

Abstract: The present invention provides a system and a method for simulating formation and evolution of a deep-sea cold seep ecosystem. Simulation of the cold seep ecosystem is realized and a unit above seabed interface, a seabed interface ecosystem simulation unit, and a subsea interface unit is formed through the system, which provides environmental conditions for evolution of the cold seep ecosystem. At the same, the primary succession and secondary succession of the ecological cold seep system are simulated through the environmental condition control equipment, the sampling cabin, and the seabed current injection system, and the formation environment of the system is remodeled in situ, thereby effectively shortening the period of field observation to research the cold seep ecosystem.
