    Directly hit the east Pacific Ocean 5200 meters under the sea floor, deep-sea microorganisms refresh human cognition.
    ginseng, red prawns, small white fish, blue anemones... Colorful life in the bottom of the sea a cheerful swim, staged a birth movement of the "underwater mobilization."
    more than 5,000 meters bed, self-returning deep-sea biophotography and sampling system to shoot long shrimp.
    ,000 metres bed, long-tailed cod photographed by home-grown deep-sea biophotography and sampling systems.
    " using deep-sea cameras, we clearly observed the 5,200 meters of the sea floor of the lively scene, in fact, those invisible to the naked eye is the hidden deep-sea 'main character'.
    Lin Hui, chief scientist of the 45th China Ocean Voyage, told Science and Technology Daily that in recent days, the Ocean 45 Flight Science And Research Team has conducted intensive investigations into deep-sea microbial strains and their genetic resources in the eastern Pacific Ocean, using large-scale investigation and in-place rich culture.
    Previously, the genetic survey of deep-sea organisms in China was mostly concentrated in the south-west Indian Ocean, the South Atlantic and the Eastern Pacific Ocean in the mid-ridge geothermal region, and there were relatively few investigations in the deep-sea plains similar to the polymetallic nodding zone in the eastern Pacific Ocean.
    to the depths of the ocean at a depth of several thousand meters at a depth of 5,200 meters, high pressure, darkness and cold, which were once considered a no-go zone for human life.
    less than 1% of deep-sea microorganisms are currently known to humans, and little is known about the life activities and energy metabolism processes of microorganisms in the subsea environment.
    in-place collection system for the recovery of deep-sea microorganisms is not only the case, but also the current world-largest technological bottleneck in the land laboratory, which fully simulates the deep-sea environment to culture microorganisms.
    Just a few days ago, ocean 45 voyages successfully recovered the deep-sea microbial in-place rich system, which "moved" the laboratory to the bottom of the sea more than 5,200 meters, using extreme environments such as high pressure, low temperature, oligotrophic nutrition in place in the deep sea and open material exchange conditions to collect and cultivate marine microorganisms that are not available in land laboratories.
    "We use membranes to intercept in-place rich bacteria obtained from different substrates for population structure analysis.
    ," said Dr. Chunming Dong, from the National Oceanic Administration's Key Laboratory for Marine Living Genetic Resources.
    Microbes are a unique resource for the development of new drugs" Extreme deep-sea environments give microorganisms unique population structures and metabolic mechanisms, containing extreme bacteria such as pressure, chills and functions to be identified.
    value of deep-sea microbial resources is reflected in scientific research and applications.
    Zongze, director of the National Oceanic Administration's Key Laboratory for Marine Biological Genetic Resources, said that conducting research on deep-sea microbial genes could help us explore the origins and evolutionary mechanisms of deep-sea life.
    while promoting the steady progress of basic research, deep-sea microbial resources have made important progress in biomedicine, industry and agriculture, food, environment and other fields, and billions of dollars of industry have been formed.
    " special metabolic pathways of deep-sea microorganisms will produce a large number of new drug candidates, providing unique resources for the development of biotechnology industry and the development of new drugs.
    , the researchers have isolated and identified 50 small molecular compounds with anti-tumor, anti-aging, antioxidant or antibacterial, antiviral and other activities.
    , the deep-sea microbial anti-super-resistant bacteria MRSA and influenza virus H1N1 new structural compounds have been patented, and will enter the pharmaceutical evaluation process.
    that after 15 years of unremitting efforts, China has built the world's leading marine microbial resource bank in the amount and variety of microbial resources.
    " China ranks among the top in the world in terms of the number of resources, but pays insufficient attention to the relevant data mining, development and utilization, as well as intellectual property protection.
    , the interim party secretary of Ocean 45, admitted.
    compared with developed countries, China's deep-sea survey and sample collection technology needs to be strengthened, observation and sampling tools are gradually improved, biological resources research and development also need to complement the short board.
    , " admitted Mr. Zongze.
