Impressive variety of unknown microbes thrive in an area between 6 and 11 km below the surface.
A Zona talk, which includes the depths of the Marian pit, it is a very challenging habitat, with temperatures close to the freezing point, immense pressure and where the nutrients are rare.
But there there. And a new reveals 7,564 new species of microbes; almost 90% They were unknown by science so far.
That is, it was discovered an impressive variety of unknown microbes, which thrive in the extreme conditions of the Hadal Zone of the Ocean, between 6 and 11 km below the surface.
In this analysis, scientists dived 33 times in the pit in a submersible. They collected seawater samples and sediments to various depths.
The study highlights two strategies Main that microbes use to survive: some have evolved with smaller and efficient genomes, designed to resist extreme pressures and low temperatures from the ocean bottom; Others have larger and more versatile genomes, allowing them to adapt to scenarios that are changing and using a wide range of materials to eat.
The investigators, continues the, observed a significant variation In microbial communities from different places, suggesting that the unique topography of the ocean fund plays an important role in the formation of these ecosystems.
To great depths, the cooperation Microbial seems to be crucial to survival: some microbes formed biofilms and shared nutrients in closely linked communities.
This study can give biologists new resources to use the conclusions in various fields, since medicine has Evolutionary investigation.
