Analysis of the first water samples of the Antarctic relict lake The East showed that they practically do not contain microorganisms, and therefore, the upper layers of water in this lake can be sterile, said Sergey Bulat, head of the cryoastrobiology group Laboratory of Eukaryotic Genetics, St. Petersburg Nuclear Institute physics. 
Photos from open sources to Russian scientists in February 2012 after many years of drilling, they managed to enter the lake for the first time East, which for millions of years has been isolated from the outside world is four kilometer thick ice. Scientists hope detect relict organisms that could adapt to life in the conditions of eternal darkness of an icy lake. IN February, drilling was stopped, scientists in December 2012 plan to return to “drill” freshly frozen lake water. However, part of the lake water froze on a drill, its scientists studied now. Bulat introduced the first “very preliminary” analysis results at a conference in Stockholm, according to the publication Nature News. Russian scientists have calculated the amount microorganisms caught in water samples, and also carried them genetic analysis. The number of microbes in lake water turned out less than 10 per milliliter. Approximately as many microorganisms could get into samples already in the laboratory. Moreover, three out of four types of microbes found during genetic analysis water from the silicone oil used in the drilling, and the fourth turned out to be unknown, but most likely also related substance. Damask hopes to get clean samples from frozen in the borehole of lake water, however, they will not reach St. Petersburg earlier May 2013, when the Antarctic expedition returns to the city. The scientist emphasizes that although microbes may not be in the upper water layers of the lake, they can be found in bottom sediments. Earlier, Bulat said that in the thickness of the water of Lake Vostok they can live only absolutely new living things not known to modern science organisms that can exist at ultrahigh oxygen concentration.
