This spring, the Internet was an active debate about the long-drilling operations on Lake Vostok in Antarctica, which finished water sampling and sending them to the mainland. All hoped that the permafrost in the "sealed" for millions of years the pond there is something that will revolutionize our understanding of the world, or to give impetus to science. And finally made public the results of the examination …
Scientists hope to find in the samples relic organisms that have adapted to a life of eternal darkness under the ice of the lake.
In February, the drilling was stopped, the scientists in December 2012 plan to return to "vyburit" svezhezamerzshuyu lake water. However, part of the lake water was frozen on the drilling assembly, the researchers looked at her now. Bulat introduced the first "very preliminary" analysis results at a conference in Stockholm, said the publication Nature News.
Russian scientists have estimated the number of micro-organisms trapped in water samples, and conducted their genetic analysis. The number of bacteria in the lake water was less than 10 per milliliter. Approximately the number of microorganisms have been caught in the samples are in the lab.
However, three of the four types of microbes found in the genetic analysis of the water were used in the silicone oil drilling, and the fourth was unknown, but probably also related to the substance.
Bulat hopes to get pure samples of the frozen lake water in the well, but they get to St. Petersburg until May 2013, when the city will return Antarctic expedition.
Scientists emphasize that although microbes may not be in the upper layers of the lake water, they can be found in the sediments.
Earlier Bulat said that in the water of Lake Vostok may inhabit only brand new, not known to modern science of living organisms that are able to exist at an extremely high concentration of oxygen.
