the first American scientists have found microbes beneath the ice Antarctic lake. Bacterial community pond existed in complete isolation, hundreds of thousands of years.
This is stated in the article from the University of Montana,
published in the latest issue of the journal Nature.
Bacterial RNA was isolated from the samples, scientists,
taken from the subglacial lake Uillans in January 2013. This lake,
Located 650 kilometers from the South Pole, hidden under a 800-meter layer
ice, its depth is only 1.5 meters. Experts have all
possible, so as not to contaminate the sample with modern bacteria.
Most microorganisms identified in lake water, refer to the Archean,
a special group that is different from the rest of the bacteria. The most abundant of these
representatives Nitrotoga arctica, constituting 13% of the lake microbes. They
live at the expense of nitrification - the oxidation of ammonia, which is rich in
lake.
In one milliliter of water contains Uillans about 130,000 bacteria of
They have both sticks and cocci. Organic and mineral substances, by
microorganisms which live in the lake, there were about a million years ago -
that's when the last time it was contacted with the surface.
Earlier, Russian scientists have already made it to the subglacial Lake Vostok, however,
Unlike their American counterparts, they were not able to get water from it. In the hands of our
compatriots hit the ice of the frozen on the storm that affected the results
research. In total there are more than 400 Antarctic subglacial lakes. By
According to the authors, many of them also have a life.
