15 million year-old bacteria found in Antarctic

Russian researchers at the beginning of last year managed to reach drilling the Lake Vostok in Antarctica 15 million years, so far not precedent was announced that a bacterium. Located approximately 3800 meters below the ice layer of bacteria, isolated from the outside world in a way that 15 million years to live.

Russian researchers drilling completed in February 2012 , Antarctica 's largest underground lake 3769 meters in depth , which had managed to reach Lake Vostok . Russian scientists , in the samples taken from the lake , so far not found anywhere else in the world to allow a species said they had found .

RIA Novosti news agency made ??a statement St . Petersburg Institute of Physics Sergei Bulat, " we found that the bacteria identified so far I would say that there is a certain class ," he said .

The analyzes performed on the DNA of bacteria , 86 percent of the genetic structure of living , is different from known bacteria revealed. Bulat, of the findings , ' a new species of bacteria pointed out that ' he said .


NEW SAMPLES COLLECTED will
Thanks to its geological characteristics of Jupiter's moon Europa and Saturn 's moon Enceladus in order to understand the geographic features of great importance in Lake Vostok , for millions of years have passed very different geo- chemical processes . On a layer of ice , Lake Vostok , at least 400 thousand years passed from the process engendered a paleoclimate scientists allowed on the lake so far not encountered species can be found stated.

Russian investigators 'unknown bacteria ' after the discovery in May, taking new samples from the lake said they would carry out a new analysis .

Approximately 250 kilometers in length, carrying the first sample taken from Lake Vostok Russian Academic Fyodorov research vessel in May 2012, St . Petersburg had reached the city . 50 miles wide and 800 feet deep in Lake Vostok in the Antarctic, as it is completely isolated from the 145 underground lake with a very different geological and geographical features .

EXTRAORDINARY CREATURES
Lake Vostok çoksayı increase the likelihood of the organism to host another feature of the lake is over-saturated with oxygen . The ratio of oxygen in the lake in the world, almost 50 times the rate of oxygen in fresh water Obs .

On especially in the depths of the lake is rich in minerals , the researchers hope to find new species , these creatures ' have managed to adapt to exceptional circumstances ' to be noted.

40 YEAR STUDY
Russians, located at the bottom of Lake Vostok and 40 years, the fruits of their work in Vostok Station, started collecting after many years . Researchers in the glacial Lake Vostok kilometers thick overlying layer , estimates that at least 1 million years .

Scattered throughout the years on Mars, even exceeding cold temperatures ( -72 vicinity) insna employees of Russian science , in order to continue drilling in Lake Vostok has suffered great hardships .

Need fuel and food , fetching from the 1500 km distance , the materials brought on the land with tractors due to technical failures were often caused delays . Russian researchers first discovered Lake Vostok and the potential store who , as a result of long study findings to the scientific world for millions of years began offering is stored .

Antarctica, the world's clean water supply 70 percent of its hosts. 90 percent of this water , is located in the East Antarctic ice .
