Scientists have found bacteria which don't need sunlight
Researchers have found cyanobacteria in Spain which live in cracks and crevices of stones. The group of scientists from Germany, Spain and the USA has found cyanobacteria which can live at a depth more than 600 meters and don't need sunlight. It is reported on the website of National Academy of Sciences of the USA. Researchers have drilled the 613-meter well about the river of Rio Tinto in Spain and have found cyanobacteria which live in cracks and crevices of stones. This opening is important first of all because earlier was considered that such bacteria need for life light and that oxygen has appeared from behind them in the atmosphere of Earth. Cyanobacteria from the well were almost identical to those who can be found on the Earth's surface. Their only difference consisted in ability to absorb hydrogen gas instead of oxygen. For this purpose they use so-called "safety valve" which at other bacteria performs function of release of excess energy for prevention of overheating. Earlier it was reported that coffee machines contain a huge number of bacteria hazardous to health, and it isn't important how the car is often used. News from the Correspondent.netv of Telegram.
