Found terrestrial bacteria

team of scientists from Oregon (United States) culture bacteria collected in the ice lava tubes in the Cascade Mountains and found that they can live in the harsh environment of Mars. These germs can live in conditions of low temperatures and lack of oxygen, they also grow in the absence of organic food. Their metabolism is based on the oxidation of iron from olivine, "ordinary" volcanic mineral. These factors would provide all the necessary microbes to exist in conditions of Mars and other planets like him. American scientists found a microorganism widely distributed in the world and lives on the ocean floor, in caves, soil and even human skin. Nevertheless, it is unique and could comfortably exist even in such an inhospitable place like Mars.

In the laboratory at room temperature and normal level of oxygen "Martian" microbes can consume organic matter, in particular sugar. But as organic food disappears, the temperature drops to zero and the sharply reduced level of oxygen, bacteria can easily pass on the mineral food that is contained in the volcanic rock. C this phenomenon scientists have not previously encountered. The fact that at high temperatures, usually in volcanic rocks atmospheric oxygen oxidizes iron before the bacteria start to eat them. However, lava tubes, where the bacteria are covered with ice and protected from the atmosphere, are very comfortable to hold an "iron food." Sure, on the surface of Mars, conditions are more severe than on Earth. However, in the depths of the warm rocks such bacteria can survive successfully. Once the temperature and the atmospheric pressure on Mars were higher than they are now, and the bacteria could easily master the Red Planet. So today there is hope to find traces of these microorganisms. Also, it is possible that in the warm depths of the Martian colonies of microorganisms are still alive, but so far to get to them there is no way.
