Similar to the paste rocks on Mars may indicate the existence of life

Похожие на пасту камни на Марсе могут указывать на существование жизни

Scientists believe that the Mars Rovers have to check these stones on the existence of bacteria.

American scientists announced that the Mars Rovers have to check for the existence of bacteria in rocks on the red planet, similar in shape to the pasta. As reported by the online edition of the Chronicle.info with reference to zn.ua similar structures are formed on Earth.

On our planet such structures are formed under the action of Sulfurihydrogenibium yellowstonense. It belongs to extremophiles, and thus can potentially exist in the Martian conditions.

The bacterium belongs to the line, which began to evolve before the Earth’s atmosphere began to appear oxygen. Such bacteria can survive in extreme conditions, right next to geothermal sources. In addition, they can also withstand intense ultraviolet radiation, and to survive in environments with low oxygen levels.

Sulfurihydrogenibium yellowstonense catalyzes the formation of crystalline rocks that look like layers of pasta. The unique shape and structure of the rocks associated with yellowstonense Sulfurihydrogenibium, are the result of her unusual lifestyle. In fast flowing water bacteria clinging to each other and “keep struggling”. They form tight strands, fluttering like a flag. They are visible to the human eye and more like a fettuccine pasta.

Disclosed the mysterious “observers” ancient disaster

The team analyzed microbial genomes, assessed which genes are most active expression, and deciphered the metabolic needs of these bacteria. Scientists have also explored the possibility Sulfurihydrogenibium yellowstonense in the field of rock construction. I found an interesting fact: the proteins on the surface of bacteria accelerate the rate of crystallization of calcium carbonate around bacterial filaments within them. Thanks to proteins, this process occurs in the threads a billion times faster than any other natural environment on Earth. The result is a wide strip of the hardened breed with a wavy threadlike texture.
