Our planet is literally impregnated with life: scientists find living organisms in such extreme conditions, where their existence seemingly impossible. And some of them are impressive especially strongly. For example, bacteria hyperthermophilic, living at extremely high temperatures. In the natural habitat, a man would not live a dozen seconds. Comfortable temperature for most hyperthermophil starts from 80 ° C, but some feel light cool at a temperature of 100 ° C.
For the first time, hyperthermophils were discovered in 1969 in the hot springs of the Yellowstone Park. After that, such organisms began to find in hydrothermal sources around the world, and at the moment there are just more than 70 species of these bacteria. They are obliged to enzymes, the structure of which allows them not to collapse with severe heating.
The record holder in a flattened temperature, in which the normal activity of the body remains, is the view of Methanopyrus Kandleri, discovered on the walls of the hydrothermal source at a depth of 2000 meters in the California Gulf. Methanopyrus Kandleri is capable of multiplying normally and function at 122 ° C.
Of particular interest is the recent view of the "strain 121". The normal temperature of its habitat is 121 ° C, but during the experiment, scientists placed this type of medium with a temperature of 130 ° C, which he kept for 2 hours! "Strain 121" stopped multiplying in such extreme conditions, but did not die, completely retaining his life functions. Returning the bacteria into the "normal" conditions at 121 ° C, scientists saw that hyperthermophiles, as if nothing had happened again, began to multiply. At the moment, it is the "strain 121" belongs to the record at the maximum weathered temperature among all living organisms on the planet.
The existence of hyperthermophils can explain how life on earth was able to survive such cataclysms as a global cooling that occurred about 800 million years ago, when the entire planet was covered with a thick layer of ice, and the average temperature at the equator was 50 ° C. Probably, in those days, life continued only in deep-water thermal sources, where at high temperatures a colony of hyperthermophils lived. In addition, hyperthermophils give us an idea of what an alien life may be, and that previously considered unsuitable for life because of its high temperature of the planet may well be inhabited by tiny microorganisms.
