The organisms that live without oxygen

Some discoveries do us change completely our concept of life, and is that they exist some forms that surprise truly by the fact to be able to subsistir in surroundings that for us would be entirely hostile as it is the lack of oxygen. In this occasion go to know some organisms that have been discovered in the subsoil of a mine of Seville that until the moment have been in perfect condition in spite of the hostility of the surroundings and to the absence of air that can be breathed.

The change of the concept of the life

But one of the most interesting appeals of this type of discoveries is that they do us give us account that the life no only bases in the diagram that know, that is to say, exists the possibility to find forms of life entirely distinct to which knew up to now, and of course already are beginning to give the first steps.

In this sense, no longer results so odd to think that there are alive species in our own planet in places totally insospechados up to now, and of course, the fact to pose us the life in other planets also opens considerably, what gives us place to dream with worlds entirely distinct to which can have created in our mind.

The organisms marcianos

And with this nice name have been designated these organisms that keep without an apex of oxygen, breathing so only through the sulphate that finds in the zone.

With the step of the years, this colony of bacteria that live to 150 m of depth, have gone creating rocks until forming a yacimiento that by the moment is only all over the world.

According to the researchers, consider that this same process can be giving in these moments in planets like Mars, by what the study and analysis of these forms of life will allow agrandar the steps to know better the red planet.

The mine of Seville

This mine receives the name of The Crosses, and finds to so only 15 km of Seville.

By the moment so only have been found fossils, but the experts consider almost sure the possibility to find alive rests.

These bacteria have been acting along million years, and by the moment has not achieved indagar much more, but is evident that the evolution of the zone and the increase of 20 m in the thickness shows and evidence that sometime were alive, what would give to understand that they will go on down the zone although they find in distinct layers.

These organisms are designated extremófilos due to the fact that they adapt and has the capacity of subsistir even in extreme conditions as it is the case of our new known that no only lacked oxygen but also they have found during years entirely isolated of the light.

The temperatures in this zone generally oscillate between 30° and 60 °C, in addition to that fits to stand out that the rocks that find on her are waterproof, hampering so any external element could access to this ecosystem.
