Scientists find bacterium that gets energy of hydrogen

n international team of researchers found for the first time, in the abissais deepenings of the ocean, bacteria that use hydrogen as power plant to produce substance organic, informed in this Wednesday the National Center of Scientific Research of France (CNRS, in the acronym in Frenchman).

The results of the research, carried through with the German institute Max Planck and the University of Harvard, U.S.A., and published for the scientific magazine “Nature”, open “interesting perspectives” in the sector of the biotechnologies and of the energies you renewed, according to a note of the CNRS.



The scientists had found the bacteria the 3,2 a thousand meters of depth in the field of Logatchev, a submarine mountain range in the way it way between the Caribbean and the African islands of Green Handle.

The region is a zone of production of hidrotermal energy in which these organisms, that live in symbiosis with mussel banks, consume up to 50% of set free hydrogen.

According to given collected, in the analyzed extension of land they are consumed up to 39 million liters of hydrogen per year.

The researchers had also discovered that the responsible gene for the chemical transformation of hydrogen can be found equally in bacteria that live in association with other hidrotermais organisms, as worms and shrimps.

“The discovery implies that the capacity to use hydrogen as power plant is habitual (...) in the places where the hydrogen abunda”, designated the CNRS.

These “extreme” ecosystems interest particularly the scientists for sheltering conditions in which if they develop forms of primary life on the Land, it explained the French center.

In these hidrotermais zones, the animals live in symbiosis with bacteria that are capable to produce organic substance by means of the transformation of chemical energy, instead of making it by means of the luminous energy, as in the case of the plants.

Although already they have been discovered capable bacteria of if feeding of methane and sulfureto of hydrogen, the hydrogen use for the same ones results more interesting for the scientists. According to CNRS, its productivity the others are up to 18 times superior of these two power plants.
