Found bacteria can make oxygen to respire

Scientists at the Nijmegen University in the Netherlands have discovered a bacterium that can produce oxygen to breathe.

This finding has important implications in the study of changing the life of the Earth and searching for alien life.

In the latest issue of the British issue of Nature, the scientists said that the type of bacteria they discovered could exist in a completely oxygen-free environment, but must be in the body. The amount of oxygen needed can complete the metabolic mechanism.

Research has shown that this bacterium relies on a special proteolytic protein to perform resolution of nitrogen oxide into nitrogen and oxygen.

In the past, scientists only knew the principle of creating oxygen under the combined effect of a few organisms.

However, traces of Earth's life-changing history have shown that, before large amounts of oxygen are produced under photosynthesis by plants, there are a number of microorganisms that can produce themselves. oxygen to respiration. And this has caused much controversy in academia.

Scientist Katarina Aiteweige, a member of the research team, said the findings suggest that some species of microorganisms can create oxygen themselves to breathe.

Because the food of this bacterium is methane, while on the stars, especially Mars, there is a certain amount of this gas.

Therefore, scientists believe that on other celestial bodies there is also the possibility of some species that can only exist in an oxygen-free environment.
