German scientists concluded that it was possible to create survival systems based on cyanobacteria or “green-blue” algae, which would be able to live on the surface of Mars.

According to the study, published in the journal “Frontiers in Microbiology”, a team of researchers from the University of Bremen in Germany was able to discover microorganisms capable of growing and developing in the Martian atmosphere.

Researchers believe it’s possible to create survival systems for humans that rely on cyanobacteria or blue-green algae, which could live on the surface of the Red Planet.

Experience has shown that these microorganisms could remain active by using gases from the Martian atmosphere as a source of carbon and oxygen, despite the low pressure.

The possibility of preserving living beings

These blue-green algae reproduced in the water, where Martian dust was left in suspension, allowing, according to the study, to be used as food for other organisms.

In addition, cyanobacteria produce oxygen as a byproduct of photosynthesis.

For this experiment, the scientists developed an “Atmo” bioreactor, which maintained conditions close to those of Mars.

The researchers also selected a type of nitrogen-fixing cyanobacteria called Anabaena sp “PCC 7938”, and preliminary test results revealed it was likely to adapt to conditions on Mars.

According to the study, although bacteria thrive best in a nutrient medium, scientists have also observed growth of Martian regolith, which is a fine dust covering the planet.
