Bacteria can help feed astronauts on Mars


Astrobiologists found that cyanobacteria can produce oxygen, sugar, amino acids and other nutrients under Mars.

Given the current technical development and features of the rotation of the planets of the solar system, Martian missions involving a person can delay for several years. One of the key problems is the supplies, more precisely the volume necessary for the successful return of astronauts to the Earth. Since sending sufficient quantity into space will be exorbitantly expensive, scientists are looking for the best ways to produce the necessary substances and materials during the mission itself.

The team of researchers from the University of Bremen studied cyanobacteria Anabaena, which can produce oxygen and converting atmospheric nitrogen to sugar, amino acids and other nutrients necessary to maintain human life and other organisms.

In the course of experiments, scientists were able to grow microorganisms in a bioreactor at low pressure in artificial Martian soil and atmosphere. However, astobiologists had to increase the pressure in the installation of up to 10% of the earth, so that water could exist in liquid form on the surface of the solid medium.

In such conditions, the studied Anabaena grew quite well for efficient use for the production of nutrients.
