Nitrogen till the root
Nitrogen is an essential element for life, but since its availability is limited it must be recycled. The most important compartment on the planet where it accumulates is the atmosphere (N2). Hence, special bacteria introduce it into the biosphere through a process called fixation. Once there, it is transferred through the food chain from vegetables […]

In addition, each of the astronauts will take 2 kilos of bacteria in his digestive, the intestinal flora that any human needs to survive. We fly from intestinal Crohn’s […]
