In space, the less antibiotics affect bacteria (3 photos)
On our planet and in space bacteria function differently. To protect astronauts while traveling, it is important to understand the mechanics of these processes. This is required to ensure the safety of space bodies on which they fall.
Scientists from located in boulder the University of Colorado proposed the experiment, performed recently on the ISS. Culture of coliform bacteria poured a powerful antibiotic gentamicin sulfate. As a rule, he easily kills her. In space, the algorithm is lost.
E. coli responded to the sulfate effect gentamicin thirteen-time increase in the number of cells. In parallel, the volume decreased by seventy-three per cent. Bacteria vigorously defended: the outer membrane and the inner wall was thick. Scientists noted a significant amount of membrane bubbles. These miniature capsules of E. Coli-the bacteria used for initiation of infection.
The researchers reported that these processes show activation of mechanisms of drug resistance. The experiments will be continued. But now experts have useful data on the effects of lack of gravity on bacteria. Moreover, microorganisms showed an incredible endurance. They might be able to cope with long flights in space. Wouldn’t they first ispfargoni on distant planets?
