Scientists from the University of California at Davis found a bacterium that multiplies in space by 60% more active than on Earth. The results of the work can be found in the journal PeerJ and brief them on the reports RNS .

As part of the research on the International Space Station (ISS) 48 strains of non-pathogenic micro-organisms have been sent. The conditions under which the microorganisms are, as follows: the temperature was 22 ° C, humidity – 60%, pressure and oxygen concentration were close to those in the world. It was found that the bacterium Bacillus safensis JPL-MERTA-8-2, found on the spacecraft Mars Exploration Rover project in 2004, bred in space by 60% faster, while the behavior of other microorganisms has not changed.

The most obvious difference between the two environments is the force of gravity, however, according to the study authors, a microbiologist at the University of California, David Koila, it is unlikely that it is important for the individual micro-organisms. “Microorganisms are small enough so the force of gravity is not the determining factor for their daily metabolism and physiology,” – he said the scientist

Scientists have deciphered the genome of Bacillus safensis and plan to carry out comprehensive tests with microbes to find out on. what specific factors they respond most strongly
