An international group of scientists said that they were able to detect microbes that could survive on the surface of Mars. Moreover, according to the researchers, the same microbes can survive on Enceladus, Europe and possibly other celestial bodies of the solar system, – reports 1NEWS.
"Our experiments show that the presence of toxic perchlorates in the soil of Mars is not necessary says that life is not there.It is possible that bacteria grow even in" brines " very strong, including a dozen perchlorates.It is ten times less on Mars, "said Jacob Heinz, one of the researchers
During the study, scientists raised bacteria found in lakes sublime Arctic and Antarctic in solutions containing various salts, including toxic perchlorates, common soda, calcium chlorides and magnesium. Researchers investigated whether bacteria could survive under such conditions and, if possible, what levels of salts would support their lives.
As a result, scientists have established that under these conditions, at least one terrestrial bacterium – Planococcus halocryophilus, whose colonies were found in permafrost deposits in Canada about six years ago
At the same time The bacteria survived at low temperatures (about -30 degrees Celsius) and the survival rates were the lowest. As the researchers point out, to reduce the freezing point of the solution, the dose of perchlorate should be at least 50%, so the low survival rate of bacteria under such conditions is a miracle.
