Detecting bacteria that live on Mars

Scientists have found a bacterium that can grow in the icy region of Canada, at cold temperatures like on Mars.

According to a report by scientists from McGill University, Montreal, France, the bacterium named Planococcus halocryophilus OR1 can grow at -15 degrees Celsius, the coldest temperature that bacteria can survive. record.

This discovery has brought new suggestions for the prerequisites for a biological life on another planet, such as on the Saturn Moon or on Mars. These are also the two planets that are thought to exist under the surface of the frozen ocean.

Bacteria were discovered after scientists scanned over 200 bacteria to look for a micro-organic organism, able to survive in the harsh conditions of permafrost.

Ellesmere Island, Canada, where the bacterium can live on Mars.

'We believe these bacteria have lived on saltwater circuits in permafrost on Ellesmere Island, Canada. The salt in these icy oceans has caused the water to freeze in freezing temperatures, creating a habitable environment, although harsh for bacteria , 'said Lyle Whyte, a scientist. .

Although it is not easy to survive in this environment, organic organizations can still survive at -25 degrees Celsius in freezing conditions. The reason is that this type of bacteria has changed in cell structure and function to adapt to harsh living conditions.
