Study: Several Types of Siberian Bacteria Could Survive on Mars

by Colonel on December 25, 2012

“Some of the genus Carnobacterium microbes have already been found to exist in cold climates around the world. …

Researchers from the Department of Microbiology & Cell Science at the University of Florida took samples of bacteria from the sand deposits, on the bank of the Kolyma River in northeastern Siberia.

After extracting the samples from a depth of 12-20 meters where the soil has an average annual temperature of -7 °C, scientists grew bacterial colonies at 28 °C in normal atmospheric conditions.

The bacteria were then tested in Martian conditions – exposed to a lack of oxygen, extremely negative temperatures, and very low pressure – which hinder the growth of most terrestrial microorganisms.

After the 30-day experiment, only six of the 10,000 isolates were able to grow under these conditions.

All of the surviving isolates were members of the genus Carnobacterium.
