Bacterium from Canadian high Arctic has been found to
survive on most downfallen (permafrost) temperatures easily. The frosting
temperature on Ellesmere Island, Canadian high Arctic is closely similar to
that of the surface of Mars. Hence, this special organism has shown new
possibilities of Life on Mars as well as one of the moons of Saturn, Enceladus.
The surface temperature of Mars and Enceladus holds subzero conditions where
life cannot be expected, however, this bacterium offered an ease in surviving
in conditions similar to subzero conditions, i.e. temperature below -15ºC.
The new founding had been made recently by McGill University and their
scientists on a bacterium.

The team of researchers did screening of about two hundred
different microbes to find the most able microorganisms that may survive in the
lowest temperature conditions of the Arctic, and discovered a bacterium ‘Planococcus
halocryophilus OR1’ from Ellesmere Island of the Canadian high Arctic.
The team leader, Professor Lyle Whyte from the Department of
Natural Resource Sciences at McGill University said, “We believe that this bacterium
lives in thin veins of very salty water found within the frozen permafrost on
Ellesmere Island”. "The salt in the permafrost brine
veins keeps the water from freezing at the ambient permafrost temperature, creating
a habitable but very harsh environment. It is not the easiest place to survive,
but this organism is capable of remaining active to at least -25ºC
in permafrost.” says Lyle Whyte.
The researchers shared, this bacterium
is capable of surviving in permafrost and harsh cold conditions, however, such
microbes plays a big role in Global warming by releasing carbon dioxide from
the melting permafrost.

The P.halocryophilus bacterium tends to
bring increase in the amounts of cold-adapted proteins to survive in
permafrost. Prof. Whyte, who led the team of
researchers with Nadia Mykytczuk said, “"I'm kind of proud of this bug. It
comes from the Canadian High Arctic and is our cold temperature champion, but
what we can learn from this microbe may tell us a lot about how similar
microbial life may exist elsewhere in the solar system."
The results of this research were
shared to the common people some three months ago, to amaze everyone that at
least an Earthian, however a bacterium, is capable of surviving on the uneasy
and harsh subzero conditions of the Red Planet.
