Planococcus halocryophilus



Planococcus halocryophilus is an aerobic, gram-positive bacterium that is found in arctic permafrost. This extremophile is characterized as both halophilic and psychrophilic, thriving in an environment of high salinity as well as an extremely low temperature. This bacterium's reproduction capability is measured at the lowest recorded temperature, measured at -15ºC. Planococcus halocryophilus continues to preserve itself at temperatures as low as -25ºC. The bacterium is accountable for effects of global warming, bringing about sizable CO2 emissions concurrent to melting permafrost. Astrobiological research towards this extremophile is resonant owing to its similitude of potential target environments for life on Mars.
