WebApr 16, 2007 · Abstract. Psychrophiles are extremophilic bacteria or archaea which are cold-loving, having an optimal temperature for growth at about 15°C or lower, a maximal temperature for growth at about 20°C and a minimal temperature for growth at 0°C or lower. Psychrotrophs are cold-tolerant bacteria or archaea that have the ability to grow at low ... The cold environments that psychrophiles inhabit are ubiquitous on Earth, as a large fraction of the planetary surface experiences temperatures lower than 10 °C. They are present in permafrost, polar ice, glaciers, snowfields and deep ocean waters. These organisms can also be found in pockets of sea ice with high salinity content. Microbial activity has been measured in soils frozen below −3…
