Temperature range for psychrophiles
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… WebPsychrophilic ("cold loving") microorganisms , particularly bacteria , have a preferential temperature for growth at less than 59 ° Fahrenheit (15 ° Celsius). Bacteria that can grow at such cold temperatures, but which prefer a high growth temperature, are known as psychrotrophs. The discovery of psychrophilic microorganisms and the ...
