psychrophile
Quick Summary
A psychrophile is a microorganism that thrives at relatively low temperatures. These organisms are distinct from thermophiles, which prefer hot temperatures, and mesophiles, which prefer moderate temperatures.12
Microorganisms, including psychrophiles, exhibit a wide range of nutritional requirements and grow under diverse environmental conditions. While some microorganisms can grow in simple inorganic salt solutions, others require more complex nutrients like amino acids and vitamins.3
Psychrophiles are often found in environments such as sea ice and open waters. Some archaea, a domain of prokaryotic organisms, are extremophiles that can survive in extreme temperatures, with some thriving above 100°C (212°F). However, archaea are also found in cold and temperate ecosystems, playing important ecological roles.234
