Biology

Meanwhile, Earth-dwelling extremophile microorganisms, both thermophilic (heat-loving) and psychrophilic (cold-loving), are variously adapted to temperatures that would fry us or freeze us.
Example sentencesExamples
- In a refrigerator these organisms are repressed; instead, psychrophilic bacteria attack the milk protein and turn the milk alkaline and smelly.
- For psychrophilic fungi this can be achieved by reducing the air humidity and by preventing the formation of a water film on the canopy by using internal air circulation, heating or ventilation.

Origin

1920s: from Greek psukhros 'cold' + -phile.
