WebPsychrophile. Psychrophiles or Cryophiles (adj. cryophilic) are extremophilic organisms that are capable of growth and reproduction in cold temperatures. They can be contrasted with thermophiles, which thrive at unusually hot temperatures. The environments they inhabit are ubiquitous on Earth, as a large fraction of our planetary surface ... WebThe source material for these bacteria were from fish, natural waters, foods, wastes, rubbish, soil surface, and intestines of fish. The lowest temperature at which bacteria can grow remains to be determined definitely and −12°C is the lowest temperature reported. The term “psychrophile” was first used in 1902 by Schmidt-Nielsen.
