Web4 Psychrophiles were first reported at 1884, but most of the early literature dealt with psychrotrophic bacteria. Since scientists were not able to work with extreme cold-loving Bacteria there were a lot of debate about the psychrophiles. Many scientists also confused the term Psychrophiles with: Cryophile, rhigophile, psychrorobe, thermophobic ... Psychrophiles or cryophiles (adj. psychrophilic or cryophilic) are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from −20 °C (−4 °F) to 20 °C (68 °F) . They have an optimal growth temperature at 15 °C (59 °F). They are found in places that are permanently cold, … See more Habitat 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 See more Psychrotrophic microbes are able to grow at temperatures below 7 °C (44.6 °F), but have better growth rates at higher temperatures. Psychrotrophic bacteria and fungi are able to … See more Insects that are psychrotrophic can survive cold temperatures through several general mechanisms (unlike opportunistic and chill susceptible insects): (1) chill tolerance, (2) freeze avoidance, and (3) freeze tolerance.
