What is a cryophile habitat?

Psychrophiles or cryophiles (adj. psychrophilic or cryophilic) are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from −20 °C to +10 °C. They are found in places that are permanently cold, such as the polar regions and the deep sea.

How do Cryophile adapted to their environment?

Antifreeze proteins basically help a psychrophiles to live in colder temperatures by lowering the average temperature it could live in, drastically. This is very important in cryoprotection, which is the protection of cryophiles from denaturing in its cold temperature.

Where do you find Psychrophiles in nature?

Each microorganism has a temperature range over which it can grow. Psychrophiles grow best at temperatures < 15 °C. In nature, they are commonly found in deep ocean waters or in polar regions. Mesophiles, which grow between 15 and 45 °C, are the most common types of microorganisms and include most pathogenic species.

How do Psychrophiles survive in their environment?

To survive at temperatures close to the freezing point of water, psychrophiles have evolved some important cellular adaptations, including mechanisms to maintain membrane fluidity [[3, 4]], synthesis of cold-acclimation proteins [[5]], freeze tolerance strategies [[6]], and cold-active enzymes.

What are Psychrophilic organisms?

Psychrophilic bacteria are defined as cold-loving bacteria. ... The psychrotrophs are cold-tolerant bacteria, but their maximal growth temperature ranges above 20 °C and in many cases their optimal growth temperature is also above 20 °C. A better term for these organisms that withstand cold temperatures is psychrotolerant.

Where are Piezophile found?

Piezophiles are known among vertebrates and invertebrates but prokaryotic piezophiles (Bacteria and Archaea) are the most extensively studied. They live in various habitats that are exposed to elevated hydrostatic pressure (deep aquifers, deep oil reservoirs, etc.), but the best known are from the deep ocean floor.

Where do Hyperthermophiles live?

The most extreme hyperthermophiles live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90 °C for survival.

Which environment would harbor Psychrophiles?

Psychrophiles are microorganisms that can grow at 0 °C and below, have an optimum growth temperature close to 15 °C, and usually do not survive at temperatures above 20 °C. They are found in permanently cold environments such as the deep waters of the oceans.

Where did scientists find Psychrophiles deep in a frozen lake?

Microbes, some of which may be viable, have been found in ice cores drilled at Vostok Station at depths down to ≈3,600 m, close to the surface of the huge subglacial Lake Vostok.

What are some examples of Psychrotrophs?

Psychrotrophic bacteria grow at less than 7°C. Common species in cold stored milk, which is the storage norm in most jurisdictions, are Micrococcus, Bacillus, Staphylococcus, Pseudomonas, Flavobacterium, and coliforms. Pseudomonas spp. are the most common and typically have the greatest impact on quality.

Are psychrophiles Autotrophs or Heterotrophs?

Thus, psychrophiles are autotrophic or heterotrophic, aerobic or anaerobic, spore-formers and nonspore-formers, phototrophs and nonphototrophs.

How does thermophiles and psychrophiles affect the life of microorganisms?

Because they are active at low temperature, psychrophiles and psychrotrophs are important decomposers in cold climates. Organisms that grow at optimum temperatures of 50 °C to a maximum of 80 °C are called thermophiles (“heat loving”). They do not multiply at room temperature.

Where would you find a Mesophile?

Mesophiles are microorganisms which grow at moderate temperatures between 20 °C and 45 °C and with an optimum growth temperature in the range of 30–39 °C. They are isolated in both soil and water environments; species are found in the Bacteria, Eukarya, and Archaea kingdom.

What is a Mesophile in microbiology?

A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, typically between 20 and 45 °C (68 and 113 °F). The term is mainly applied to microorganisms. All bacteria have their own optimum environmental surroundings and temperatures in which they thrive the most.

Is E coli a Mesophile?

We have investigated the growth of Escherichia coli, a mesophilic bacterium, as a function of pressure (P) and temperature (T). Escherichia coli can grow and divide in a wide range of pressure (1–400 atm) and temperature (23–40°C). ... coli at high pressures where bacterial cells switch to an elongating cell type.
