Extremophiles (but in flashcards)

I wonder what its about

Acidophile

An organism with optimal growth at pH levels of 3.0 or below

Alkaliphile

An organism with optimal growth at pH levels of 9.0 or above

Acidophile

An organism with optimal growth at pH levels of 3.0 or below

Alkaliphile

An organism with optimal growth at pH levels of 9.0 or above

Anaerobe

An organism with optimal growth in the absence of molecular oxygen.

Capnophile

An organism with optimal growth in high concentrations of carbon dioxide.

Cryptoendolith

An organism that lives in microscopic spaces, such as pores between aggregate grains.

Halophile

An organism with optimal growth at a concentration of dissolved salts of 50g/L (5% concentration) or above.

Hyperpiezophile

An organism with optimal growth at hydrostatic pressures above 50 MPa (= 493 atm = 7,252 psi).

Hyperthermophile

An organism with optimal growth at temperatures above 80 °C (176 °F).

Hypolith

An organism that lives underneath rocks in cold deserts.

Metallotolerant

Capable of tolerating high levels of dissolved heavy metals in solution, such as copper, cadmium, arsenic, and zinc.

Oligotroph

An organism with optimal growth in nutritionally limited environments.

Osmophile

An organism with optimal growth in environments with a high sugar concentration.

Piezophile

An organism with optimal growth in hydrostatic pressures above 10 MPa (= 99 atm = 1,450 psi). Also referred to as barophile.

Polyextremophile

An organism that qualifies as an extremophile under more than one category.

Psychrophile/Cryophile

An organism with optimal growth at temperatures of 15 °C (59 °F) or lower.

Radioresistant

Organisms resistant to high levels of ionizing radiation, most commonly ultraviolet radiation. This category also includes organisms capable of resisting nuclear radiation.

Sulphophile

An organism with optimal growth conditions in high concentrations of sulfur.

Thermophile

An organism with optimal growth at temperatures above 45 °C (113 °F).

Xerophile

An organism with optimal growth at water activity below 0.8.
