Crenarchaeota

Crenarchaeota exist in a wide range of habitats and exhibit a great variety of chemical reactions in their metabolism.

A hyperthermophile thrives at relatively high temperatures and can be found in geothermally heated regions of the Earth.

Hyperthermophiles live in dark regions of the oceans and use chemosynthesis to produce biomass from single carbon molecules.

Nonthermophilic Crenarchaeota can be extreme halophiles living in highly salty environments.

Psychrophiles crenarchaeotes are extremophilic organisms that are capable of growth and reproduction in cold temperatures.
