A hyperthermophile is an organism that thrives in extremely hot environments—from 60 °C (140 °F) upwards. An optimal temperature for the existence of hyperthermophiles is often above 80 °C (176 °F). [1] Hyperthermophiles are often within the domain Archaea, although some bacteria are also able to
P. fumarii is a hyperthermophile, indicating that this organism grows best at extremely high temperatures (70–125 °C). P. fumarii grows best at 106 °C. Due to the extremely high temperatures this archaea is subjected to, this organism must have extremely stable biomolecules to survive.
Pyrococcus furiosus is a heterotrophic, strictly anaerobic, extremophilic, model species of archaea.It is classified as a hyperthermophile because it thrives best under extremely high temperatures, and is notable for having an optimum growth temperature of 100 °C (a temperature that would destroy most living organisms). [1]
Pyrolobus fumarii (Latin for "fire lobe of the chimney" [1]) is a species of archaea known for living and reproducing at extremely high temperatures that kill most organisms. [1] [2] P. fumarii is known as a hyperthermophile obligately chemolithoautotroph. In the simplest terms, this archaea grows best in warm temperatures ranging from 80 °C ...
Thermococcus litoralis (T. litoralis) is a species of Archaea that is found around deep-sea hydrothermal vents as well as shallow submarine thermal springs and oil wells. [2] [3] [4] It is an anaerobic organotroph hyperthermophile that is between 0.5–3.0 μm (20–118 μin) in diameter. [2]
Many hyperthermophilic Archaea require elemental sulfur for growth. Some are anaerobes that use the sulfur instead of oxygen as an electron acceptor during cellular respiration (anaerobic) . Some are lithotrophs that oxidize sulphur to create sulfuric acid as an energy source, thus requiring the microorganism to be adapted to very low pH (i.e ...
Pyrococcus abyssi is a hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent in the North Fiji Basin at 2,000 metres (6,600 ft). It is anaerobic, sulfur-metabolizing, gram-negative, coccus-shaped and highly motile.
In taxonomy, Thermococcus is a genus of thermophilic Archaea in the family the Thermococcaceae. [1] Members of the genus Thermococcus are typically irregularly shaped coccoid species, ranging in size from 0.6 to 2.0 μm in diameter. [2] Some species of Thermococcus are immobile, and some species have motility, using flagella as their main mode ...
