''Pyrobaculum aerophilum'' is a single-celled microorganism in the genus ''Pyrobaculum''. The first ''Pyrobaculum'' species to be sequenced was ''P. aerophilum''. It is a rod-shaped
hyperthermophilic
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). Hyperthermophiles are often within the doma ...

Pyrobaculum
''Pyrobaculum'' is a genus of the Thermoproteaceae.
Description and significance
As its Latin name ''Pyrobaculum'' (the "fire stick") suggests, the archaeon is rod-shaped and isolated from locations with high temperatures. It is Gram-negative ...

The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
The boiling point of a liquid varies depending upon the surrounding envir ...

Its optimum pH for growth is 7.0. Sulfur was found to inhibit its growth.
Its circular genome sequence is 2,222,430

Whole genome analysis demonstrated that it lacks 5' untranslated regions in its mRNAs. This implies that it does not employ the
Shine-Delgarno sequence to initiate protein synthesis.
