Aciduliprofundum is a genus of the Euryarchaeota.
[1] A. boonei, is an extremophile, a thermoacidophilic archaeon that lives in oceanic deep-sea hydrothermal vents, that has been shown to produce antibiotics against common pathogenic bacteria.
[2] It is one of a group of euryarchaeotes classed as DHVE2 – Deep-Sea Hydrothermal Vent Euryarchaeota 2, and the only one to be isolated.
[3] It is extremely widespread and yet has not been able to be cultivated.
[4] For this reason it may sometimes have the taxonomic addition of Candidatus to its name - meaning a candidate for, until proven.
