The first Pyrobaculum species to be sequenced was P. aerophilum. It is a rod-shaped hyperthermophilic archaeum first isolated from a boiling marine water hole at Maronti Beach, Ischia. It forms characteristic terminal spherical bodies (so called "golf clubs") like Thermoproteus and Pyrobaculum. Its type strain is IM2; DSM 7523).[1] Its optimum temperature for growth is around boiling point for water.[1] Its optimum pH for growth is 7.0. Sulfur was found to inhibit its growth.[1] Its circular genome sequence is 2,222,430 Bp in length and contains 2605 protein-coding sequences (CDS). It is capable of aerobic respiration. Its name references this ability: aerophilum coming from the Greek: ἀήρ ("aero"), meaning air, and φιλο (philo), meaning loving. It produces colonies that are round and greyish yellow. It uses both organic and inorganic compounds during respiration.[2][3] 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.[4] References1. ^{{cite journal|display-authors=4 |last1=Ausili |first1=Alessio |last2=Vitale |first2=Annalisa |last3=Labella|first3=Tullio|last4=Rosso|first4=Francesco|last5=Barbarisi|first5=Alfonso|last6=Gómez-Fernández|first6=Juan C. |last7=D’Auria|first7=Sabato|title=Alcohol dehydrogenase from the hyperthermophilic archaeon Pyrobaculum aerophilum: Stability at high temperature|journal=Archives of Biochemistry and Biophysics|volume=525|issue=1|date=2012|pages=40–46|issn=0003-9861 |doi=10.1016/j.abb.2012.05.019 |pmid=22683471}} 2. ^1 2 {{cite journal |author=Völkl P |author2=Huber R |author3=Drobner E|display-authors=etal |title=Pyrobaculum aerophilum sp. nov., a novel nitrate-reducing hyperthermophilic archaeum |journal=Applied and Environmental Microbiology |volume=59 |issue=9 |pages=2918–26 |date=September 1993 |pmid=7692819 |pmc=182387 |doi= |url=http://aem.asm.org/cgi/pmidlookup?view=long&pmid=7692819 |issn= |accessdate=2013-07-25}} 3. ^{{cite journal |display-authors=4|last1=Cozen|first1=A.
