Aeropyrum pernix is a species of extremophile archaea in the archaeal phylum Thermoproteota. It is an obligatorily thermophilic species. The first specimens were isolated from sediments in the sea off the coast of Japan.

Properties
The cells of Aeropyrum pernix are spherical in shape and approximately 1 μm in diameter. The envelope surrounding the cells of Aeropyrum is about 25 nm wide. The organisms grows at temperature between 70 and 100 °C (optimum, 90 to 95 °C), at pH 5 to 9 (optimum, pH 7), and at a salinity of 1.8 to 7% (optimum, 3.5% salinity). The growth of the organisms is not detected at 68 or 102 °C. Below 1.5% salinity, cells lyse by low osmotic shock. The cells of the organisms are sensitive to chloramphenicol and insensitive to ampicillin, vancomycin, and cycloserine. It grows well on proteinaceous substances, with a doubling time under these conditions of about 200 minutes.[1] This species lacks the genes for purine nucleotide biosynthesis and thus relies on environmental sources to meet its purine requirements.[3]
