“…Although samples from hot vents with temperatures of more than 300°C have been analyzed (3,4), the maximal growth temperatures of the most extreme hyperthermophiles (organisms growing at and above 100°C) known, Pyrodictium occultum (12) and P. abyssum (Stetter, personal communication) do not exceed 110°C.…”

The hyperthermophilic peptide-fermenting sulfur archaebacterium Hyperthermus butylicus was isolated from the sea floor of a solfataric habitat with temperatures of up to 112°C on the coast of the island of Sao Miguel, Azores. The organism grows at up to 108°C, grows optimally between 95 and 106°C at 17 g of NaCl per liter and pH 7.0, utilizes peptide mixtures as carbon and energy sources, and forms H2S from elemental sulfur and molecular hydrogen as a growth-stimulating accessory energy source but not by sulfur respiration. The same fermentation products, C02, 1-butanol, acetic acid, phenylacetic acid, and a trace of hydroxyphenylacetic acid, are formed both with and without of So and H2. Its ether lipids, the absence of a mureine sacculus, the nature of the DNA-dependent RNA polymerase, and phylogenetic classification by DNA-rRNA cross-hybridization characterize H. butylicus as part of a novel genus of the major branch of archaebacteria comprising the orders Thermoproteales and Sulfolobales, representing a particularly long lineage bifurcating with the order Sulfolobales above the branching off of the genus Thermoproteus and distinct from the genera Desulfurococcus and Pyrodictium.Extremely thermophilic sulfur-reducing archaebacteria (13, 14) thrive either chemolithoautotrophically, utilizing CO2 as the sole carbon source and synthesis of H2S from SO and molecular hydrogen as the energy source, or by sulfur respiration of various organic carbon and energy sources.

“…Later this isolate provided the first archaeal genome that was fully sequenced (9). K Stetter's brilliant and prolific discoveries of highly diverse hyperthermophiles were partly done from deep-sea smoker samples or hot sediments collected during our diving cruises (10,20,30,31,80,102). Having him along or sending samples to him as well as to other colleagues was the best way to maximize the outcome of expensive ALVIN dives.…”

“…Those growing optimally at temperatures of more than 80 "C are called hyperthermophiles, and are usually unable to grow below 60 "C. The most extremely thermophilic species grow at temperatures between 80 and 110 "C and are strictly anaerobic archaea. Salt-dependent hyperthermophilic archaea of various genera have been isolated from shallow-water or deepsea submarine hydrothermal areas (Fiala et al, 1986;Kurr et al, 1991;Miroschnichenko et al, 1989;Neuner et al, 1990;Pledger & Baross, 1989Pley et al, 1991). The genus Thermotoga includes the most thermophilic members of Bacteria, which may grow in environments up to 90 "C .…”

A heterotrophic, moderately thermophilic bacterial strain, designated strain T501, was isolated from a hot spring on the coast of Lutao, Taiwan. This bacterial strain was a strictly aerobic, Gram-negative rod, normally 0 . 6 4 7 pm in diameter and 4-10 pm in length, and motility was achieved by one to several lateral flagella. Its minimum and maximum growth temperatures were approximately 30 and 60 "C, respectively, with an optimal temperature at about 50 "C. The G + C ratio of its DNA was 38.1 mol%. Strain T501 tolerated a pH range from 6 to 9. It was halophilic, growing optimally in about 2 % (w/v) salt, and Na+ was indispensable unless Mg2+ or Ca2+ were available. The addition of either cation to Na+-sufficient media significantly enhanced growth. Halophilic heterotrophic bacteria capable of aerobic growth over a temperature range of 4&55 "C have not been reported previously.
