“…The presence of MK-8 as the predominant respiratory quinone is consistent with reports of MK-8 in members of the genera Thermus, Meiothermus, Marinithermus and Oceanithermus (Hensel et al, 1986;Chung et al, 1997;Sako et al, 2003;Miroshnichenko et al, 2003b). The presence of iso-and anteiso-branched fatty acids is a feature of members of these genera and also Deinococcus (Embley et al, 1987;Ferreira et al, 1997;Donato et al, 1990Donato et al, , 1991Sako et al, 2003;Miroshnichenko et al, 2003b).…”

“…However, reports have now shown that ecological niches for thermophilic aerobes could exist in this habitat (Marteinsson et al, 1995(Marteinsson et al, , 1996(Marteinsson et al, , 1999Sako et al, 2003, Miroshnichenko et al, 2003b.

“…All representatives of the family Thermaceae isolated to date from shallow-water hot vents are halotolerant, growing optimally in the absence of NaCl (da Costa & Rainey, 2001). The only obligately marine representatives of this group, Marinithermus hydrothermalis (Sako et al, 2003) and Oceanithermus profundus (Miroshnichenko et al, 2003b), were isolated very recently from the deep-sea hydrothermal environment. In this paper, we describe a novel member of the family Thermaceae, recovered from an in situ collector deployed on a hydrothermal vent of the Mid-Atlantic Ridge, that is also obligately dependent on a salinity equivalent to that of sea water.…”

Vulcanithermus mediatlanticus gen. nov., sp. nov., a novel member of the family Thermaceae from a deep-sea hot vent A novel thermophilic, microaerophilic, facultatively chemolithoheterotrophic bacterium designated strain TR T was isolated from a sample of a deep-sea hydrothermal chimney collected at the Rainbow vent field on the Mid-Atlantic Ridge (36˚149N). Gram-negative, non-spore-forming, non-motile rods occurred singly or in pairs. The organism grew in the temperature range 37-80˚C with an optimum at 70˚C and at pH 5?5-8?4 with an optimum around 6?7. The NaCl range for growth was 10-50 g l "1 with an optimum of 30 g l "1 . Strain TR T grew chemoorganoheterotrophically with carbohydrates, proteinaceous substrates, organic acids and alcohols using oxygen or nitrate as electron acceptors. The isolate was able to grow at oxygen concentrations from 0?5 to 21 %. Oxygen concentrations that promoted fastest growth ranged from 4 to 8 % under agitation. The novel isolate was able to grow lithoheterotrophically with molecular hydrogen as the energy source. The G+C content of the genomic DNA was 68?4 mol%. Phylogenetic analysis of the 16S rDNA sequence placed strain TR T within the phylum Deinococcus-Thermus of the Bacteria. On the basis of phenotypic and phylogenetic data, it is proposed that this isolate should be described as a member of a novel species of a new genus as Vulcanithermus mediatlanticus gen. nov., sp. nov. The type strain is

Spermidine and a quaternary branched penta-amine, N 4 -bis(aminopropyl)norspermidine, were the major polyamine in Thermocrinis, Hydrogenobacter, Hydrogenobaculum, Aquifex, Persephonella, Sulfurihydrogenibium, Hydrogenothermus, Balnearium and Thermovibrio, located in the order Aquificales. Thermodesulfobacterium and Thermodesulfatator belonging to the order Thermodesulfobacteriales contained another quaternary penta-amine, N 4 -bis(aminopropyl)spermidine. In the order Thermotogales, Thermotoga contained spermidine, norspermidine, caldopentamine and homocaldopentamine. The latter two linear penta-amines were not found in Marinitoga and Petrotoga. In the order Thermales, Thermus and Marinithermus contained homospermidine, norspermine and the linear penta-amines. Meiothermus lacked penta-amines. Vulcanithermus contained linear penta-amines and hexa-amines but not homospermidine. Oceanithermus contained spermine alone. Within the order Thermoanaerobacteriales, the two quaternary branched penta-amines were found in Thermanaeromonas and Thermoanaerobacter. Caldanaerobacter contained N 4 -bis(aminopropyl)spermidine. Thermoanaerobacterium lacked penta-amines. Thermaerobacter of the order Clostridiales contained N 4 -bis(aminopropyl)spermidine and agmatine. Thermosyntropha, Thermanaerovibrio, Thermobrachium (the order Clostridiales), Sulfobacillus, Alicyclobacillus, Anoxybacillus, Ureibacillus, Thermicanus (the order Bacillales), Desulfotomaculum, Desulfitobacterium and Pelotomaculum (the family Peptococcaceae) ubiquitously contained spermine. Some thermophiles of Bacillales added linear and branched penta-amines.

The Deinococcus–Thermus group represents an ancient lineage that contains some of the most conspicuous species within the domain Bacteria . The group is distinguished by species that resist the lethal effects of exposure to ionising radiation and ultraviolet light, and by species that thrive at high temperature. Deinococcus–Thermus is comprised of two orders, the Deinococcales and the Thermales . The mostly mesophilic species of Deinococcales demonstrate uncommon resistance following exposure to electromagnetic radiations, tolerating doses that normally destroy vegetative bacteria. The Thermales are thermophilic with optimal growth at temperatures between 60 and 80 °C, but show no evidence of resistance to electromagnetic radiation. Despite these striking and distinctive phenotypic differences, 16S ribosomal ribonucleic acid sequences verify that members of these orders are specifically related to each other. Key Concepts Species within the Deinococcus–Thermus group exist over a wide geographic distribution within the natural and built environments. All species within the Deinococcus–Thermus group are specifically related to each other through their 16S rRNA sequences. Members of the Deinococcales and Thermales share only three phenotypic characteristics: all are nonmotile, none form endospores and all utilise menaquinone 8 as their major respiratory lipoquinone. Members of the Deinococcales are aerobic, chemoorganotrophic and display respiratory metabolism. Other chemotaxonomic characteristics of this order are more varied than might be expected for closely related species. Most members of the Deinococcales display extreme resistance to the lethal effects of ionising radiation and UV light; there is a subset of species that are substantially less resistant to these agents. Members of the Thermales are thermophilic or slightly thermophilic rods. Optimal growth temperature for the type strains within the order falls between 60 and 70 °C, but there is considerable variation in growth temperature among nontype species. Most members of the Thermales are aerobic chemoorganotrophs reported to grow between pH 5.0 and 10.5 with optimal growth between pH 6 and 7. In the presence of an appropriate electron acceptor, some species will grow anaerobically. Members of the Thermales are routinely isolated from hydrothermal features worldwide at freshwater and marine sites, including deep sea hydrothermal vents.
