A novel moderately thermophilic, heterotrophic bacterium was isolated from a deep-sea hydrothermal vent deposit from the Mariner field along the Eastern Lau Spreading Center of the south-western Pacific Ocean. Cells were short motile rods (about 0.4×0.8 µm) that occurred singly or in pairs and were surrounded by a sheath-like membrane or 'toga'. The cells grew between 45 and 65 °C (optimum 57-60 °C) and at pH 4.1-6.0 (optimum pH 5.5-5.7) and grew optimally at 3 % (w/v) NaCl. The isolate grew on…

Athalassotoga saccharophila gen. nov., sp. nov., isolated from an acidic terrestrial hot spring, and proposal of Mesoaciditogales ord. nov. and Mesoaciditogaceae fam. nov. in the phylum Thermotogae.

The isolate from a low-salt acidic terrestrial hot spring in Oku-Shiobara, Tochigi, Japan, represents a novel species of a new genus in the phylum Thermotogae, for which the name Athalassotoga saccharophila gen. nov. is proposed.

Methanocaldococcus lauensis sp. nov., a novel deep-sea hydrothermal vent hyperthermophilic methanogen

It is proposed that strains SG1 andSG7T are representatives of a novel species, for which the name Methanocaldococcus lauensis sp.

Fervidobacterium thailandense sp. nov., an extremely thermophilic bacterium isolated from a hot spring.

Phylogenetic analysis of 16S rRNA gene sequences and average nucleotide identity analysis suggested that strain FC2004T represented a novel species within the genus Fervidobacterium, for which the name Fervidia thailandense sp.

Complete genome sequence and whole-genome phylogeny of Kosmotoga pacifica type strain SLHLJ1T from an East Pacific hydrothermal sediment

The percentage of conserved proteins (POCP), which is much higher than 50% (around 70%), together with phenotypic features of the isolates, confirm the affiliation all Kosmotoga species described so far to the same genus.

Genomic analysis of the mesophilic Thermotogae genus Mesotoga reveals phylogeographic structure and genomic determinants of its distinct metabolism

This study comprises one of the first whole-genome-based phylogeographic analyses of anaerobic mesophiles, and data suggest that such microbes are more restricted by geography than are thermophiles (and mesophilic aerobes).

Prokaryotic diversity across a pH gradient in the “El Chichón” crater-lake: a naturally thermo-acidic environment

The "El Chichón" crater-lake in Mexico is a thermo-acidic environment whose microorganisms have been scarcely studied. In this study, we surveyed the prokaryotic communities by amplicon sequencing of

Prokaryotic diversity across a pH gradient in the “El Chichón” crater-lake: a naturally thermo-acidic environment

The results show the presence of a microbial community adapted to the changing conditions of a very dynamic crater-lake, that include chemoorganotrophs and chemolithotrophy, that mainly occur in the most extreme sites of the lake.
