SummaryFive isolates of thermophilic bacteria, capable of growing at 65°C, were obtained from samples of soil collected from the Cryptogam Ridge (Mount Melbourne) and in the area north of Edmonson Point, Northern Victoria Land, Antarctica. Electron microscopy, morphological and physiological properties, lipid analyses and GC content of the isolates are described in this paper. On the basis of the results presented the organisms belong to the eubacterial domain. 
“Bacillus thermoantarcticus” sp. nov., from Mount Melbourne, Antarctica: a novel thermophilic species
TLDR
A novel thermophilic Gram-positive bacillus, isolated from geothermal soil near the crater of Mount Melbourne, is described and the sequence of 16S rDNA is very similar to that of “Bacillus thermoglucosidasius”; however, the guanine-plus-cytosine (G + C) content is 8 mol% higher.
Characterization of Culturable Thermophilic Actinobacteria from Livingston Island, Antarctica
TLDR
It is found that all strains are sensitive to eight, and 77% to ten of the 12 tested antibiotics suggesting relatively low anthropogenic impact in this Antarctic region.
Iron Demand by Thermophilic and Mesophilic Bacteria Isolated from an Antarctic Geothermal Soil
TLDR
The results suggest a possible involvement of the thermophilic strain MP4 in iron bioavailability in these geothermal soils.
Brevibacillus levickii sp. nov. and Aneurinibacillus terranovensis sp. nov., two novel thermoacidophiles isolated from geothermal soils of northern Victoria Land, Antarctica.
TLDR
Preliminary metabolic studies revealed that L-glutamic acid, although not essential for growth, was utilized by both species and was 20-fold greater than that shown by the Aneurinibacillus species type strain.
The frequency and characteristics of highly thermophilic bacteria in cool soil environments.
TLDR
Biochemical testing of five strains reveals a significant ability to utilize alkanes and some aromatic hydrocarbons and the question is raised of how these organisms, which are apparently unable to grow at the temperatures experienced in these cool soils, are so prominent.
Microbial Communities Present in Hydrothermal Sediments from Deception Island, Antarctica
TLDR
A multidisciplinary study about sediments obtained by deposition during 4 years in Antarctica, revealing a high influence of the physicochemical conditions in the microbial populations and their distribution, offering valuable data on the interaction between the island and water microbiota.
The Genus Geobacillus
kaustophilus stearothermophilus subterraneus terreneus thermosphaericus halophilus badius cereus subtilis halotolerans marismortui salexigens laterosporus agri brevis macerans polymyxa popilliae
New record of moss and thermophilic bacteria species and physico-chemical properties of geothermal soils on the northwest slope of Mt. Melbourne (Antarctica)
TLDR
It was concluded that physico-chemical features of geothermal grounds may affect the colonisation history and dispersal of microorganisms and mosses.
Microbial biodiversity of thermophilic communities in hot mineral soils of Tramway Ridge, Mount Erebus, Antarctica.
TLDR
The hypotheses that Tramway Ridge organisms are relics of archaic microbial lineages specifically adapted to survive in this harsh environment and that this site may provide a portal to the deep-subsurface biosphere are reinvigorated.
Microbial Ecology of Geothermal Habitats in Antarctica
TLDR
The application of molecular strategies promises to revolutionize the current understanding of geothermal habitats at Deception Island and reveal the presence of potentially endemic organisms that previously escaped detection.

Enumeration of Thermophilic Heterotrophs in Geothermally Heated Soils from Mount Erebus, Ross Island, Antarctica
TLDR
Soil samples with temperatures up to 64 degrees C were collected from Mount Erebus, an active volcano located on Ross Island, Antarctica, and showed a wide variation in the number of thermophilic microorganisms in different soils.
Isolation of a strain of Bacillus schlegelii from geothermally heated antarctic soil
TLDR
A bacterium capable of growth from 59 to 72° C was isolated from geothermal soil collected from Mount Erebus, Ross Island, Antarctica and had a characteristic subunit layer on the cell wall which is typical of B. schlegelii.

Archaebacteria: Lipids, Membrane Structures, and Adaptation to Environmental Stresses
TLDR
In the past few years a revolution has occurred in the taxonomy of living organisms, and organisms are no longer merely gathered into two groups of eubacteria and eukaryotes, but may be considered to belong to a third line, the archaebacteria.
Bacillus tusciae, a new species of thermoacidophilic, facultatively chemolithoautotrophic hydrogen oxidizing sporeformer from a geothermal area
TLDR
Based on its morphological and biochemical features, the organism belongs to the genus Bacillus, but differs from all the previously described species, and is proposed as constituting a new species, Bacillus tusciae.
Insensitivity of archaebacterial ribosomes to protein synthesis inhibitors. Evolutionary implications.
TLDR
Through comparison with suitable eubacterial and eukaryotic cell‐free systems the insensitivity of Sulfolobus ribosomes to most inhibitors of protein synthesis appears to reflect a phylogenetic distinction of ribosome structure, rather than the high temperature conditions of the Sulfoobus assay system.
