A novel thermophilic Gram-positive bacillus, “Bacillus thermoantarcticus”, isolated from geothermal soil near the crater of Mount Melbourne, is described. The organism grows at an optimal temperature of 63°C at pH 6.0, is oxidase-positive, catalase-negative and produces an exopolysaccharide, an exocellular xylanase, an intracellular alcohol dehydrogenase and exo- and endocellularα-glucosidase(s). The sequence of 16S rDNA is very similar to that of “Bacillus thermoglucosidasius”; however, the… 
Bacillus vulcani sp. nov., a novel thermophilic species isolated from a shallow marine hydrothermal vent.
A thermophilic spore-forming bacterium was isolated from sediment of a shallow hydrothermal vent at Vulcano Island (Italy). After phenotypic and molecular analyses, it was identified as a novel
Geobacillus gargensis sp. nov., a novel thermophile from a hot spring, and the reclassification of Bacillus vulcani as Geobacillus vulcani comb. nov.
The physiological, biochemical and DNA-DNA hybridization studies of strain Ga(T) showed that it differs both genotypically and phenotypically from the recognized Geobacillus species.
Extremophiles in Antarctica
The isolation of two new cyanobacteria and their polysaccharide characterization were described and the exopolysaccharides production and characterization, as well as thermophilic xylan‐degrading enzymes, were studied.
Alicyclobacillus pohliae sp. nov., a thermophilic, endospore-forming bacterium isolated from geothermal soil of the north-west slope of Mount Melbourne (Antarctica).
It is concluded that these isolates from a geothermal soil collected on the north-west slope of Mount Melbourne in Antarctica represent a novel species of the genus Alicyclobacillus, for which the name Alicy CLOBacillus pohliae sp.
Paenibacillus wynnii sp. nov., a novel species harbouring the nifH gene, isolated from Alexander Island, Antarctica.
Soil taken from 12 different locations at Mars Oasis on Alexander Island, Antarctica, yielded unidentified isolates of endospore-forming bacteria that represented a novel taxon of Paenibacillus wynnii sp.
Parageobacillus thermantarcticus, an Antarctic Cell Factory: From Crop Residue Valorization by Green Chemistry to Astrobiology Studies
Parageobacillus thermantarcticus strain M1 was isolated from geothermal soil of the crater of Mount Melbourne during the Italian Antarctic Expedition and the recent acquisition of its genome sequence opens up new opportunities for the use of this versatile bacterium in still unexplored biotechnology sectors.
Geobacillus subterraneus subsp. aromaticivorans subsp. nov., a novel thermophilic and alkaliphilic bacterium isolated from a hot spring in Sırnak, Turkey.
A new thermophilic spore-forming strain Ge1(T) was isolated from the Guclukonak hot spring in Sırnak, Turkey, and it is proposed that a novel subspecies of Geobacillus subterraneus is assigned, to be named as GeobACillus subterranus subsp.
Phylogenetic analysis of transformable strains of thermophilic Bacillus species.
It is concluded that the trait of transformability, though possibly strain-specific, is not limited to a single species of thermophilic Bacilli, and may be associated with a particular phylogenetic group.
Exopolysaccharide production by a new Halomonas strain CRSS isolated from saline lake Cape Russell in Antarctica growing on complex and defined media
A haloalkalophilic Halomonas strain CRSS, isolated from salt sediments in Antarctica, produced exocellularpolysaccharides (EPS) up to 2.9gg-1 dry cells and in presence of this substrate, a new polysaccharide, a fructo-glucan, was produced.
Compostibacillus humi gen. nov., sp. nov., a member of the family Bacillaceae, isolated from sludge compost.
The results of a polyphasic taxonomic study indicated that strains DX-3(T) and GIESS002 represent a novel species in a new genus in the family Bacillaceae, order Bacillales, for which the name Compostibacillus humi gen. nov. is proposed.


Bacillus thermoglucosidasius sp. nov., a New Species of Obligately Thermophilic Bacilli.
Isolation of five strains of thermophilic eubacteria in Antarctica
Five 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 and belong to the eubacterial domain.
16S rDNA analysis reveals phylogenetic diversity among the polysaccharolytic clostridia.
Lack of close genetic relationships between the various polysaccharolytic species is unexpected and may indicate that these biotechnologically important organisms differ with respect to the enzymology of polysaccholytic degradation as well.
A novel archaebacterial NAD+-dependent alcohol dehydrogenase. Purification and properties.
An NAD+-dependent alcohol dehydrogenase (alcohol: NAD+ oxidoreductase, EC 1.1.1) was detected in cellular extracts of the extreme thermophilic archaebacterium Sulfolobus solfataricus and appears to have some properties and a structure different from those previously described for thermophiles.
A thermostable acid α-glucosidase from Tetrahymena thermophila: purification and characterization
An acid alpha-glucosidase (EC was purified to homogeneity from the culture medium of Tetrahymena thermophila CU 399 and showed resistance to thermal inactivation and was antigenically distinct from T. pyriformis W enzyme.
Immobilized bacterial cells containing a thermostable β-galactosidase
A constitutive β-galactosidase has been localized in the cytosol of thermoacidophilic bacterium Caldariella acidophila and enzymic properties in entrapped cells are similar to those of the free enzyme.
