Journal ArticleDOI
Pyrolobus fumarii, gen. and sp. nov., represents a novel group of archaea, extending the upper temperature limit for life to 113 degrees C
E. Blöchl,Reinhard Rachel,Siegfried Burggraf,Doris Hafenbradl,Holger W. Jannasch,Karl O. Stetter +5 more
TL;DR: A novel, irregular, coccoid-shaped archaeum was isolated from a hydrothermally heated black smoker wall at the TAG site at the Mid Atlantic Ridge and described here a new genus, which is named Pyrolobus (the "fire lobe").
Journal ArticleDOI
Ferroglobus placidus gen. nov., sp. nov., a novel hyperthermophilic archaeum that oxidizes Fe2+ at neutral pH under anoxic conditions
Doris Hafenbradl,Martin Keller,Reinhard Dirmeier,Reinhard Rachel,P. Rossnagel,Siegfried Burggraf,Harald Huber,Karl O. Stetter +7 more
TL;DR: A novel coccoid, anaerobic, Fe2+-oxidizing archaeum was isolated from a shallow submarine hydrothermal system at Vulcano, Italy and represents a novel genus among the Archaeoglobales that is named Ferroglobus.
Journal ArticleDOI
Thermococcus alcaliphilus sp. nov., a new hyperthermophilic archaeum growing on polysulfide at alkaline pH
Martin Keller,Franz-Josef Braun,Reinhard Dirmeier,Doris Hafenbradl,Siegfried Burggraf,Reinhard Rachel,Karl O. Stetter +6 more
TL;DR: A novel coccoid-shaped, hyperthermophilic, heterotrophic member of the archaea was isolated from a shallow marine hydrothermal system at Vulcano Island, Italy and is namedThermococcus alcaliphilus.
Journal ArticleDOI
Pathways of autotrophic CO2 fixation and of dissimilatory nitrate reduction to N2O in Ferroglobus placidus
TL;DR: From the enzyme and coenzyme composition of the cells, it was deduced that autotrophic CO2 fixation in F. placidus proceeds via the carbon monoxide dehydrogenase pathway as in autotrophically growing Archaeoglobus and Methanoarchaea species.

TL;DR: The phylum currently consists of seven classes: the Methanobacteria, the methanococci, the Halob bacteria, the Thermoplasmata, the thermophilic S0 metabolizers,The Euryarchaeota are morphologically diverse and occur as rods, cocCI, irregular cocci, lancet-shaped, spiral- shaped, disk-shaped or triangular, or square cells.
