Journal ArticleDOI
Pyrococcus furiosus sp. nov. represents a novel genus of marine heterotrophic archaebacteria growing optimally at 100°C
Gerhard Fiala,Karl O. Stetter +1 more
TL;DR: Ten strains representing a novel genus of marine thermophilic archaebacteria growing at between 70 and 103°C with an optimal growth temperature of 100°C and a doubling time of only 37 min were isolated from geothermally heated marine sediments at the beach of Porto di Levante, Vulcano, Italy.
Journal ArticleDOI
A new phylum of Archaea represented by a nanosized hyperthermophilic symbiont
Harald Huber,Michael J. Hohn,Reinhard Rachel,Tanja Fuchs,Tanja Fuchs,Verena C. Wimmer,Karl O. Stetter +6 more
TL;DR: The cultivation of a new nanosized hyperthermophilic archaeon from a submarine hot vent is reported, which will provide insight into the evolution of thermophily, of tiny genomes and of interspecies communication.
Journal ArticleDOI
Thermotoga maritima sp. nov. represents a new genus of unique extremely thermophilic eubacteria growing up to 90°C
Robert Huber,Thomas A. Langworthy,Helmut König,Michael Thomm,Carl R. Woese,Uwe B. Sleytr,Karl O. Stetter +6 more
TL;DR: A novel type of bacterium has been isolated from various geothermally heated locales on the sea floor with a unique sheath-like structure and monotrichous flagellation that clearly belong to the eubacteria, although no close relationship to any known group could be detected.
Journal ArticleDOI
The genome of Nanoarchaeum equitans: Insights into early archaeal evolution and derived parasitism
Elizabeth M. Waters,Michael J. Hohn,Ivan Ahel,David E. Graham,Mark Raymond Adams,Mary Barnstead,Karen Beeson,Lisa Bibbs,Randall Bolanos,Martin Keller,Keith A. Kretz,Xiaoying Lin,Eric J. Mathur,Jingwei Ni,Mircea Podar,Toby Richardson,Granger G. Sutton,Melvin I. Simon,Dieter Söll,Karl O. Stetter,Jay M. Short,Michiel Noordewier +21 more
TL;DR: The hyperthermophile Nanoarchaeum equitans is an obligate symbiont growing in coculture with the crenarchaeon Ignicoccus, and represents a basal archaeal lineage and has a highly reduced genome.
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").
