Physiologically diverse group of Archaea Extreme halophilic Archaea
Many inhabit extreme environments like
high temperatures, high salt, high acid Methanogenic Archaea
Nanoarchaeota and Thermoplasmatales
the "Hospitable Fireball" Thermococcales & Methanopyrus
Archaeoglobales
Thaumarchaeota and
nitrification in Archaea
Habitats and energy metabolism
of Crenarchaeota
Korarchaeota and
the "Secret Filament" Crenarchaeota from Terrestrial
Volcanic Habitats
Crenarchaeota from Submarine
Volcanic Habitat
, Pyrodictum
Spherical cells Key genera: Pyrolobus
About 1mm in diameter Ignicoccus
Forms aggregates of up to Staphylothermus
100 cells Staphylothermus
Chemoorganotroph that grows
optimally at 92 degrees celsius Shallow water thermal springs and
Crenarchaeota from Submarine deep-sea hydrothermal vents
Desulfurococcus is a strictly Volcanic Habitats harbor the most thermophilic of
anaerobic S^0-reducing organism all known Archaea
Ignicoccus grows optimally at 90
degrees celsius and its metabolism
is H2/S^0 based Optimum growth temperature
Desulfurococcus and Ignicoccus above 100 degrees celsius
Ignicoccus contains an outer
membrane similar to that of Strain 121 can grow up
gram-negative bacteria Pyrodictum and Pyrolobus to 121 degrees celsius
Pyrolobus fumarii
