Are Sulfolobus Thermoacidophiles?
Sulfolobus solfataricus is an extremely thermophilic and acidophilic organism that thrives in hot acidic habitats, growing optimally between pH values of 3 and 4 at 70 to 90°C (7, 12).
Where is Sulfolobus found?
Sulfolobus is located almost wherever there is volcanic activity. They strive in environments where the temperature is about 80oC with a pH at about 3 and sulfur present. Another species, S. tokodaii, has been located in an acidic spa in Beppu Hot Springs, Kyushu, Japan.
Does Sulfolobus have a flagella?
Flagella have previously been isolated only from Sulfolobus shibatae (19). This report describes a study of the flagellar system of the thermoacidophilic crenarchaeon Sulfolobus solfataricus, including the generation of an flaJ knockout strain that is nonmotile.
Is Sulfolobus prokaryotic or eukaryotic?
prokaryotic
The eukaryotic similarities are further underlined by the discovery that Sulfolobus species provide the first examples of any prokaryotic organisms containing multiple chromosome replication origins (Lundgren et al., 2004; Robinson et al., 2004; Robinson and Bell, 2007), previously considered to be one of the main …
Is Sulfolobus heterotrophic or autotrophic?
Complex lipids from the thermoacidophilic facultative autotroph Sulfolobus acidocaldarius, as well as a strictly autotrophic isolate, were compared between cells grown on yeast extract and elemental sulfur. Lipids from both organisms grown autotrophically were nearly identical.
Is Sulfolobus living or nonliving?
“Sulfolobus: a new genus of sulfur-oxidizing bacteria living at low pH and high temperature”.
Is Sulfolobus an archaebacteria or eubacteria?
Sulfolobus is a genus of microorganism in the family Sulfolobaceae. It belongs to the archaea domain. Sulfolobus species grow in volcanic springs with optimal growth occurring at pH 2-3 and temperatures of 75-80 °C, making them acidophiles and thermophiles respectively.
Where is Sulfolobus solfataricus found?
Sulfolobus solfataricus is a thermoacidophile, and was first characterized in sulfur-rich volcanic springs in Yellowstone National Park. Strains of S. solfataricus have also been found in hot mud pools in the Solfatara crater north of Naples, Italy. It has also been discovered in El Salvador and the Dominica.
What is the shape of Sulfolobus virus?
Sulfolobus islandicus filamentous virus (SIFV) virions (1950 × 24 nm) are enveloped with a 4 nm thick lipid-containing layer and have a flexible filamentous morphology. The ends of the virion taper and end in mop-like structures. The cross-section of the virion is elliptical.
Is Sulfolobus heterotrophic?
Sulfolobus is one of the best characterized genera of the Archaea. It grows aerobically and either facultatively or obligately heterotrophically and can be easily cultivated in liquid media and on solid supports. Some Sulfolobus species, like S. solfataricus, have become model organisms of the Crenarchaeota.
What is Sulfolobus solfataricus P2 strain used for?
The S. solfataricus P2 genome has been manipulated for studies of transcription, translation, the cell cycle, and other genetic events. Currently, the Sulfolobus solfataricus 98/2 strain is being sequenced for further studies. Sulfolobus solfataricus has a spherical shape and a clockwise flagellum.
