Classification
Higher order taxa:
Archaea; Crenarchaeota; Thermoprotei; Desulfurococcales; Pyrodictiaceae
Species:
Pyrolobus fumarii (Synonyms: Pyrolobus Blochl et al. 1999)
Description and Significance
Pyrolobus fumarii are made up of cells that are regulary to irregulary lobed cocci. Chemolithoautotrophic growth by anaerobic and microaerophilic H2 oxidation with NO3-, S2O32-, and O2 as electron accepters. By doing so well at temperatures of 95ºC to 113ºC, our knowledge about the upper limits of life is expanded.
Genome Structure
DNA Base composition Determined by a direct analysis of its mononucleosides and melting point analysis,Pyrolobus fumarii has a cytosine-guanine composition of 52.9mol% and 53.4mol% respectively. (Blöchl et al. 1997)
DNA-DNA homology The closest relatives of Pyrolobus fumarii are members of Pyrodictium' based off 16S rRNA partial sequencing. There is insignificant DNA homology between Pyrolobus fumarii, Pyrodictium occultum, and Pyrodictium abyssi as shown in a DNA/DNA hybridization. (Blöchl et al. 1997)
Cell Structure
Pyrolobus fumarii are cells are regularly to irregularly lobe-shaped cocci (0.7-2.5 microm in diameter) arranged singly and
