Desulfurococcaceae
In taxonomy, the Desulfurococcaceae are a family of the disc-shaped anaerobic microorganisms belonging to the order Desulfurococcales, in the domain Archaea. Members of this family are distinguished from the other family ( Pyrodictiaceae) in the order Desulfurococcales by having an optimal growth temperature below 100 °C, rather than above 100 °C, and by being more diverse. Several genera of the family have been identified. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH).

Desulfurococcales
The Desulfurococcales are an order of the Thermoprotei, part of the kingdom Archaea.

Staphylothermus
In taxonomy, ''Staphylothermus'' is a genus of the Desulfurococcaceae. Taxonomy Desulfurococcaceae are anaerobic, sulfur respiring, extreme thermophiles. Desulfurococcaceae share the same family as Desulfurococcus. Two species of ''Staphylothermus'' have been identified: ''S. marinus'' and ''S. hellenicus''. They are both heterotrophic, anaerobic members of the domain Archea. Cell structure ''Staphylothermus marinus'' has a unique morphology. When nutrient levels are low, it forms grape-like clusters that range in diameter from 0.5–1.0 mm up to 100 clusters large. At high nutrient levels, large clustered cells up to 15 μm in diameter are found. The S-layer is made of a glycoprotein called tetrabrachion. Tetrabrachion is stable at high temperatures and resistant to chemicals that typically denature proteins. Tetrabrachion is built from 92,000 kDa polypeptides forming projections that react with other tetrabrachion sub units making a lattice framework that covers th ...

Thermosphaera
''Thermosphaera'' is a genus of the Desulfurococcaceae. They are a group of prokaryotic organisms which have been discovered in extremely hot environments such as sulfur springs, volcanoes, and magma pools. Isolates of ''Thermosphaera'' were first identified in 1998 from the Obsidian Pool in Yellowstone National Park. Cell structure and metabolism Cells of ''Thermosphaera'' are cocci (spherical) and form grape-like aggregates during the exponential growth phase. In the late exponential and stationary growth phases, smaller groups, including some single cells, were visible. Aggregates were shown to have several flagella; single cells could have as many as eight. The cell envelope is an amorphous layer covering a cytoplasmic membrane. Temperatures exceeding 92 °C inhibits growth, as does sulfur and hydrogen. ''Thermosphaera'' cells are heterotrophic, processing energy from yeast. Ecology ''Thermosphaera'' are found mainly in sulfuric pools, where they thrive on the ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeropyrum
In taxonomy, ''Aeropyrum'' is a genus of the Desulfurococcaceae. Etymology The name ''Aeropyrum'' derives from:Greek noun ''aer, aeros (ἀήρ, ἀέρος)'', air; Greek neuter gender noun ''pur'', fire; New Latin neuter gender noun ''Aeropyrum'', air fire, referring to the hyperthermophilic respirative character of the organism. Species The genus contains 2 species (including basonyms and synonyms), namely * '' A. camini'' ( Nakagawa ''et al.'' 2004, ; Latin genitive case noun ''camini'', of a chimney, relating to its isolation from a hydrothermal vent chimney.) * '' A. pernix'' ( Sako ''et al.'' 1996, (Type species of the genus).; Latin neuter gender adjective ''pernix'', nimble, active, agile, indicating high motility in microscopic inspection.) See also * Bacterial taxonomy Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria. In the scientific classification established by Carl Linnaeus, each species has to be assigned to a genus ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignicoccus
''Ignicoccus'' is a genus of hyperthermophillic Archaea living in marine hydrothermal vents. They were discovered in samples taken at the Kolbeinsey Ridge north of Iceland, as well as at the East Pacific Rise (at 9 degrees N, 104 degrees W) in 2000. Systematics According to the comparisons of 16S rRNA genes, ''Ignicoccus'' represents a new, deeply branching lineage within the family of the Desulfurococcaceae. Three species are known: ''I. islandicus'', ''I. pacificus'' and ''I. hospitalis'' strain KIN4I. Cell structure The archaea of the genus ''Ignicoccus'' have tiny coccoid cells with a diameter of about 2 µm, that exhibit a smooth surface, an outer membrane and no S-layer. They have a previously unknown cell envelope structure—a cytoplasmic membrane, a periplasmic space (with a variable width of 20 to 400 nm, containing membrane-bound vesicles), and an outer membrane (approximately 10 nm wide, resembling the outer membrane of gram-negative bacteria).
