List Of Sequenced Archaeal Genomes
This list of sequenced archaeal genomes contains all the archaea Archaea ( ) is a Domain (biology), domain of organisms. Traditionally, Archaea only included its Prokaryote, prokaryotic members, but this has since been found to be paraphyletic, as eukaryotes are known to have evolved from archaea. Even thou ... known to have publicly available complete genome sequences that have been assembled, annotated and deposited in public databases. ''Methanococcus jannaschii'' was the first archaeon whose genome was sequenced, in 1996. Currently in this list there are 39 genomes belonging to Crenarchaeota species, 105 belonging to the Euryarchaeota, 1 genome belonging to Korarchaeota and to the Nanoarchaeota, 3 belonging to the Thaumarchaeota and 1 genome belonging to an unclassified Archaea, totalling 150 Archaeal genomes.

Archaea
Archaea ( ) is a Domain (biology), domain of organisms. Traditionally, Archaea only included its Prokaryote, prokaryotic members, but this has since been found to be paraphyletic, as eukaryotes are known to have evolved from archaea. Even though the domain Archaea Cladistics, cladistically includes eukaryotes, the term "archaea" (: archaeon , from the Greek "ἀρχαῖον", which means ancient) in English still generally refers specifically to prokaryotic members of Archaea. Archaea were initially Taxonomy (biology), classified as bacteria, receiving the name archaebacteria (, in the Archaebacteria Kingdom (biology), kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from Bacteria and Eukaryote, Eukaryota. Archaea are further divided into multiple recognized phylum, phyla. Classification is difficult because most have not been Isolation (microbiology), isolated in a laboratory and have been detected only by their Gene, gene s ...

Metallosphaera Sedula
''Metallosphaera sedula'' is a species of ''Metallosphaera'' that is originally isolated from a volcanic field in Italy. ''Metallosphaera sedula'' can be roughly translated into “metal mobilizing sphere” with the word “sedulus” meaning busy, describing its efficiency in mobilizing metals. ''M. sedula'' is a highly thermoacidophilic Archaean that is unusually tolerant of heavy metals. Significance Due to its ability to oxidize pyrite (FeS2), ''M. sedula'' has the potential to be used for coal depyritization. With increased awareness of the environmental impact of the combustion of coals, the idea of coal pollution mitigation or “clean coal” was born. While there are several focuses of mitigation, one of which is the removal of impurities, such as sulfur found in pyrite, prior to combustion. The combustion of sulfur leads to the formation of SO2, which has adverse health effects, and contributes to acid rain. Abiotic removal of pyrite from coal is currently the prefe ...

Thermosphaera Aggregans
''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 ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staphylothermus Marinus
''Staphylothermus'' is a genus of archaeans in the family 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 co ...
