Methanothrix Soehngenii
''Methanothrix soehngenii'' is a species of methanogenic archaea. Its cells are non- motile, non-spore-forming, rod-shaped (0.8×2 μm) and are normally combined end to end in long filaments, surrounded by a sheath-like structure. It is named in honour of N. L. Söhngen. Metabolism Unlike other methanogenic archaea, ''Methanothrix soehngenii'' cannot reduce carbon dioxide with hydrogen to produce methane. Its sole source of energy is acetate An acetate is a salt (chemistry), salt formed by the combination of acetic acid with a base (e.g. Alkali metal, alkaline, Alkaline earth metal, earthy, Transition metal, metallic, nonmetallic or radical Radical (chemistry), base). "Acetate" als .... Genome The tRNAala gene of ''Methanothrix soehngenii'' differs from those of other archaea in that it encodes a terminal CCA 3′.

Methanosaeta
In taxonomy, ''Methanosaeta'' is a genus of microbes within Methanosaetaceae. Like other species in this family, those of ''Methanosaeta'' metabolize acetate as their sole source of energy. The genus contains two species, ''Methanosaeta concilii'', which is the type species (type strain GP6) and ''Methanosaeta thermophila''. For a time, some scientists believed there to be a third species, ''Methanosaeta soehngenii'', but because it has not been described from a pure culture, it is now called ''Methanothrix soehngenii''. Phylogeny Importance Methanosaeta species are some of the most active methanogens in wetlands, producing an extensive amount of methane on Earth. The presence of methane is both good and bad. On one hand, methane is 20 times more effective than carbon dioxide in retaining heat—thus contributing to global warming at an increasing rate. On the other hand, methane can be used as bioenergy in an effort to move from large-scale fossil fuel usage to large-scale bio ...

Methanosaeta Concilii
''Methanosaeta concilii'' is an archaeum in the disputed genus ''Methanosaeta''. It is obligately anaerobic, gram-negative and non- motile. It is rod-shaped (length 2.5 to 6.0 μm) with flat ends. The cells are enclosed within a cross-striated sheath. The type strain is GP6 (= DSM 3671 = OGC 69 = NRC 2989 = ATCC 35969). Its genome has been sequenced.

List Of Archaea Genera
This article lists the genera of the Archaea. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). Phylogeny National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups. Cladogram was taken from the GTDB release 07-RS207 (8th April 2022). The position of clades with a "question mark" are based on the additional phylogeny of the 16S rRNA-based LTP_12_2021 by The All-Species Living Tree Project. Phylum " Altarch ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Methanosarcinales
In taxonomy, the Methanosarcinales are an order of the Methanomicrobia. Large amounts of methane are produced in marine sediments but are then consumed before contacting aerobic waters or the atmosphere. Although no organism that can consume methane anaerobically has ever been isolated, biogeochemical evidence indicates that the overall process involves a transfer of electrons from methane to sulphate and is probably mediated by several organisms, including a methanogen (operating in reverse) and a sulfate-reducer (using an unknown intermediate substrate). Organisms placed within the order can be found in freshwater, saltwater, salt-rich sediments, laboratory digestors, and animal digestive systems. Most cells have cell walls that lack peptidoglycan and pseudomurein. They are strictly anaerobic and survive by producing methane. Some species use acetate as a substrate and others use methyl compounds, such as methyl amines and methyl sulfates. Phylogeny See also * List of Arc ...

Euryarchaeota
Euryarchaeota (from Ancient Greek ''εὐρύς'' eurús, "broad, wide") is a phylum of archaea. Euryarchaeota are highly diverse and include methanogens, which produce methane and are often found in intestines, halobacteria, which survive extreme concentrations of salt, and some extremely thermophilic aerobes and anaerobes, which generally live at temperatures between 41 and 122 °C. They are separated from the other archaeans based mainly on rRNA sequences and their unique DNA polymerase. Description The ''Euryarchaeota'' are diverse in appearance and metabolic properties. The phylum contains organisms of a variety of shapes, including both rods and cocci. ''Euryarchaeota'' may appear either gram-positive or gram-negative depending on whether pseudomurein is present in the cell wall. ''Euryarchaeota'' also demonstrate diverse lifestyles, including methanogens, halophiles, sulfate-reducers, and extreme thermophiles in each. Others live in the ocean, suspended with ...

Alpha Taxonomy
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolut ...
