Methanogenium
''Methanogenium'' is a genus of archaeans in the family Methanomicrobiaceae. The type species is ''Methanogenium cariaci''. Description and habitat The species within ''Methanogenium'' are coccoid in shape and Gram-negatives and, like other methanogenic archaea, they produce methane from carbon dioxide, hydrogen or formate as substrates. Although they occasionally have flagella, they are non-motile. They are strictly anaerobic, and can be found in marine and lake sediments that lack oxygen.

Methanogenium Frigidum
''Methanogenium frigidum'' is a psychrophilic, H2-using methanogen from Ace Lake, Antarctica. Description and metabolism Cells are psychrophilic, irregular, slightly halophilic and non- motile coccoids (diameter 1.2 to 2.5 μm). They require salt to grow. They prefer low temperatures: their optimal temperature is 15 °C, and they cannot grow at 18 °C–20 °C. They reduce carbon dioxide with hydrogen to produce methane, but it may be possible that they use other substrates as well. One experiment showed that these cells grow best in the presence of yeast extract. Genome The genome of this species differs from those of archaea that prefer higher temperatures. It contains more polar amino acids, particularly Gln and Thr, and fewer non-polar ones, particularly Leu. Unlike hyperthermophiles, in psychrophiles, the GC content is the most important factor to the stability of the tRNA Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for solubl ...

Methanogenium Boonei
''Methanogenium boonei'' is a methanogenic archaean. Cells are non- motile irregular cocci 1.0-2.5 μm in diameter. This mesophile grows optimally at 19.4 °C, pH6.4-7.8, salinity 0.3-0.5 M Na+. It was first isolated from Skan Bay, Alaska. Description and metabolism The cells are irregular and coccoid in shape, non-motile, approximately 1.0–2.5 μm in diameter. These mesophiles grow optimally at a temperature of 19.4 °C, pH 6.4–7.8 and salinity of 0.3–0.5 M Na+. This is a strictly anaerobic species, and individuals can use carbon dioxide with hydrogen or formate as substrates to produce methane Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms).

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 " Altarcha ...

Archaea
Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of ''Haloquadratum walsbyi''. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

The All-Species Living Tree Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB Project, ARB, SILVA rRNA database project, and List of Prokaryotic names with Standing in Nomenclature, LPSN, with the aim of assembling a database of 16S ribosomal RNA, 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S ribosomal RNA, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics.
