Thermodesulfobiaceae
The family Thermodesulfobiaceae according to the LPSN is located within the order Thermoanaerobacterales and class Clostridia. However, according to the All-Species Living Tree Project it lies outside the clade Bacillota and the genus '' Caldanaerovirga'' does not belong to the clade, i.e. Thermodesulfobiaceae is polyphyletic. Phylogeny This family formerly included two genera ('' Thermodesulfobium'' and '' Coprothermobacter''); however, the taxonomy of this family is under review because the genus '' Coprothermobacter'' was excluded from this family in March 2018, after several genomic analyses confirmed the differences between them. The most recent classification updates are already reported by the National Center for Biotechnology Information (NCBI), even though some taxonomy considering former versions of the List of Prokaryotic names with Standing in Nomenclature (LPSN), or old releases of 16S rRNA-based tree from The All-Species Living Tree Project, All-Species Living Tree ...

Thermoanaerobacterales
The Thermoanaerobacterales is a polyphyletic order (biology), order of bacteria placed within the polyphyletic class (taxonomy), class Clostridia, and encompassing four families: the Thermoanaerobacteraceae, the Thermodesulfobiaceae, the Thermoanaerobacterales Family III. Incertae Sedis, and the Thermoanaerobacterales Family IV. Incertae Sedis, and various unplaced genera. This order is noted for the species' abilities to survive in extreme environments without oxygen and of relatively elevated temperatures for a living being (up to 80-90 °C). An example organism in this order is ''Thermoanaerobacter ethanolicus''.C.Michael Hogan. 2010''Extremophile''. eds. E.Monosson & C.Cleveland, Encyclopedia of Earth.

Coprothermobacter
''Coprothermobacter'' is a genus of rod-shaped microorganisms, belonging to the bacterial family '' Coprothermobacteraceae'' of the phylum ''Coprothermobacterota''. This taxonomic genus has been reclassified in 2018, after different phylogenetic studies showed that these bacteria represented a deeply branched taxon of the domain ''Bacteria''; consequently, the clade including this genus has been classified in a separate phylum from ''Firmicutes'', the phylum where it was included before reclassification. According to the first description of this genus, the etymology of its name derives from Greek words "''kopros''", meaning dung, from the source where one of the species ('' Coprothermobacter proteolyticus'') was isolated, and "''thermos''", meaning hot, warm, because of the relatively high temperatures at which these bacteria are able to grow, which can be as high as 75°C. Actually, very few known bacterial species are included in this genus, which are characterized by sharing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteria
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of Prokaryote, prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, suc ...

Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...

The All-Species Living Tree Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB, SILVA rRNA database project, and LPSN, with the aim of assembling a database of 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 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 off for size and many phylum level clades are not correctly resolved (such as the Firmicutes).

Bacillota
The Bacillota (synonym Firmicutes) are a phylum of bacteria, most of which have Gram-positive cell wall structure. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). A few Bacillota, such as '' Megasphaera'', '' Pectinatus'', '' Selenomonas'', and '' Zymophilus'' from the class Negativicutes, have a porous pseudo-outer membrane that causes them to stain Gram-negative. Many Bacillota produce endospores, which are resistant to desiccation and can survive extreme conditions. They are found in various environments, and the group includes some notable pathogens. Those in one family, the Heliobacteria, produce energy through anoxygenic photosynthesis. Bacillota play an important role in beer, wine, and cider spoilage. Taxonomy The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The name "Firmicutes" was derived from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermodesulfobacteriota
The Thermodesulfobacteriota, or Desulfobacterota, are a phylum of anaerobic Gram-negative bacteria. Many representatives are sulfate-reducing bacteria, others can grow by disproportionation of various sulphur species, reduction or iron, or even use external surfaces as electron acceptors ( exoelectrogens). They have highly variable morphology: vibrio, rods, cocci, as well as filamentous cable bacteria. Individual members of Desulfobacterota are also studied for their bacterial nanowires or syntrophic relationships. Taxonomy The bacterial phylum Desulfobacterota has been created by merging: 1) the well-established class Thermodesulfobacteria, 2) the proposed phylum Dadabacteria, and 3) various taxa separated from the abandoned non-monophyletic class "Deltaproteobacteria" alongside three other phyla: Myxococcota, Bdellovibrionota, and SAR324. Environment In contrast to their close relatives, the aerobic phyla Myxococcota and Bdellovibrionota, Desulfobacterota are predom ...
