Thermoanaerobacteriales
The Thermoanaerobacterales is a polyphyletic order of bacteria placed within the polyphyletic 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. National Council for Science and the Environment, Washington DC./ref> Phylogeny The Thermoanaerobacterales, as previously mentioned, is polyphyletic A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to grou ...

Clostridia
The Clostridia are a highly polyphyletic class of Bacillota, including '' Clostridium'' and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them. Species of the class ''Clostridia'' are often but not always Gram-positive (see ''Halanaerobium'') and have the ability to form spores. Studies show they are not a monophyletic group, and their relationships are not entirely certain. Currently, most are placed in a single order called Clostridiales, but this is not a natural group and is likely to be redefined in the future. Most species of the genus ''Clostridium'' are saprophytic organisms that ferment plant polysaccharides and are found in many places in the environment, most notably the soil. However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus ''Clostridium'' are among the most dangerous known. Examples are tetanus ...

Thermoanaerobacteraceae
The Thermoanaerobacteraceae is a highly polyphyletic family of bacteria placed within the class clostridia. Originally placed within the highly polyphyletic class Clostridia and order Thermoanaerobacterales, according to the NCBI and LPSN, it is now thought to be a basal clade of the phylum Bacillota. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) and the phylogeny is based on 16S rRNA-based LTP release 111 by The All-Species Living Tree ProjectAll-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 ....

Moorella (bacterium)
''Moorella'' is a genus of bacteria belonging to the phylum Bacillota. These bacteria are thermophilic, anaerobic and endospore-forming and many species of this genus have been isolated from hot springs. Some of these species were formerly included within the genus ''Clostridium'', but after a taxonomic rearrangement of the class Clostridia, a phylogenetically distinct genus was identified, which was named ''Moorella'' in honor of the American microbiologist W.E.C. Moore. Phylogeny The current phylogeny of these bacteria has been inferred from a computational analysis of 16S ribosomal RNA genes of described species belonging to the ''Moorella Group'' (a larger group of bacteria within the family Thermoanaerobacteraceae that also includes other species actually not belonging to genus ''Moorella''). The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) See also ...

Gelria (bacterium)
''Gelria'' is a thermophilic, anaerobic, obligately syntrophic, glutamate-degrading, endospore-forming bacterial genus in the family Thermoanaerobacteraceae. The name of the genus comes from Gelre (present province of Gelderland), one of the 12 provinces in The Netherlands.

Desulfovirgula
''Desulfovirgula'' is a genus of sulfate reducing, anaerobic, endospore-forming, Gram-positive, thermophilic, motile, rod-shaped bacteria, isolated from an underground mining site in an area of Japan characterized by high geothermal activity. Up to now (December 2021) ''Desulfovirgula thermocuniculi'' is the sole known species in the genus. Electron acceptors that this organism can utilize include sulfate, sulfite, thiosulfate and elemental sulfur, while H2 (in the presence of CO2) and carboxylic acids can be utilized as electron donors.
