The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:
The Alicyclobacillaceae are a family of Gram-positive bacteria. All members of this family are aerobic and form endospores.
Campylobacterota are a phylum of bacteria. All species of this phylum are Gram-negative.
Natronorubrum is a genus in the family Halobacteriaceae.
Thermoanaerobacter is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Deferribacter is a genus in the phylum Deferribacterota (Bacteria).
Armatimonadota is a phylum of gram-negative bacteria.
There are several models of the Branching order of bacterial phyla, one of these was proposed in 1987 paper by Carl Woese.
Desulfosporosinus is a genus of strictly anaerobic, sulfate-reducing bacteria, often found in soil.
Meiothermus is a genus of Deinococcota bacteria. Members of Meiothermus can be reliably distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of three conserved signature indels (CSIs) found in the proteins: 5-methyltetrahydrofolate–homocysteine methyltransferase, cadmium transporter and polynucleotide phosphorylase and are exclusively shared by species of this genus. Meiothermus is also different than the Thermus genus, which it was originally a member of, in their optimum growth temperatures, with Meiothermus being able to grow in colder environments. Meiothermus was first isolated with Thermus in alkaline and neutral hot springs in Kamchatka, Russia and Yellowstone National Park, USA.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Bacillota. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
The Natranaerobiaceae are a family of bacteria placed within the class Clostridia. This family contains the thermophilic bacterial species Natranaerobius thermophilus and the related species Natranaerobaculum magadiense.
Carboxydocella is a Gram-positive and obligate anaerobe bacterial genus from the family of Syntrophomonadaceae.
Laceyella is a Gram-positive, thermophilic, spore-forming and aerobic bacterial genus from the family of Thermoactinomycetaceae. The genus Laceyella is namened after the English microbiologist John Lacey.
Planifilum is a Gram-positive and aerobic bacterial genus from the family of Thermoactinomycetaceae.
Anaerolineaceae is a family of bacteria from the order of Anaerolineales. Anaerolineaceae bacteria occur in marine sediments. There are a total of twelve genera in this family, most of which only encompass one species. All known members of the family are Gram-negative and non-motile. They also do not form bacterial spores and are either mesophilic or thermophilic obligate anaerobes. It is also known that all species in this family are chemoheterotrophs.
Alicyclobacillus acidocaldarius is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic, thermophilic, and produce endospores. The first identified strains of A. acidocaldarius were from geysers in Yellowstone National Park and fumerole soil in Hawaii Volcano National Park. The species was originally classified as Bacillus acidocaldarius in 1971, but further 16S rRNA studies found that the species belonged in the newly created genus Alicyclobacillus. The species name is derived from the Latin acidum (acid) and caldarius, referring to the acidic and high temperature environments from which it was first isolated. Thomas D. Brock was one of the researchers who first categorized the species; his discovery of Thermus aquaticus allowed for other researchers to discover Taq polymerase and polyermase chain reaction (PCR).
Effusibacillus is a genus of Gram-positive, rod-shaped, aerobic, spore-forming bacteria.
Effusibacillus pohliae is a species of Gram positive, aerobic, thermophilic bacterium. The cells are rod-shaped and form spores. It was first isolated from Mount Melbourne, Antarctica. The species is named after the genus of Pohlia nutans, a species of moss that was colonizing the area where the type strain was isolated. E. pohliae has also been isolated from a geothermal heat pump in South Korea.
Rhodothermus is a genus of bacteria.
