Armatimonadota is a phylum of gram-negative bacteria.
Armatimonadota was originally described solely on the basis of environmental 16S rRNA gene clone sequences, and was temporarily titled candidate phylum OP10. However, in 2011 a bacterial strain belonging to the phylum was isolated from an aquatic plant in Japan. The species was named Armatimonas rosea and was the first member of its phylum, genus, and species. [2]
Armatimonas rosea , an aerobic chemoheterotrophic bacterium, strain YO-36T, was isolated from rhizoplane of an aquatic plant (a reed, Phragmites australis ) inhabiting a freshwater lake in Japan. [2]
Chthonomonas calidirosea , an aerobic, saccharolytic, obligately thermophilic, motile, non-spore-forming bacterium, strain T49(T), was isolated from geothermally heated soil at Hell's Gate, Tikitere, New Zealand. [3]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [10] and National Center for Biotechnology Information (NCBI). [11]
The Aquificota phylum is a diverse collection of bacteria that live in harsh environmental settings. The name Aquificota was given to this phylum based on an early genus identified within this group, Aquifex, which is able to produce water by oxidizing hydrogen. They have been found in springs, pools, and oceans. They are autotrophs, and are the primary carbon fixers in their environments. These bacteria are Gram-negative, non-spore-forming rods. They are true bacteria as opposed to the other inhabitants of extreme environments, the Archaea.
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 Thermotogota are a phylum of the domain Bacteria. The phylum contains a single class, Thermotogae. The phylum Thermotogota is composed of Gram-negative staining, anaerobic, and mostly thermophilic and hyperthermophilic bacteria.
Rubrobacter is a genus of Actinomycetota. It is radiotolerant and may rival Deinococcus radiodurans in this regard.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
Chloracidobacterium is a genus of the Acidobacteriota. It is currently assigned to the family Acidobacteriaceae, but phylogenetic evidence suggests that it belongs in Blastocatellia.
Kribbella is a genus of bacteria first discovered in 1999.
Deinococcus is in the monotypic family Deinococcaceae, and one genus of three in the order Deinococcales of the bacterial phylum Deinococcota highly resistant to environmental hazards. These bacteria have thick cell walls that give them Gram-positive stains, but they include a second membrane and so are closer in structure to Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation. Whereas other bacteria change their structure in the presence of radiation, such as by forming endospores, Deinococcus tolerate it without changing their cellular form and do not retreat into a hardened structure. They are also characterized by the presence of the carotenoid pigment deinoxanthin that give them their pink color. They are usually isolated according to these two criteria. In August 2020, scientists reported that bacteria from Earth, particularly Deinococcus bacteria, were found to survive for three years in outer space, based on studies conducted on the International Space Station. These findings support the notion of panspermia, the hypothesis that life exists throughout the Universe, distributed in various ways, including space dust, meteoroids, asteroids, comets, planetoids or contaminated spacecraft.
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
Armatimonas rosea is a Gram-negative bacterium and also the first species to be characterized within the phylum Armatimonadota. The Armatimonadota were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to A. rosea's discovery.
Chthonomonas calidirosea is a Gram-negative bacterium and also the first representative of the new class Chthonomonadetes within the phylum Armatimonadota. The Armatimonadota were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to C. calidirosea's relative, Armatimonas rosea's discovery. It is now known that bacterial communities from geothermal environments, are generally constituted by, at least 5–10% of bacteria belonging to Armatimonadota.
Fimbriimonas ginsengisoli is a Gram-negative bacterium and the first representative of the class Fimbriimonadia within the phylum Armatimonadota. The Armatimonadota were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to F. ginsengisoli's relative, Armatimonas rosea's discovery.
Thermomonosporaceae is a family of bacteria that share similar genotypic and phenotypic characteristics. The family Thermomonosporaceae includes aerobic, Gram-positive, non-acid-fast, chemo-organotrophic Actinomycetota. They produce a branched substrate mycelium bearing aerial hyphae that undergo differentiation into single or short chains of arthrospores. All species of Thermomonosporaceae share the same cell wall type, a similar menaquinone profile in which MK-9(H6)is predominant, and fatty acid profile type 3a. The presence of the diagnostic sugar madurose is variable, but can be found in most species of this family. The polar lipid profiles are characterized as phospholipid type PI for most species of Thermomonospora, Actinomadura and Spirillospora. The members of Actinocorallia are characterized by phospholipid type PII.
Pelotomaculum is a Gram-positive strictly anaerobic, mesophilic, thermophilic and non-motile bacterial genus from the family of Peptococcaceae.
Microlunatus is a Gram-positive, non-spore-forming, mesophilic, aerobic and non-motile bacterial genus from the family of Propionibacteriaceae.
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.
Hydrogenobacter is a genus of bacteria, one of the few in the phylum Aquificota. Type species is H. thermophilus. This genus belongs to Bacteria as opposed to the other inhabitants of extreme environments, the Archaea.
Hippea is an obligate anaerobic and moderately thermophilic bacteria genus from the family of Desulfobacteraceae. Hippea is named after the German microbiologist Hans Hippe.
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.
Capsulimonas is a Gram-negative, non-spore-forming, aerobic and non-motile genus of bacteria from the family of Capsulimonadaceae with one known species. Capsulimonas corticalis has been isolated from the surface of a beech
