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.
Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
The Myxococcota are a phylum of bacteria known as the fruiting gliding bacteria. All species of this group are Gram-negative. They are predominantly aerobic genera that release myxospores in unfavorable environments.
Chloracidobacterium is a genus of the Acidobacteriota. It is currently assigned to the family Acidobacteriaceae, but phylogenetic evidence suggests that it belongs in Blastocatellia.
The Acidobacteriaceae are a family of Acidobacteriota.
The Solirubrobacterales are an order of Actinomycetota.
The Selenomonadales are an order of bacteria within the class Negativicutes; unlike most other members of Bacillota, they are Gram-negative. The phylogeny of this order was initially determined by 16S rRNA comparisons. More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species. On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes. Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae. Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.
The Coriobacteriia are a class of Gram-positive bacteria within the Actinomycetota phylum. Species within this group are nonsporulating, strict or facultative anaerobes that are capable of thriving in a diverse set of ecological niches. Gordonibacter species are the only members capable of motility by means of flagella within the class. Several species within the Coriobacteriia class have been implicated with human diseases that range in severity. Atopobium, Olsenella, and Cryptobacterium species have responsible for human oral infections including periodontitis, halitosis, and other endodontic infections. Eggerthella species have been associated with severe blood bacteraemia and ulcerative colitis.
Patulibacter is a genus of bacteria from the family Patulibacteraceae.
The Silvanigrellaceae are the only family of the order Silvanigrellales, of the class Oligoflexia.
The Blastocatellales is an order of Acidobacteriota within the class Blastocatellia.
The Atopobiaceae are a family of Actinomycetota.
Isosphaeraceae is a family of bacteria.
Bdellovibrionota is a phylum of bacteria.
Thermosediminibacteraceae is a family of Gram positive bacteria in the class Clostridia.
Tepidanaerobacteraceae is a family of Gram positive bacteria in the class Clostridia.
The "Acidobacteriia" is a class of Acidobacteriota.
The Bryobacteraceae are a family of Acidobacteriota.
The Blastocatellaceae is a family of bacteria.
The Acanthopleuribacteraceae is a family of Acidobacteriota.
