Pseudomonadota is a major phylum of Gram-negative bacteria. The renaming of several prokaryote phyla in 2021, including Pseudomonadota, remains controversial among microbiologists, many of whom continue to use the earlier name Proteobacteria, of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Yersinia, Legionella, and many others. Others are free-living (non-parasitic) and include many of the bacteria responsible for nitrogen fixation.
Enterocloster clostridioformis, formerly known as Clostridium clostridioforme, is an anaerobic, motile, Gram-positive bacterium.
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
Afifella is a genus in the phylum Pseudomonadota (Bacteria). Afifella are found in marine and estuarine settings, including microbial mats. They are anaerobes, with one cultured representative capable of photosynthesis.
Algicola is a genus in the phylum Pseudomonadota (Bacteria).
Armatimonadota is a phylum of gram-negative bacteria.
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.
Thermoanaerobacter acetoethylicus, formerly called Thermobacteroides acetoethylicus, is a species of thermophilic, nonspore-forming bacteria.
Coprothermobacter proteolyticus, formerly Thermobacteroides proteolyticus, is a thermophilic, non-spore-forming bacteria.
Microbispora is a Gram-positive, mesophilic, thermophilic and non-motile bacterial genus from the family of Streptosporangiaceae.
Roseivirga is a strictly aerobic genus from the phylum Bacteroidota.
Caldanaerobacter is a Gram-positive or negative and strictly anaerobic genus of bacteria from the family of Thermoanaerobacteraceae.
Coprothermobacterota is a phylum of nonmotile, rod-shaped bacteria.
Coprothermobacteria is a taxonomic class of bacteria in the phylum Coprothermobacterota.
Coprothermobacterales is a taxonomic order of thermophilic bacteria in the class Coprothermobacteria of the phylum Coprothermobacterota.
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.
Coprothermobacter platensis is a species of moderately thermophilic and strictly anaerobic bacterium belonging to the family Coprothermobacteraceae within the phylum Coprothermobacterota.
Alkalihalobacillus is a genus of gram-positive or gram-variable rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Alkalihalobacillus alcalophilus.
Peribacillus is a genus of rod-shaped bacteria that exhibits Gram-positive or Gram-variable staining that belongs in the family Bacillaceae within the order Bacillales. The type species for this genus is Peribacillus simplex.
Mesobacillus is a genus of gram-positive or gram-variable, rod-shaped bacteria in the family Bacillaceae within the order Bacillales. The type species for this genus is Mesobacillus jeotgali.
