Pseudomonadota is a major phylum of Gram-negative bacteria. Currently, they are considered the predominant phylum within the realm of bacteria. They are naturally found as pathogenic and free-living (non-parasitic) genera. The phylum comprises six classes Acidithiobacillia, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Hydrogenophilia, and Zetaproteobacteria. The Pseudomonadota are widely diverse, with differences in morphology, metabolic processes, relevance to humans, and ecological influence.
Desulfovibrionales are a taxonomic order of bacteria belonging to the phylum Thermodesulfobacteriota, with four families. They are Gram-negative. The majority are sulfate-reducing, with the exception of Lawsonia and Bilophila. All members of this order are obligately anaerobic. Most species are mesophilic, but some are moderate thermophiles.
The Desulfuromonadales are an order within the Thermodesulfobacteriota. Various members of the Desulfomonadales are capable of anaerobic respiration utilizing a variety of compounds as electron acceptors, including sulfur, Mn(IV), Fe(III), nitrate, Co(III), Tc(VII), U(VI) and trichloroacetic acid
The Syntrophobacterales are an order of Thermodesulfobacteriota. All genera are strictly anaerobic. Many of the family Syntrophobacteraceae are sulfate-reducing. Some species are motile by using one polar flagellum.
The Desulfurellaceae are a small family of Campylobacterota, given their own order and class. The family was classified under Deltaproteobacteria per established nomenclature in LPSN, but phylogenetic evidence has moved it elsewhere.
The Desulfuromonadaceae are a family within the Thermodesulfobacteriota.
The "Pelobacteraceae" are a bacterial family in the order Desulfuromonadales. The species are anaerobic and have a fermentative metabolism.
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.
Thermodesulforhabdus is an acetate-oxidizing bacterial genus from the order Syntrophobacterales. Up to now there is only on species of this genus known.
Desulfatibacillum is a bacteria genus from the order Desulfobacterales.
Desulfatirhabdium is a bacteria genus from the order Desulfobacterales.
Desulfoluna is a bacteria genus from the order Desulfobacterales.
Desulforegula is a bacteria genus from the order Desulfobacterales.
Geothermobacter is a thermophilic genus of bacteria from the order Desulfuromonadales with one known species.
Bacteriovoracales is an order of bacteria.
Bdellovibrionota is a phylum of bacteria.
The Desulfococcaceae are a family in the order Desulfobacterales.
The Desulfosarcinaceae are a family in the order Desulfobacterales.
Desulfonatronovibrionaceae is a family of bacteria belonging to the phylum Thermodesulfobacteriota.
The Geobacterales are an order within the Thermodesulfobacteriota.
