The myxobacteria are a group of bacteria that predominantly live in the soil and feed on insoluble organic substances. The myxobacteria have very large genomes relative to other bacteria, e.g. 9–10 million nucleotides except for Anaeromyxobacter and Vulgatibacter. One species of myxobacteria, Minicystis rosea, has the largest known bacterial genome with over 16 million nucleotides. The second largest is another myxobacteria Sorangium cellulosum.
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 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.
Desulfovibrionaceae is a family of bacteria belonging to the phylum Thermodesulfobacteriota.
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.
Desulfomonile is a Gram negative, strict anaerobe and non-motile bacterial genus from the family of Syntrophaceae. Desulfomonile bacteria can reduce sulfur oxyanions to H2S.
Desulfatibacillum is a bacteria genus from the order Desulfobacterales.
Desulfatirhabdium 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.
Deferrisoma is a genus of bacteria from the phylum Thermodesulfobacteriota.
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.
