Bacteroidales is an order of bacteria. [2] [3] Notably it includes the genera Prevotella and Bacteroides , which are commonly found in the human gut microbiota.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature [3] and National Center for Biotechnology Information (NCBI). [4]

The phylum Bacteroidota is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals.
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 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.
Prevotellaceae is a family of bacteria from the order Bacteroidales. As a member of the phylum Bacteroidota, its species are gram negative – meaning their outer cell wall contains lipopolysaccharides. Since they are anaerobes, members of Prevotellaceae can live in areas where there is little to no oxygen – such as the guts of mammals.
The order Flavobacteriales comprises several families of environmental bacteria.
The Sphingobacteriales is an order of environmental bacteria.
The family Saprospiraceae is composed of environmental bacteria. The members of this family are important to the breakdown of complex organic compounds in the environment.
The Acidobacteriaceae are a family of Acidobacteriota.
Bergey's Manual of Systematic Bacteriology is the main resource for determining the identity of prokaryotic organisms, emphasizing bacterial species, using every characterizing aspect.
The FCB group is a superphylum of bacteria named after the main member phyla Fibrobacterota, Chlorobiota, and Bacteroidota. The members are considered to form a clade due to a number of conserved signature indels.
The Marinilabiliaceae are a family of bacteria.
Saprospirales is an order of bacteria in the phylum Bacteroidota.
Planctomycetia is a class of aquatic bacteria.
Gemmatimonas is a Gram-negative, rod-shaped, motile and non-spore-forming genus of bacteria from the family of Gemmatimonaceae.
Pelagicoccus is a Gram-negative genus of bacteria from the family of Puniceicoccaceae.
The Opitutales is an order in the phylum Verrucomicrobiota.
The Opitutaceae are a Gram-negative and chemoheterotrophic order of the domain Bacteria. Opitutaceae bacteria were isolated from soil and coastal marine springs.
The "Acidobacteriia" is a class of Acidobacteriota.
