Akkermansia is a genus in the phylum Verrucomicrobiota (Bacteria). [2] The genus was first proposed by Derrien et al. (2004), with the type species Akkermansia muciniphila (gen. nov., sp. nov). [1]
Until 2016 the genus contained a single known species, namely A. muciniphila . [2] In 2016, Akkermansia glycaniphila was isolated in the feces of a reticulated python. [3]
The name Akkermansia (Ak.ker.man'si.a.) derives from: Neo-Latin feminine gender noun Akkermansia, named after Anton Dirk Louis Akkermans (28 October 1940 – 21 August 2006), [4] a Dutch microbiologist recognized for his contribution to microbial ecology. [2] Neo-Latin neuter gender noun mucinum, mucin; Neo-Latin adjective philus from Greek adjective philos (φίλος) meaning friend, loving; Neo-Latin feminine gender adjective muciniphila, mucin-loving). [1]
Cells are oval-shaped, non-motile and stain Gram-negative. Strictly anaerobic organism. Chemo-organotrophic. Mucolytic in pure culture. [1] : 1474
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [2] and National Center for Biotechnology Information (NCBI) [5]

Akkermansia muciniphila can reside in the human intestinal tract and is currently being studied for its effects on human metabolism and health. [12]
Eggerthella is a bacterial genus of Actinomycetota, in the family Coriobacteriaceae. Members of this genus are anaerobic, non-sporulating, non-motile, Gram-positive bacilli that grow singly, as pairs, or in short chains. They are found in the human colon and feces and have been implicated as a cause of ulcerative colitis, liver and anal abscesses and systemic bacteremia.
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
Acidaminococcus is a genus in the phylum Bacillota (Bacteria), whose members are anaerobic diplococci that can use amino acids as the sole energy source for growth. Like other members of the class Negativicutes, they are gram-negative, despite being Bacillota, which are normally gram-positive.
Acrocarpospora is a genus of bacteria in the phylum Actinomycetota. The major respiratory quinone is menaquinone MK-9(H ) and use madurose, an actinomycete whole-cell sugar.
Actinoallomurus is a genus in the phylum Actinomycetota (Bacteria).
Actinocatenispora is a genus in the phylum Actinomycetota (Bacteria).
Actinocorallia is a genus in the phylum Actinomycetota (Bacteria).
Actinopolymorpha is a genus in the phylum Actinomycetota (Bacteria).
Actinospica is a genus in the phylum Actinomycetota (Bacteria).
Deferribacter is a genus in the phylum Deferribacterota (Bacteria).
Dehalogenimonas is a genus in the phylum Chloroflexota (Bacteria). Members of the genus Dehalogenimonas can be referred to as dehalogenimonads.
Cryptosporangium is a genus of bacteria in the phylum Actinomycetota.
Stigmatella is a bacterium genus in the phylum Myxococcota.
Akkermansia muciniphila is a human intestinal symbiont, isolated from human feces. It is a mucin-degrading bacterium belonging to the genus, Akkermansia, discovered in 2004 by Muriel Derrien and Willem de Vos at Wageningen University of the Netherlands. It belongs to the phylum Verrucomicrobiota and its type strain is MucT. It is under preliminary research for its potential association with metabolic disorders.
Pelotomaculum is a Gram-positive strictly anaerobic, mesophilic, thermophilic and non-motile bacterial genus from the family of Peptococcaceae.
Planifilum is a Gram-positive and aerobic bacterial genus from the family of Thermoactinomycetaceae.
Bulleidia is a Gram-positive, non-spore-forming, anaerobic and non-motile genus from the family of Erysipelotrichidae, with one known species.
Carboxydothermus is a genus of thermophilic, anaerobic bacteria from the family of Thermoanaerobacteraceae.
Marinactinospora is a genus in the phylum Actinomycetota (Bacteria). It contains a single species, Marinactinospora thermotolerans. The species has a high tolerance for environmental temperatures, up to 55°C.
Akkermansia glycanphila is a species of intestinal mucin-degrading bacterium. It was first isolated from reticulated python feces in 2016.
