Anaerobutyricum is a genus of Gram-positive, anaerobic, rod-shaped bacteria in the family Lachnospiraceae. These bacteria are important members of the gut microbiota and are known for their ability to produce short-chain fatty acids such as butyrate and propionate through the fermentation of dietary substrates.
Taxonomy
The genus was established in 2018 when Eubacterium hallii was reclassified as Anaerobutyricum hallii, and a new species, Anaerobutyricum soehngenii, was described.[1] The classification was based on genomic and phenotypic differences that justified separation from the polyphyletic genus Eubacterium.
As of now, the genus comprises two recognized species:
- Anaerobutyricum hallii – formerly Eubacterium hallii
- Anaerobutyricum soehngenii
Ecology and physiology
Species of Anaerobutyricum are typically isolated from human or infant feces, where they play a role in fermenting carbohydrates and organic acids. They are non-spore-forming and non-motile, and grow under strictly anaerobic conditions.
