Asaccharobacter celatus
Asaccharobacter celatus is a Gram-positive, non-spore-forming and obligately anaerobic bacterium from the genus of Asaccharobacter which has been isolated from a rat caecum in Japan. Asaccharobacter celatus produces equol and 5-hydroxy equol.
In 2018, the genus Asaccharobacter was transferred into the genus Adlercreutzia based on branching patterns observed in phylogenetic trees. The correct nomenclature is Adlercreutzia ''equolifaciens subsp. celatus.''
