Adlercreutzia is a genus of obligately anaerobic, Gram-positive, non-spore-forming and non-motile bacteria in the family Eggerthellaceae. Cells are rod-shaped or coccobacillary, and species have been isolated from the intestinal tracts and feces of humans and other mammals.[2][3][4] The type species, A. equolifaciens, can convert isoflavones into equol.[2] The genus contains 13 species with validly published and correct names.[1]
Etymology
The generic name honours Herman Adlercreutz, formerly a professor at the University of Helsinki, for his contributions to research on the effects of phytoestrogens on human health.[1]
Taxonomy
A genome-based reclassification united Adlercreutzia, Asaccharobacter, Enterorhabdus and Parvibacter in 2018. Species from the latter three genera were transferred to Adlercreutzia, and their genus names were treated as heterotypic synonyms.[4][1]
The placement of Parvibacter caecicola is treated differently among taxonomic resources. Later genome analyses supported retaining it in Parvibacter because of its phylogenomic position and its distinction from other Adlercreutzia species.[5][6] LPSN nevertheless treats Adlercreutzia caecicola as the correct name and Parvibacter as a synonym of Adlercreutzia, whereas NCBI retains Parvibacter caecicola as the current name.[1][7]
Phylogeny
The nomenclature and species list below follow the List of Prokaryotic names with Standing in Nomenclature (LPSN), with the National Center for Biotechnology Information (NCBI) taxonomy database used as an additional reference.[1][8] The trees compare the 16S rRNA gene phylogeny from LTP_all_07_2026 with the genome-based phylogeny from GTDB release R11-RS232, which is based on 120 marker proteins.[9][10][11][12] Placeholder and uncultured taxa are omitted.

Adlercreutzia aquisgranensis, A. faecimuris and A. rubneri were not represented by species-labelled sequences in the LTP release and are omitted from the LTP tree. In GTDB R11-RS232, A. agrestimuris and A. aquisgranensis are placed in Xiamenia, A. caecicola in Parvibacter, A. faecimuris in Enterorhabdus, and A. murintestinalis in the placeholder genus "Adlercreutzia_A". Adlercreutzia hattorii does not appear as a separate species label in that release; these taxa are therefore omitted from the GTDB Adlercreutzia tree.[12]
