''Adlercreutzia'' is a genus in the phylum
Actinomycetota
The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. They can be terrestrial or aquatic. They are of great importance to land flora because of their contributions to soil systems. In soil t ...

Etymology
The generic name derives from H. Adlercreutz, a professor at the
University of Helsinki
The University of Helsinki (, ; UH) is a public university in Helsinki, Finland. The university was founded in Turku in 1640 as the Royal Academy of Åbo under the Swedish Empire, and moved to Helsinki in 1828 under the sponsorship of Alexander ...

phytoestrogens
A phytoestrogen is a plant-derived xenoestrogen (a type of estrogen produced by organisms other than humans) not generated within the endocrine system, but consumed by eating plants or manufactured foods. Also called a "dietary estrogen", it i ...

Taxonomy
In 2018, Nouioui ''et al.'' proposed merging the genera ''
Asaccharobacter,
Enterorhabdus'' and ''
Parvibacter'' within the genus ''Adlercreutzia'' based on observed clustering of these genera within phylogenetic trees.
However, subsequent phylogenetic analyses observed that ''Parvibacter caecicola'' exhibited much deeper branching compared to other ''Adlercreutzia'' species.
Additionally, five
conserved signature indels
Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. CSIs, brought about by rare genetic changes, provide useful phylogenetic markers ...
(CSIs) present in the proteins excinuclease ABC subunit UvrA, flavodoxin-dependent (E)-4-hydroxy-3-methylbut-2-enyl-diphosphate synthase,
phosphoribosylformylglycinamidine synthase,
valine-tRNA ligase and
cysteine–tRNA ligase were identified to be exclusively shared by all ''Adlercreutzia'' species with the exception of ''P. caecicola.''
Thus, the emended description of the genus ''Adlercreutzia'' is the same as given before, with the exclusion of ''P. caecicola'', which has been transferred back into the genus ''Parvibacter.''
