Taxonomy

Until the 2021 revision of bacterial taxonomy by the ICSP,^[4] the entire phylum was classified within the Proteobacteria (synonym Pseudomonadota) as the Epsilonproteobacteria and the Desulfurellales.^[5] The separation of this phylum from "Proteobacteria" was originally proposed in 2017, using GTDB-based methods.^[2]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)^[6] and National Center for Biotechnology Information (NCBI).^[7]

16S rRNA based LTP_10_2024[8][9][10]

120 marker proteins based GTDB 09-RS220[11][12][13]
