The Nitriliruptoria are one of five classes of Actinobacteria, which contains four monotypic genera placed in separate orders.
The phylogeny is based on 16S rRNA-based LTP release 123 by 'The All-Species Living Tree' Project.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).
