Scientific classification
Kingdom: Bacteria
Phylum: Firmicutes
Class: Clostridia Rainey 2010
Order: Thermoanaerobacterales Wiegel 2010
Family: Thermodesulfobiaceae Mori et al. 2004

The family Thermodesulfobiaceae according to the LPSN is located within the order Thermoanaerobacterales and class Clostridia. However, according to the All-Species Living Tree Project it lies outside the clade Firmicutes and the genus Caldanaerovirga does not belong to the clade, i.e. Thermodesulfobiaceae is polyphyletic.


The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI)[2] and the phylogeny is based on 16S rRNA-based LTP release 111 by The All-Species Living Tree Project [3]
