The Mycobacteriales are an order of bacteria. ^[1] The current description is genome-based, per Gupta 2019 emendation. Most members produce mycolic acids. ^[3]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN). ^[2]

Terminology

Mycolata has been used as a non-taxonomic term for mycolic acid-containing Actinobacteria. Mycobacteriales includes all such species, but it also includes some without mycolic acid, making these two terms imperfect, paraphyletic, aliases. ^[11]
