Scientific classification
Domain:	Bacteria
Phylum:	Bacillota
Class:	"Halanaerobiia"
Order:	Halanaerobiales; corrig. Rainey and Zhilina 1995
Families

The Halanaerobiales are an order of bacteria placed within the class Clostridia, and encompassing two families, the Halanaerobiaceae and the Halobacteroidaceae. Originally placed within the highly polyphyletic class Clostridia, according to the NCBI and LPSN, it is now thought to lie outside the Bacillota.^{[citation needed]} Halanaerobiales are halophilic obligate anaerobes with a fermentative or homoacetogenic metabolism.^[1]
