Halanaerobiales
Order of bacteria
From Wikipedia, the free encyclopedia
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.[3]
