Thermoanaerobacterales
Scientific classification
Domain:	Bacteria
Phylum:	Bacillota
Class:	Clostridia; Rainey 2010
Order:	Thermoanaerobacterales; Wiegel 2010
Families and genera
	Thermoanaerobacteraceae; Zhaonellaceae;

The Thermoanaerobacterales is a polyphyletic order of bacteria placed within the polyphyletic class Clostridia, and encompassing four families: the Thermoanaerobacteraceae, the Thermodesulfobiaceae, the Thermoanaerobacterales Family III. Incertae Sedis, and the Thermoanaerobacterales Family IV. Incertae Sedis, and various unplaced genera.^[1]

This order is noted for the species' abilities to survive in extreme environments without oxygen and of relatively elevated temperatures for a living being (up to 80-90 °C). An example organism in this order is Thermoanaerobacter ethanolicus.^[2]

Taxonomy[edit]

The Thermoanaerobacterales, as previously mentioned, is polyphyletic, and consists of numerous morphologically similar clades:
