Thermoanaerobacteriales
Scientific classification
Kingdom: Bacteria
Division: Firmicutes
Class: Clostridia Rainey 2010
Order: Thermoanaerobacterales Wiegel 2010
Families

The Thermoanaerobacteriales are a polyphyletic order of bacteria placed within the polyphyletic class Clostridia, and encompassing three families: the Thermoanaerobacteraceae, the Thermodesulfobiaceae, Thermoanaerobacterales Family III. Incertae Sedis and various unplaced genera. This order is noted for the species abilities to survive in environments of extreme elevated temperature. An example organism in this order is Thermoanaerobacterium autearoensis.[1]

Phylogeny[edit]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [2] and National Center for Biotechnology Information (NCBI)[3] and the phylogeny is based on 16S rRNA-based LTP release 111 by The All-Species Living Tree Project [4]

The Thermoanaerobacteriales as previously mentioned are polyphyletic, and consist of over six morphologically and physiologically similar clades:
