Families and genera

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]

Phylogeny[]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[3] and National Center for Biotechnology Information (NCBI)[1] and the phylogeny is based on 16S rRNA-based LTP release 111 by The All-Species Living Tree Project.[4]

The Thermoanaerobacterales, as previously mentioned, is polyphyletic, and consists of over six morphologically and physiologically similar clades:
