Thermoanaerobacterales

Order of bacteria From Wikipedia, the free encyclopedia

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

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