Coprothermobacterota

Coprothermobacterota is a phylum of nonmotile, rod-shaped bacteria.

Its members are strictly anaerobic and thermophilic, growing at optimal temperatures between 55 °C and 70 °C.

The name of this phylum is based on an early genus, dubbed "Coprothermobacter", a term whose etymology derives from the Greek words "kopros", meaning manure, and "thermos", warm, referring to the fact that these bacteria are capable of living at relatively high temperatures, with a maximum growth temperature of 75 °C.
