, 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.

Notes

In October 2021, the name of this phylum has been accepted as ''validly published'', according to the emendations of the rules of the

International Code of Nomenclature of Prokaryotes The International Code of Nomenclature of Prokaryotes (ICNP) or Prokaryotic Code, formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC), governs the scientific names for Bacteria and Archaea.P.
