coprothermobacterales coprothermobacterales coprothermobacterales is a taxonomic order of thermophilic bacteria in the class coprothermobacteria of the phylum coprothermobacterota. coprothermobacterales scientific classification domain: bacteria phylum: coprothermobacterota class: coprothermobacteria order: coprothermobacteralespavan et al. 2018 family coprothermobacteraceae its name derives from the type genus of this order, coprothermobacter, with the ending suffix '-ales', to denote an order. the bacteria of this order have a rod-shaped morphology, do not produce spores, are nonmotile, strictly anaerobic and, being thermophiles, grow at temperature ranges above 35°c and below 70°c, for a ph between 5.0 and 9.4. moreover, these bacteria are chemoorganotrophs and proteolytic fermenters, which produce acetic acid, h2, and co2 as main end-products of fermentation.
