Coprothermobacteraceae Coprothermobacteraceae is a new bacterial family of rod-shaped microorganisms, belonging to the order Coprothermobacterales, class Coprothermobacteria of the new phylum Coprothermobacterota. The name of this family was given on the basis of an ...

within the phylum

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 ...

mesophilic A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from . The optimum growth temperature for these organisms is 37°C. The term is mainly applied to microorganisms. Organi ...

anaerobic reactor used for the treatment of protein-rich wastewater from a baker's yeast factory, in Uruguay (region bounded by the ''Rio de la Plata'' river, giving rise to the name ''"platensis"'' for this species, though this bacterium was not isolated from the river).
