The family caldicoprobacteraceae

Abstract

The family Caldicoprobacteraceae belongs to the order Clostridiales, phylum Firmicutes. It embraces the genus Caldicoprobacter which contains three recognized species: C. oshimai, C. algeriensis, and C. guelmensis, together with Acetomicrobium faecale which should be reclassified within the genus Caldicoprobacter as C. faecale, comb. nov. Members of the family are defined by a wide range of morphological and chemotaxonomic properties including the cellular fatty acids content. They are all strictly anaerobic thermophilic heterotrophic rod-shaped bacteria using sugars, but not proteinaceous compounds. Members of the family are found in herbivore feces and terrestrial hot springs.
