Resumen:
Rod-shaped cells, 0.5 × 1.0?6.0 μm; occur singly or in pairs in young cultures; pleomorphic in old cultures. Colonies are white, circular (diameter 1-2 mm), convex, smooth with entire edges. Stains Gram-negative. Non-spore-forming. Non-motile. Strictly anaerobic. Thermophilic. Optimum growth temperature, 55?70 °C. Neutrophilic. Chemoorganotrophic. Proteolytic, uses gelatin and peptones. Sugars are used poorly unless yeast extract or rumen fluid are added. Trypticase peptone stimulates glucose utilization. The main end products of sugar or protein fermentation are acetic acid, H2, and CO2. Thiosulfate, but not sulfate, is used as electron acceptor for growth. Dominant in thermophilic anaerobic digesters, also present in marine and terrestrial environments. Microorganisms of the genus Coprothermobacter represent one of the primary lines of descent in the bacterial domain.
