Roseburia cecicolaRANK: SpeciesTAXONOMY: Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Lachnospiraceae -> Roseburia -> Roseburia cecicola OVERVIEW: Roseburia cecicola gen. nov., sp. nov., a motile, obligately anaerobic bacterium from a mouse cecum. Int. J. Syst. Bacteriol., 1983, 33, 618-627. Strain GMT cells were gram-negative, nonsporeforming, slightly curved rods (0.5 by 2.5 to 5 μm) with 20 to 35 flagella inserted into the concave side and, occasionally, into the end of each cell. The flagella appeared as a single fascicle when the cells were examined by phase-contrast microscopy. Glycerol, sorbitol, D-glucuronic acid, D-xylose, D-galactose, D-raffinose, D-glucose, D-maltose, cellobiose, sucrose, starch, and glycogen were growth substrates for this organism. Butyrate, ethanol, CO2, and H2 were products of fermentation of glucose and acetate by growing cells. The guanine-plus-cytosine content of the deoxyribonucleic acid of strain GMT was 42.3 mol%, as determined by the thermal denaturation method. |
