Species

Romboutsia is a genus of Gram-positive-staining, spore-forming, obligately anaerobic bacteria in the family Peptostreptococcaceae. Cells are rod-shaped and inhabit the gastrointestinal tract of mammals, where they ferment diverse carbohydrates and participate in bile acid transformations. [1] [2]

Contents

Etymology

The genus name honours Dutch microbiologist Frans M. Rombouts for his contributions to food microbiology and probiotic research. [1]

Taxonomy and characteristics

Phylogenetic analysis of 16S rRNA genes and whole-genome data places Romboutsia within the class Clostridia, distinct from the polyphyletic ‘‘Clostridium’’ sensu lato group. Comparative genomics of the type strain Romboutsia ilealis CRIBT (R. ilealis) reveals extensive adaptation to the small intestine, including genes for bile-salt tolerance and rapid carbohydrate uptake. [3]

Recognised species (alphabetical order):

Cells are catalase-negative rods with oval, subterminal spores. Optimal growth occurs at 37°C on complex media containing 0.5–2 % bile salts.
