Roseburia intestinalis

RANK: Species

TAXONOMY: Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Lachnospiraceae -> Roseburia -> Roseburia intestinalis


Roseburia intestinalis is a saccharolytic, butyrate-producing bacterium first isolated from human feces. It is anaerobic, gram-positive, slightly curved rod-shaped and motile by means of multiple subterminal flagella. Roseburia favors and loves starches that escape small intestinal degradation and RS3, cooked-cooled starches. R. intestinalis works synergistically often with Bifidobacteria. Very low carbohydrate diets can cause Roseburia counts to drop, which can cause butyrate to drop as well. Chitin and beta-glucan encourage Roseburia. (as does low dose RS2, green banana flour or RPS). High dose RS2 however will decrease Roseburia (Tachon /2013). Lower concentrations in Type II diabetics.

This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
