Roseburia is a genus of obligately anaerobic, butyrate-producing bacteria in the family Lachnospiraceae.[1] Members of the genus occur in the gastrointestinal tracts of mammals, and several species are common constituents of the human gut microbiota.[2] Cultured species are generally saccharolytic, motile rods that ferment carbohydrates and form butyrate as a major product.[3][2]
Taxonomy
[edit]The type species, Roseburia cecicola, was isolated from the cecum of a mouse.[4] The generic name honours the American microbiologist Theodor Rosebury, who studied microorganisms associated with humans.[1]
The List of Prokaryotic names with Standing in Nomenclature recognizes nine species with validly published and correct names in the genus.[1]
Biology and metabolism
[edit]Described Roseburia cells are straight or slightly curved rods. Many strains are motile by means of multiple flagella. The Gram-stain reaction has been reported as positive, negative, or variable among cultured strains, despite the phylogenetic placement of the genus within the phylum Bacillota.[3][2]
Species differ in their capacity to use dietary carbohydrates. Comparative genomic analysis has identified differences in carbohydrate-active enzymes and biosynthetic pathways among species, which may contribute to their occupation of different ecological niches in the colon.[5] Roseburia intestinalis, for example, can act as a primary degrader of dietary β-mannans, while Roseburia inulinivorans can use inulin.[6][2]
During carbohydrate fermentation, some strains consume acetate while producing butyrate.[3] Butyrate is used as an energy source by colonic epithelial cells and participates in metabolic and immune signalling in the intestine.[7]
Research
[edit]Differences in the relative abundance of Roseburia have been reported in observational studies of inflammatory bowel disease, colorectal cancer, and metabolic disorders.[8]
R. intestinalis has been investigated as a potential live biotherapeutic. Administration of the bacterium reduced inflammatory pathology and altered immune responses in experimental models of colitis, but these findings were obtained in preclinical systems.[9]
The relative abundance of R. inulinivorans was positively associated with several measures of muscle strength in human cohorts. Oral supplementation with the species also increased forelimb grip strength in antibiotic-treated mice and was accompanied by changes in amino-acid availability, muscle metabolism, and muscle-fibre composition.
