Dysosmobacter welbionis is a species of strictly anaerobic, non-spore-forming, Gram-negative-staining, rod-shaped bacterium in the genus Dysosmobacter , within the family Oscillospiraceae and order Eubacteriales. It was first isolated from human feces and formally described in 2020 by Le Roy et al. [1] The species name honors the Walloon Excellence in Life Sciences and BIOtechnology (WELBIO) program.
Dysosmobacter welbionis was isolated in 2017 from the feces of a healthy adult in Brussels, Belgium. The type strain J115T is held in the DSMZ and LMG culture collections. Phylogenetic analysis places the species within the family Oscillospiraceae, and it is considered part of the human gut microbiota.
Dysosmobacter welbionis is a non-motile, rod-shaped bacterium. Although it stains Gram-negative, it is phylogenetically related to Gram-positive clades. It is strictly anaerobic and mesophilic, with optimal growth at 37 °C. The species produces short-chain fatty acids, notably butyrate, through fermentation.
