Project description:We used culturing of fecal sample enrichments on solid medium containing gastric mucin as the main carbon source to isolate a novel bacterium that is largely restricted to using the N-acetylglucosamine and N-acetylgalactosamine sugars from mucin. This butyrate-producing bacterium accesses these sugars from both polymeric gastric mucin and chemically released oligosaccharides and has a genome with correspondingly restricted carbohydrate-active enzyme content. Sequencing data was curated to determine gene expression profiles when comparing N-acetylgalactosamine, N-acetylglucosamine, gastric mucin oligosaccharides and cellobiose.
