This study shows that intestinal Bacteroides species degrade tryptophan into indoles, which enhance anti-tumor immunity and limit melanoma growth.

This study identifies the enzymatic pathway used by Bacteroides thetaiotaomicron to degrade colonic mucin O-glycans and shows that multiple exo-acting enzymes are critical for gut colonization.

This study identifies the group B [FeFe]-hydrogenase as the primary enzyme driving fermentative H2 production in the human gut, linking it to gut health and disease.

This study identifies Ruminococcus torques as a keystone mucin-degrading bacterium that releases oligosaccharides accessible to Bacteroides thetaiotaomicron, linking its role to inflammatory bowel disease.

This study shows that Akkermansia muciniphila increases susceptibility to a gut pathogen under fiber-deprived conditions but reduces pathogen load on a fiber-sufficient diet.
