Mucin‐degrading bacteria are known to be beneficial for gut health. We aimed to isolate human‐derived mucin‐degrading bacteria and identify potential probiotic characteristics and their effects on the bacterial community and short‐chain fatty acid (SCFA) production according to three different enterotypes of the host.

Bacteria with mucin decomposition ability from human faeces were isolated and identified by 16S rRNA sequencing and MALDI‐TOF. Heat resistance, acid resistance, antibiotic resistance, and antibacterial activity were analysed in the selected bacteria. Their adhesion capability to the Caco‐2 cell was determined by scanning electron microscopy. Their ability to alter the bacterial community and SCFA production of the isolated bacteria was investigated in three enterotypes. The three isolated strains were Bifidobacterium(Bif.) animalis …
