Table 1 Functions of commensal bacteria in the gut
| Protective functions Pathogen displacement Competition for nutrients Competition for receptors Production of anti-microbial factors |
| Metabolic functions Fermentation of non-digestible dietary substances Generation of short chain fatty acids Salvage of energy source Synthesis of essential vitamins (vitamin K and B12, niacin, biotin and folate) |
| Structural functions Regulation of epithelial cell turnover Promotion of epithelial cell differentiation Fortification of epithelial barrier Stabilization of tight junctions |
| Immune functions Induction of secretory IgA Induction of oral tolerance Shaping of immune microenvironment |
