Faecalibacterium prausnitzii

Definition

Anaerobic bacterium of the Firmicutes phylum, producing butyrate, a short-chain fatty acid major for intestinal health. It is one of the most abundant bacteria in the human microbiome.

How it works

Faecalibacterium prausnitzii represents 5-10% of the intestinal microbiome in healthy individuals. It ferments dietary fibers to produce butyrate, a short-chain fatty acid that feeds colon cells and reduces inflammation.

Role

Produces butyrate, a key molecule for the health and energy of intestinal cells

Examples

• Clusters IV and XIVa of Clostridium
• Firmicutes subgroup
• Major indicator of microbiome health

Recommendations

Consume a lot of soluble fibers (oats, barley, legumes, chicory) to nourish this essential bacterium. Specific prebiotics like inulin favor it particularly.

Key takeaway

Faecalibacterium prausnitzii is a major anti-inflammatory bacterium, restorable by a high-fiber diet
