Faecalibacterium prausnitzii str. CNCM I 4540

Faecalibacterium prausnitzii str. CNCM I 4540 is a Gram-positive, non-sporulating rod-shaped bacterium that thrives optimally at 37.0°C. As a chemoheterotroph, this microbe relies on organic compounds for energy, making it well-suited to diverse habitats, particularly within the human gut microbiota. F. prausnitzii is strictly anaerobic, indicating that it grows in environments devoid of oxygen, which is characteristic of the anaerobic conditions found in the intestinal tract. This strain is notable for its role within the gut ecosystem, where it contributes to maintaining intestinal health and homeostasis. The presence of F. prausnitzii has been associated with beneficial effects on gut health, including anti-inflammatory properties, suggesting its importance in the overall microbial balance and functionality of the intestinal microbiome. The unique ability of this bacterium to thrive in anaerobic environments while utilizing a range of organic substrates underscores its ecological adaptability and potential implications for gut health.
