Faecalibacterium prausnitzii strain CNCM I 4541

Faecalibacterium prausnitzii strain CNCM I 4541 is a Gram-positive, non-motile, rod-shaped bacterium that plays a significant role in the gut microbiome of various habitats. As a chemoheterotroph, it derives energy from organic compounds, thriving in anaerobic conditions. This strain is mesophilic, with an optimal growth temperature of 37°C, which aligns with the typical temperature of the human body. The strain CNCM I 4541 is characterized by its single replicon and is non-sporulating, which indicates a reliance on stable environmental conditions for survival and growth. Its lack of mobility and presence of flagella highlight its adaptation to a specific ecological niche where movement is not essential for its lifestyle. Ecologically, Faecalibacterium prausnitzii is known for its beneficial effects on gut health, often linked to anti-inflammatory properties. The strain's ability to thrive in anaerobic environments and its role as a chemoheterotroph suggest its involvement in complex microbial interactions within the gut ecosystem. This highlights the importance of understanding such strains in the context of human health and disease, particularly in relation to gut microbiota composition and function.
