Faecalibacterium prausnitzii strain CNCM I 4546

Faecalibacterium prausnitzii strain CNCM I 4546 is a Gram-positive, nonsporulating rod-shaped bacterium that acts as a chemoheterotroph, deriving its energy from organic compounds. This strain thrives optimally at a temperature of 37.0°C, suggesting its adaptation to warm-blooded hosts. As an anaerobe, F. prausnitzii strain CNCM I 4546 is capable of surviving and metabolizing in oxygen-deprived environments, which is characteristic of the gut microbiota where it is commonly found. The habitat of F. prausnitzii encompasses multiple environments, although it is predominantly associated with the gastrointestinal tract of humans and other mammals. Its presence in the gut is indicative of its potential role in maintaining intestinal health and stability, contributing to the complex microbial community. Notably, F. prausnitzii has garnered interest due to its association with beneficial effects on gut health, particularly in maintaining a balanced microbiome. Its ability to thrive in anaerobic conditions and utilize a range of organic substrates underscores its ecological versatility and importance within the digestive ecosystem. Further investigation into this strain could illuminate its specific interactions with host immune responses and its potential contributions to gut homeostasis.
