Faecalibacterium prausnitzii str. CNCM I 4544

Faecalibacterium prausnitzii str. CNCM I 4544 is a Gram-positive, nonsporulating, rod-shaped bacterium that thrives as an anaerobe, with an optimal growth temperature of 37.0°C. This organism exhibits chemoheterotrophic metabolic capabilities, utilizing organic compounds as energy sources. F. prausnitzii is typically found in various habitats, particularly within the human gastrointestinal tract, where it plays a significant role in maintaining gut health and homeostasis. Its presence is often associated with a balanced intestinal microbiota, suggesting its potential importance in various physiological functions, including the modulation of immune responses and the production of short-chain fatty acids, which are beneficial to host health. Given its anaerobic nature and optimal temperature, F. prausnitzii str. CNCM I 4544 exemplifies the physiological adaptations of gut microbiota to the anaerobic, warm environment of the intestines. This specialized niche and its metabolic strategies may contribute to its role in preventing dysbiosis and supporting metabolic health in the host. Understanding the traits of this strain could provide insights into its functionality within complex microbial communities and its potential implications for gut health.
