Fusobacterium polymorphum str. KCOM 1275 (=ChDC F310)

Fusobacterium polymorphum str. KCOM 1275 (=ChDC F310) is a Gram-negative, rod-shaped bacterium that typically arranges itself in pairs and is characterized as nonsporulating. As a chemoheterotroph, it derives its energy from organic compounds, which is consistent with its ecological niche within the gut of hosts. This strain thrives under anaerobic conditions, making it well-adapted to the oxygen-limited environment of the intestinal tract. Optimal growth occurs at 37.0°C, aligning with the physiological temperature of many warm-blooded animals. The presence of F. polymorphum in the host gut suggests that it may play a role in the complex microbial community associated with digestion and nutrient absorption. While the specific interactions and functions of this strain within the gut microbiome remain to be elucidated, its adaptation to anaerobic conditions and its position as a chemoheterotroph indicate that it may contribute to the fermentation processes that are essential for breaking down complex carbohydrates. Such metabolic activities can have implications for host health, including the production of short-chain fatty acids, which are important for maintaining gut integrity and overall metabolic functions. Further research is warranted to explore the specific roles and contributions of F. polymorphum in microbial ecosystems and host interactions.
