Fusobacterium polymorphum strain KCOM 1274 (=ChDC F309) F309_53

Fusobacterium polymorphum strain KCOM 1274 (=ChDC F309) F309_53 is a Gram-negative, rod-shaped bacterium that typically exists in pairs and is classified as a nonsporulating organism. This strain thrives in anaerobic conditions, reflecting its adaptation to environments devoid of oxygen, such as the gut of its host. It is a chemoheterotroph, utilizing organic compounds as both a carbon and energy source, which is characteristic of many gut-associated microbes that contribute to the complex dynamics of the intestinal microbiome. Optimal growth of F. polymorphum strain KCOM 1274 occurs at 37.0°C, which aligns with the physiological temperature of mammalian hosts, facilitating its role as a gut inhabitant. The presence of this bacterium in the host gut underscores its potential involvement in various metabolic processes, including the fermentation of dietary components and the modulation of gut health. This strain exemplifies the diverse microbial life within the intestinal ecosystem, where anaerobic bacteria play critical roles in digestion and nutrient absorption. The specific ecological niche occupied by F. polymorphum strain KCOM 1274 highlights the importance of understanding how such anaerobes interact with host physiology and the broader microbial community, potentially influencing health outcomes through their metabolic activities.
