Fusobacterium polymorphum str. KCOM 1271 (=ChDC F305)

Fusobacterium polymorphum str. KCOM 1271 (=ChDC F305) is a Gram-negative, rod-shaped bacterium that typically arranges itself in pairs and is classified as a nonsporulating organism. This strain thrives optimally at a temperature of 37.0°C, indicating its adaptation to a host-associated environment, and it primarily utilizes a chemoheterotrophic metabolism for energy. As an anaerobe, F. polymorphum str. KCOM 1271 resides in the gut of its host, where oxygen levels are low, allowing it to flourish in this specialized habitat. The bacterium's nonsporulating nature suggests that it relies on other survival strategies in the absence of adverse environmental conditions. Its presence in the gut highlights its potential role in the complex microbial ecosystem, where it may interact with other gut microbiota and contribute to various metabolic processes. Moreover, the pairing of cells may facilitate specific interactions or functions within the gut, possibly influencing community dynamics or nutrient cycling. Understanding the traits of F. polymorphum str. KCOM 1271 provides insight into its potential ecological roles in the gut microbiome, including its contributions to digestion and metabolic exchanges within a host-associated anaerobic environment.
