Bacteroides fragilis str. 3783N1-6

Bacteroides fragilis str. 3783N1-6 is a Gram-negative, rod-shaped bacterium classified as a chemoorganotroph, utilizing organic compounds for energy. This strain is characterized by its anaerobic metabolism, thriving in environments devoid of oxygen. Bacteroides fragilis str. 3783N1-6 is non-motile and exhibits a cell arrangement of singles, lacking the ability to form clusters. The strain possesses a single replicon and is surrounded by two membranes, a trait common among Gram-negative bacteria. It has an optimal growth temperature of 37°C, categorizing it as mesophilic, which is typical for many host-associated microorganisms. Its habitat is primarily host-associated, indicating a potential role in symbiotic relationships within the microbiota. One notable aspect of Bacteroides fragilis str. 3783N1-6 is its free-living biotic relationship, suggesting that while it may occur in a host environment, it can also survive independently. This characteristic may contribute to its ecological flexibility, allowing it to adapt to various environments within the gastrointestinal tract. Overall, the traits of Bacteroides fragilis str. 3783N1-6 highlight its importance in anaerobic environments, particularly in the human gut, where it plays a role in the complex microbial community. Its ability to thrive in a mesophilic range and its chemoorganotrophic metabolism underscore its ecological significance in nutrient cycling and maintaining gut health.
