Bacteroides fragilis str. 3-F-2 #6

Bacteroides fragilis str. 3-F-2 #6 is a Gram-negative, rod-shaped bacterium that thrives in host-associated environments. As a chemoorganotroph, it derives energy from organic compounds, which is typical for organisms inhabiting the gut of various hosts. This species is classified as an anaerobe, meaning it thrives in environments devoid of oxygen. Bacteroides fragilis str. 3-F-2 #6 is characterized by its cell arrangement of singles and is non-motile, despite the presence of flagella. The organism has an optimal growth temperature of 37°C, which aligns with the average body temperature of many mammals, suggesting a strong adaptation to its host-associated habitat. It operates within a mesophilic temperature range, indicating that it prefers moderate temperatures for growth. The bacterium contains a single replicon and has a cellular architecture featuring two membranes, which is characteristic of Gram-negative bacteria. In terms of its ecological role, Bacteroides fragilis str. 3-F-2 #6 is free-living, contributing to the microbial ecosystem in the gut. Its presence is significant as it likely participates in the complex interactions that occur within the gut microbiome, aiding in digestion and influencing host health. Overall, the traits of Bacteroides fragilis str. 3-F-2 #6 underscore its specialized adaptation to a host-associated lifestyle and its potential role in maintaining gut homeostasis.
