Bacteroides fragilis str. 3976T8

Bacteroides fragilis str. 3976T8 is a Gram-negative, rod-shaped bacterium classified as a chemoorganotroph, indicating its ability to derive energy from organic compounds. This microorganism is non-motile and does not possess flagella, which suggests a reliance on passive movement within its habitat. It typically exists in a single-cell arrangement and is categorized as an anaerobe, thriving in environments devoid of oxygen. The optimal temperature for B. fragilis str. 3976T8 growth is 37°C, placing it within the mesophilic temperature range, which is conducive to human body temperatures, hinting at its association with host environments. It is noted for having a single replicon and two membranes, which is characteristic of Gram-negative bacteria, contributing to its structural integrity and functionality in various ecological contexts. In terms of ecological relationships, B. fragilis str. 3976T8 is described as free-living, suggesting that it may play roles outside of symbiotic or pathogenic interactions, potentially contributing to the microbial diversity of its habitat. The presence of this organism in host-associated environments underscores its significance in the gut microbiome, where it may participate in complex interactions with other microbial species and influence host health. Understanding its traits can provide insights into its ecological role and potential applications in microbiome research. Accessions for this strain can be found under JGDS00000000.1.
