Bacteroides fragilis str. S23L17

Bacteroides fragilis str. S23L17 is a Gram-negative, rod-shaped bacterium that is classified as an anaerobe, meaning it thrives in environments devoid of oxygen. This species is a chemoorganotroph, utilizing organic compounds as its energy source. It primarily exists in a free-living state, suggesting it can adapt to specific environments associated with hosts. The bacterium's cell arrangement is characterized by singles, indicating that it does not form clusters or chains. Bacteroides fragilis str. S23L17 is mesophilic, with an optimal growth temperature of 37°C, which aligns with the typical temperature of the human body, potentially reflecting its ecological niche within host-associated environments. This strain possesses a unique cellular structure, containing two membranes and a single replicon. Notably, it has flagella, which may contribute to its motility, although it is described as non-motile in the context provided. The ecological insight into Bacteroides fragilis str. S23L17 highlights its role in the microbiome of host organisms, where it may be involved in various biochemical processes, including the breakdown of complex carbohydrates. Its adaptation to anaerobic environments and its ability to utilize organic matter can have significant implications for host health, contributing to nutrient absorption and maintaining a balanced microbiota. The accession number for this strain is JHEF00000000.1, which allows for further genomic exploration and understanding of its functional capabilities.
