Bacteroides fragilis str. S23L17

Bacteroides fragilis strain S23L17 is a Gram-negative, rod-shaped bacterium that typically exists as single cells. This anaerobic organism thrives optimally at a temperature of 37.0°C, which aligns with the physiological conditions found within the human body, its primary habitat. As a chemoorganotroph, B. fragilis S23L17 utilizes organic compounds as its energy source, reflecting its adaptation to a host-associated environment where it likely engages in complex interactions with the host microbiome. Bacteroides fragilis is known for its role in the human gut, where it contributes to the fermentation of complex carbohydrates and the production of short-chain fatty acids, which are important for maintaining gut health. The presence of strain S23L17 in this specific microbial community may provide insights into its functional contributions, including potential modulation of immune responses or metabolic interactions with other gut microbes. Understanding the traits of this strain could enhance our knowledge of bacterial diversity in the human microbiome and its implications for health and disease.
