Bacteroides fragilis str. S36L11

Bacteroides fragilis strain S36L11 is a Gram-negative, rod-shaped bacterium that typically exists as single cells and exhibits anaerobic metabolism. This strain thrives optimally at a temperature of 37.0°C, which corresponds closely to the average human body temperature, suggesting its adaptation to a host-associated habitat. As a chemoorganotroph, B. fragilis str. S36L11 derives energy from organic compounds, highlighting its role in the digestion of complex carbohydrates within the host's gastrointestinal tract. The anaerobic nature of B. fragilis str. S36L11 indicates its significant ecological niche in environments devoid of oxygen, such as the human colon, where it contributes to the intricate balance of microbial communities. This bacterium plays a crucial role in the fermentation of dietary fibers and the production of short-chain fatty acids, which are beneficial for host health. Understanding the specific traits of Bacteroides fragilis str. S36L11 enhances our knowledge of its functional contributions to gut microbiota and its potential influences on host metabolism and immune responses.
