Bacteroides fragilis str. 3976T8

Bacteroides fragilis strain 3976T8 is a Gram-negative, rod-shaped bacterium that typically exists as single cells and is classified as an anaerobe, thriving optimally at a temperature of 37.0°C. This strain is a chemoorganotroph, indicating that it derives energy from organic compounds, which is consistent with its habitat as a host-associated microbe. Bacteroides fragilis is known to inhabit the gastrointestinal tract of various hosts, where it plays a significant role in the complex microbial ecosystem. Its adaptation to anaerobic conditions suggests that it participates in fermentation processes, contributing to the breakdown of complex polysaccharides into simpler compounds that can be utilized by both the bacterium and its host. The presence of Bacteroides fragilis strain 3976T8 in the gut microbiome underscores its potential involvement in nutrient metabolism and maintenance of gut health. By processing dietary fibers and producing short-chain fatty acids, this strain may help modulate host immune responses and maintain intestinal homeostasis. Further exploration of this strain's metabolic pathways could provide insights into its specific contributions to host nutrition and health.
