Bacteroides fragilis str. S6L5

Bacteroides fragilis str. S6L5 is a rod-shaped, Gram-negative bacterium that thrives in anaerobic environments, particularly associated with host organisms. This strain exhibits a singular arrangement of cells and is classified as a chemoorganotroph, utilizing organic compounds as its energy source. The optimal growth temperature for B. fragilis str. S6L5 is approximately 37.0°C, aligning with the physiological temperature of mammals, which suggests its adaptation to a host-associated habitat, likely within the gastrointestinal tract. The strict anaerobic nature of B. fragilis str. S6L5 indicates that it cannot survive in the presence of oxygen, which is a common characteristic of many gut microbiota that play pivotal roles in digestion and metabolism. This microbe is part of a broader community of anaerobes that contributes to the complex ecosystem of the human gut, participating in processes such as the fermentation of dietary fibers and the production of short-chain fatty acids, which are beneficial for host health. Understanding the traits of Bacteroides fragilis str. S6L5 can provide valuable insights into its ecological role in the microbiome, particularly in maintaining gut health and homeostasis. The relationship between this bacterium and its host underscores the intricate dependencies that define host-microbe interactions, highlighting its potential importance in digestive health and metabolic processes.
