Bacteroides fragilis str. Korea 419

Bacteroides fragilis str. Korea 419 is a Gram-negative, rod-shaped bacterium that typically exists as single cells. This strain is classified as an anaerobic chemoorganotroph, thriving in environments where oxygen is limited. Its optimal growth temperature is 37.0°C, which aligns with the physiological conditions of its host-associated habitat. Bacteroides fragilis, as a member of the Bacteroidetes phylum, plays a significant role in the microbiota of the human gut, contributing to the breakdown of complex polysaccharides and fostering a balanced microbial ecosystem. The anaerobic nature of this strain suggests it is well-adapted to the oxygen-free environments found within the intestines, where it can utilize organic compounds for energy. The ability of Bacteroides fragilis str. Korea 419 to thrive in association with host organisms highlights its potential importance in maintaining gut health and influencing host metabolism. The interactions between this bacterium and its host may provide insights into the complex dynamics of gut microbiota and their contributions to digestive processes and overall health. Understanding the specific traits of this strain could further elucidate its role in the microbe-host relationship, especially in terms of nutrient acquisition and metabolic functions within anaerobic environments.
