Bifidobacterium longum subsp. infantis str. BT1

Bifidobacterium longum subsp. infantis str. BT1 is a Gram-positive, rod-shaped bacterium that typically exists in clusters, pairs, or as single cells. This strain is classified as an anaerobe, thriving in environments devoid of oxygen, which aligns with its natural habitat associated with hosts, such as the gastrointestinal tract of infants. The optimal growth temperature for B. longum subsp. infantis str. BT1 is approximately 37.0°C, reflecting its adaptation to the warm environment of the human body. Bifidobacterium longum subsp. infantis plays a significant role in the gut microbiota, particularly during early life, where it contributes to the development of the immune system and digestion of human milk oligosaccharides. Its presence is crucial for maintaining gut health and homeostasis in infants. Notably, the ability of this strain to form various cell arrangements may enhance its adaptability and functionality within the complex microbial communities of the host's gut. In conclusion, Bifidobacterium longum subsp. infantis str. BT1 exemplifies a specialized adaptation to the host-associated environment, where its anaerobic nature and optimal growth temperature foster a symbiotic relationship, ultimately supporting the health and development of its human host.
