Bifidobacterium longum subsp. infantis strain TPY12-1 485

Bifidobacterium longum subsp. infantis strain TPY12-1 485 is a Gram-positive, nonsporulating rod-shaped bacterium that typically exists in pairs, clusters, or as single cells. This strain is an anaerobe, thriving in environments devoid of oxygen, which is characteristic of its habitat, primarily associated with host organisms, particularly in the gastrointestinal tract of infants. The optimal temperature for growth is around 37.0°C, aligning with the physiological conditions of its host. Given its anaerobic nature and association with the gut microbiota, Bifidobacterium longum subsp. infantis strain TPY12-1 485 plays a critical role in the digestion and fermentation of dietary fibers, contributing to the production of short-chain fatty acids that are beneficial for gut health. This strain's specific adaptations to its host-associated habitat suggest that it may have evolved mechanisms to efficiently utilize the nutrients available in the infant gut, providing insights into the co-evolution of gut microbiota and their hosts. Such interactions are essential for establishing a healthy microbiome during early life, underscoring the importance of this strain in the development of infant gut health and overall well-being.
