Bifidobacterium longum strain APC1461

Bifidobacterium longum strain APC1461 is a Gram-positive, anaerobic rod-shaped bacterium that typically forms clusters, pairs, or singles. This strain is nonsporulating and thrives optimally at a temperature of 37.0°C, an environment commonly associated with mammalian hosts. Bifidobacterium longum is known for its presence in the gastrointestinal tract of humans and other animals, where it plays a significant role in maintaining gut health. As a member of the gut microbiota, Bifidobacterium longum strain APC1461 contributes to the fermentation of dietary fibers and the production of short-chain fatty acids, which are crucial for maintaining intestinal health and regulating immune responses. The ability of this strain to survive and flourish in anaerobic conditions highlights its adaptation to the unique environment of the gastrointestinal tract, where oxygen levels are significantly lower than in other biological contexts. The presence of Bifidobacterium longum strain APC1461 in host-associated habitats suggests its involvement in symbiotic relationships within the gut microbiome, potentially aiding in digestion and nutrient absorption. Moreover, its optimal growth temperature aligns with the physiological conditions of the human body, indicating its evolutionary adaptation to life as a gut commensal. Understanding the specific roles and interactions of this strain within the gut ecosystem may provide insights into its contributions to host health and the microbiome's overall stability.
