Bifidobacterium longum subsp. longum KACC 91563

Bifidobacterium longum subsp. longum KACC 91563 is a Gram-positive, anaerobic bacterium characterized by its rod shape and non-motile nature. This species typically arranges itself in clusters, pairs, or singles and thrives optimally at a temperature of 37°C, within a mesophilic temperature range. The bacterium is host-associated, indicating its presence in specific biological environments, and it exhibits a free-living biotic relationship. It possesses two replicons and a single membrane, which are notable traits for its cellular structure. The presence of flagella suggests a potential for motility, although Bifidobacterium longum subsp. longum KACC 91563 itself is non-motile. The bacterium's adaptations to anaerobic conditions highlight its ecological role in environments devoid of oxygen, such as the human gut, where it contributes to the microbiota's balance. In summary, Bifidobacterium longum subsp. longum KACC 91563 showcases essential traits that facilitate its survival and function within host-associated habitats. Its role as a free-living organism underscores its importance in maintaining gut health and overall ecological balance within the microbiome.
