Bifidobacterium longum subsp. longum KACC 91563

Bifidobacterium longum subsp. longum KACC 91563 is a Gram-positive, obligately anaerobic, rod-shaped microbe that thrives in a temperature range of mesophilic to thermophilic conditions, with an optimal growth temperature of around 37°C (preferred temperature range: 20-45°C). This microbe is a chemoheterotroph, meaning it uses organic compounds as its energy source, and produces energy through the breakdown of complex molecules. Specifically, it ferments carbohydrates, such as sugars, to produce ATP and organic acids. The shape of Bifidobacterium longum subsp. longum KACC 91563 is characteristic of the genus, with a distinctive Y-shaped or V-shaped morphological feature. As a Gram-positive microbe, its cell wall composition is rich in peptidoglycan, which imparts its distinctive staining properties. This microbe is capable of colonizing various body sites, including the gut, respiratory tract, urogenital tract, and skin. In fact, it is one of the most abundant species in the human gut microbiome, where it plays a crucial role in maintaining a balanced ecosystem. Oxygen preference is another crucial aspect, as Bifidobacterium longum subsp. longum KACC 91563 is an obligate anaerobe, unable to grow in the presence of oxygen. This adaptation is likely a result of its evolution in the deep layers of the gut, where oxygen levels are limited. In addition to its physiological characteristics, Bifidobacterium longum subsp. longum KACC 91563 has been found to produce a range of bioactive compounds, including vitamins, polypeptides, and anticancer agents. Furthermore, research has implicated this species in the prevention of diseases such as inflammatory bowel disease, allergies, and cancer, making it a valuable target for further study and potential therapeutic applications.
