Bifidobacterium adolescentis strain IVS-1

Bifidobacterium adolescentis strain IVS-1 is a Gram-positive, rod-shaped bacterium that thrives in anaerobic conditions, making it well-suited for environments within the intestines of various hosts. This strain is non-motile and does not produce flagella, emphasizing its adaptation to a stable habitat where mobility is less critical. It is classified as mesophilic, with an optimal growth temperature of 37°C, aligning with the typical conditions found in the gastrointestinal tracts of mammals. This strain has a single replicon and a single membrane, which is characteristic of many bacteria, particularly those within the Bifidobacterium genus. Notably, B. adolescentis IVS-1 is free-living, indicating it maintains a biotic relationship with its hosts, which include Homo sapiens, Bos taurus, Sus scrofa, and Oryctolagus cuniculus. This versatility in host range highlights its potential role in gut microbiota across different mammalian species. The absence of sporulation suggests that B. adolescentis IVS-1 is reliant on stable environmental conditions for survival and reproduction. Its presence in the guts of diverse mammals may contribute to digestive health and the maintenance of a balanced microbiome. Overall, this strain exemplifies the ecological significance of Bifidobacterium species in supporting gut health in various hosts, potentially influencing nutrient absorption and immune responses. Its adaptability to different mammalian hosts underscores the importance of microbial diversity in maintaining ecological balance within the gut ecosystem.
