Bifidobacterium adolescentis strain AL12-4

Bifidobacterium adolescentis strain AL12-4 is a Gram-positive, anaerobic bacterium characterized by its rod shape and non-motility. This strain is free-living and has been identified in various host species, including humans (Homo sapiens), cattle (Bos taurus), pigs (Sus scrofa), and rabbits (Oryctolagus cuniculus). It exhibits a single cell arrangement and does not form spores. The optimal growth temperature for Bifidobacterium adolescentis strain AL12-4 is 37 degrees Celsius, placing it within the mesophilic temperature range. This temperature preference aligns with the typical conditions found in warm-blooded hosts, where it is likely to thrive. The organism has a single replicon and a single membrane, characteristics that are common among certain members of the Bifidobacterium genus. The presence of flagella suggests potential motility mechanisms; however, this strain is classified as non-motile, indicating that it does not actively swim. Its anaerobic nature implies that it thrives in environments devoid of oxygen, which is typical for many gut-associated microbiota. Bifidobacterium adolescentis strain AL12-4 may play a role in the gut microbiota of its host species, contributing to digestive health and the maintenance of microbial balance. Its ability to inhabit diverse animals suggests a potentially significant ecological role in various gastrointestinal environments, illustrating the bacterium’s adaptability and importance in the microbiome of different hosts.
