Ligilactobacillus salivarius strain DJ-sa-01

Ligilactobacillus salivarius strain DJ-sa-01 is a Gram-positive, rod-shaped bacterium that operates as a facultative anaerobe, capable of thriving in both aerobic and anaerobic conditions. This strain is characterized by a single membrane and does not form spores, indicating its reliance on stable environmental conditions for survival. The optimal growth temperature for L. salivarius DJ-sa-01 is 45°C, placing it within the mesophilic temperature range. This bacterium is non-motile, lacking flagella, which suggests a lifestyle that may be closely associated with its host environments rather than active movement through different habitats. It is free-living, indicating that it exists independently without requiring a specific host for its lifecycle, although it has been identified in various hosts, including Homo sapiens, Gallus gallus (chickens), Sus scrofa (pigs), and Aves (birds). The presence of Ligilactobacillus salivarius in diverse species highlights its potential ecological role as a beneficial microorganism in various gut microbiomes. Its association with both mammals and birds suggests a versatile adaptability and may indicate its importance in digestive health and microbial balance within these hosts. Given its ability to thrive across multiple environments, L. salivarius DJ-sa-01 could play a significant role in the maintenance of gut health and the overall microbial ecosystem of its hosts. This strain contributes to our understanding of the complex interactions within host-associated microbiomes and underscores the importance of microbial diversity in health and disease.
