Ligilactobacillus salivarius DSM 20555 = ATCC 11741

Ligilactobacillus salivarius DSM 20555, also known as ATCC 11741, is a Gram-positive bacterium characterized by its rod shape and non-motile nature. This species is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. Its optimal growth temperature is 45°C, placing it within the mesophilic temperature range. Ligilactobacillus salivarius is host-associated, indicating a biotic relationship that typically involves free-living interactions. This organism has a single replicon and a single membrane, and it does not undergo sporulation, which may suggest a stable lifestyle within its ecological niche. The presence of flagella, despite its non-motile status, suggests that it may have the potential for movement under certain conditions, although it does not actively swim. Understanding the ecological role of Ligilactobacillus salivarius could provide insights into its function within host-associated microbial communities. Its ability to thrive at elevated temperatures may enable it to colonize specific niches in the host that experience higher temperatures, such as the gastrointestinal tract under certain conditions. This adaptability could make it a significant player in the gut microbiome, contributing to digestion and overall host health.
