Lacticaseibacillus rhamnosus strain LR5

Lacticaseibacillus rhamnosus strain LR5 is a Gram-positive, rod-shaped bacterium classified as a facultative anaerobe. It thrives optimally at a temperature of 37°C and falls within the mesophilic temperature range. L. rhamnosus LR5 is characterized by the presence of flagella, although it is non-motile. This strain is free-living, which indicates it does not rely on a host for survival. L. rhamnosus LR5 is known to inhabit multiple environments and has been identified in association with a variety of hosts, including Homo sapiens (humans), Metazoa (multicellular animals), Capra hircus (domestic goats), and Panax ginseng (a medicinal plant). This wide range of hosts suggests that L. rhamnosus LR5 may play a significant role in various biological and ecological contexts, potentially contributing to gut health in humans and other animals. The bacterium possesses a single replicon and a single membrane, indicating a relatively simple cellular structure typical of many lactic acid bacteria. Notably, L. rhamnosus LR5 is nonsporulating, which means it does not form spores to survive adverse conditions. Instead, its adaptability as a facultative anaerobe allows it to thrive in both aerobic and anaerobic environments. Overall, Lacticaseibacillus rhamnosus strain LR5 exemplifies the ecological versatility of lactic acid bacteria, particularly in their interactions with diverse hosts and environments, highlighting their potential importance in both health and ecological balance.
