Lactobacillus johnsonii strain BS15

Lactobacillus johnsonii strain BS15 is a Gram-positive, rod-shaped bacterium that typically forms chains and is classified as a facultative anaerobe. This strain thrives optimally at a temperature of 25.0°C, suggesting a preference for relatively moderate environmental conditions. As a member of the Lactobacillus genus, L. johnsonii strain BS15 is predominantly host-associated, indicating its presence in various host organisms, which may include humans and animals. The facultative anaerobic nature of this strain allows it to adapt to varying oxygen levels, potentially enabling it to colonize diverse niches within the host. The ability to form chains may enhance its stability and persistence in the host environment, facilitating interactions with other microbial species and the host immune system. Overall, Lactobacillus johnsonii strain BS15 exemplifies the characteristics of a versatile microbe, capable of existing in diverse environments and contributing to the microbiota of host organisms. Its adaptation to moderate temperatures and facultative anaerobic metabolism may play a crucial role in its ecological interactions and functional contributions within the microbial community.
