Lactobacillus gasseri strain PSS7772D

Lactobacillus gasseri strain PSS7772D is a Gram-positive, rod-shaped bacterium characterized by its non-motility and presence of flagella. This strain typically exists in chains or as single cells and exhibits a facultative anaerobic oxygen requirement, allowing it to thrive in varying oxygen conditions. It is classified as mesophilic, with an optimal growth temperature of 25°C, but it can grow within a broader temperature range suitable for mesophilic organisms. This strain is host-associated, specifically found in Homo sapiens, indicating a potential role in the human microbiome. Lactobacillus gasseri strains are often studied for their probiotic properties, contributing to gut health and influencing the host's immune response. PSS7772D is free-living, meaning it can exist independently rather than being reliant on a specific host environment. Importantly, L. gasseri strain PSS7772D is non-sporulating and contains one replicon and one membrane. Its genetic information is cataloged under the accession number LRQD00000000.1, which aids in further studies and understanding of its specific traits and functions. The presence of Lactobacillus gasseri in the human gut highlights its ecological significance, as it may play a role in maintaining a balanced microbiota and supporting digestive health. This relationship underscores the importance of such microbes in human physiology and their potential application in probiotics and health-related products.
