Lactobacillus johnsonii NCC 533

Lactobacillus johnsonii NCC 533 is a Gram-positive bacterium that is classified as a facultative anaerobe and is rod-shaped. This organism typically exists in chains and is known to be free-living, meaning it does not have a pathogenic relationship with its host. It has a single membrane and a single replicon, which is characteristic of its bacterial structure. The optimal growth temperature for Lactobacillus johnsonii NCC 533 is around 25°C, placing it within the mesophilic temperature range. The organism does not exhibit mobility, and it possesses flagella, although its motility is restricted. Lactobacillus johnsonii NCC 533 is part of a broader group of lactic acid bacteria that are commonly found in various host-associated habitats, including the gastrointestinal tracts of animals and humans. This species is not associated with disease, indicating its potential role in promoting gut health and maintaining intestinal microbiota balance. Ecologically, the presence of Lactobacillus johnsonii NCC 533 in host-associated environments may contribute to the overall stability of microbial communities, supporting digestion and possibly offering protective benefits against pathogenic organisms. The understanding of its traits can aid in exploring its applications in probiotic formulations and its role in the microbiome.
