Lactobacillus salivarius SP2

exemple Lactobacillus salivarius SP2


Lactobacillus salivarius is a microbiota bacterium which, as its name suggests, is present in saliva and therefore in the oral cavity, but also in the intestine. Classified as a Gram-positive bacteria, Lactobacillus salivarius belongs to the phylum Firmicutes and uses lactose as an energy source in order to grow.


Its speed of proliferation allows it to colonise the intestines rapidly and thus compete with other potentially pathogenic bacteria. In addition, Lactobacillus salivarius produces molecules with bactericidal properties.


Studies have shown that the presence of Lactobacillus salivarius helps to reduce the presence of bacteria that attack the periodontium, i.e. all the tissues supporting the teeth (gum, alveolar bone, alveolar ligament). These pathogenic bacteria, such as Streptococcus mutans, are responsible for periodontal disease. The action of Lactobacillus salivarius reduces the colonisation of the mucous membranes of the oral cavity by pathogens and favors the stabilisation of the pH in the oral cavity, thus preventing the development of caries and the appearance of periodontal diseases.

The benefits

The production of bacteriocins (antimicrobial peptides) by Lactobacillus salivarius helps to reduce the proliferation of pathogenic bacteria, particularly in the oral cavity.


The particularities of THERASCIENCE laboratory

In order to protect the strains during their passage through the various parts of the digestive tract, but also to guarantee their protection against oxidation, humidity, as well as any interaction with other components, THERASCIENCE Laboratory carries out an individual microencapsulation of the various strains of microbiota thanks to different patented processes : PROBIO PROTECT®.
