Streptococcus salivarius subsp.thermophilus

Detailed information

Postbiotics are derived from the fermentation of qualified raw materials by lactic acid bacteria or probiotics, followed by inactivation of the resulting product. This process may include solid-liquid separation and optional drying treatments.

Streptococcus thermophilus

Streptococcus thermophilus is recognized as a "Generally Recognized As Safe (GRAS)" ingredient, making it a staple in the manufacturing of various significant fermented dairy products, including yogurt and an array of cheeses such as Swiss and Limburger. Beyond its safety status, Streptococcus thermophilus exhibits a multitude of functional properties, which include the production of extracellular polysaccharides, bacteriocins, and essential vitamins that contribute to its overall efficacy in food production.

Furthermore, Streptococcus thermophilus also imparts several beneficial effects on health and wellness:

1. **Enhancement of the Intestinal Microenvironment**: This bacterium plays a role in reducing intestinal pH levels, thereby fostering a favorable environment that promotes intestinal peristalsis. This action not only helps deter the colonization of pathogenic bacteria but also initiates the secretion of bacteriocins, which specifically target and inhibit the growth of harmful bacterial strains.

2. **Regulation of Blood Pressure**: Streptococcus thermophilus has been noted for its ability to inhibit the activity of cholesterol synthetase, which contributes to a reduction in serum cholesterol levels. The fermentation products generated by this bacterium also possess properties that assist in modulating blood pressure, presenting a possible avenue for dietary hypertension management.

3. **Anti-Cancer Properties**: The metabolic activities of Streptococcus thermophilus lead to the production of beneficial compounds such as polysaccharides, bacteriocins, and lactic acid, all of which have demonstrated anti-tumor effects. This highlights its potential role in cancer prevention strategies.

4. **Stimulation of the Immune System**: This microorganism is capable of activating the body's immune response, helping to suppress cellular mutations that could lead to tumor formation. This immunomodulatory effect is instrumental in resistance to various forms of cancer.

5. **Aging Delay Mechanisms**: The generation of superoxide dismutase (SOD) by Streptococcus thermophilus serves a vital function in cellular metabolism. SOD plays a crucial role in mitigating oxidative stress by neutralizing superoxide anion free radicals, thereby contributing to the delay of aging processes in the body.

6. **Facilitation of Lactic Acid Production**: The breakdown of lactose necessitates the presence of the specific enzyme β-galactosidase. In individuals with lactose intolerance, the deficiency of this enzyme leads to digestive discomfort. Streptococcus thermophilus is proficient in producing β-galactosidase, which facilitates the digestion of lactose, thus providing support for those who experience lactose intolerance.

Overall, the multifaceted roles of Streptococcus thermophilus in both food production and health enhancement underscore its significance in the realms of microbiology and nutrition.
