Probiotic Strains: Streptococcus Thermophilus

Streptococcus thermophilus is a type of bacteria commonly found in the human gut and is a key starter culture in yogurt production. It is a facultative anaerobe, meaning it can grow with or without oxygen. It is typically grown in a controlled environment using specific nutrient media.

This bacterium is primarily used as a probiotic to support gut health and as a starter culture in the fermentation of dairy products, especially yogurt. It helps break down lactose, contributing to the texture and flavor of yogurt. It is found in various dairy products like yogurt, kefir, and some cheeses.

Streptococcus thermophilus is generally recognized as safe (GRAS) by the FDA for use in food. It is considered a beneficial microorganism that may aid in digestion and lactose tolerance. International bodies like JECFA have evaluated probiotics, but specific numeric limits are not typically set for live cultures. Research is ongoing into the full range of health benefits and potential effects of probiotic strains.
