| Description | Lactobacillus salivarius DSM 20555 = ATCC 11741 is a Gram-positive, rod-shaped bacterium that thrives optimally at mesophilic temperatures, typically between 30°C and 37°C. As a heterotroph, this microbe derives its energy from organic compounds, primarily sugars found in its environments, such as the human gastrointestinal tract, oral cavity, and female genitourinary tract. Lactobacillus salivarius is classified as a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, although its fermentation processes are more pronounced under anaerobic conditions. This species belongs to the genus Lactobacillus, which is well-known for its role in the production of lactic acid through carbohydrate fermentation. Such metabolic activity not only aids in the digestion of carbohydrates but also contributes to the maintenance of a balanced gut microbiota. L. salivarius is often found in various body sites, including the mouth, intestines, and vagina, where it plays a crucial role in inhibiting the growth of pathogenic bacteria and maintaining mucosal health.Lactobacillus salivarius is also recognized for its probiotic properties, contributing to the prevention of gastrointestinal disturbances such as diarrhea and irritable bowel syndrome. Additionally, it may enhance immune system functions and has been studied for its potential in reducing the risk of respiratory infections. Its presence in fermented foods and dietary supplements underlines its significance in promoting gut health and overall well-being, showcasing its beneficial impact on human microbiomes. |
