Lactobacillus delbrueckii is a lactic acid bacterium widely used in yogurt fermentation and industrial applications. The species comprises several subspecies (delbrueckii, bulgaricus, and lactis). Research has examined mechanisms of lactic acid production, fermentation characteristics, and viability in food matrices, as well as in vitro studies on antioxidative peptide production and physiological properties. Limited clinical research has investigated potential antifungal effects in animal models. The strain is primarily studied in fermentation science and food microbiology contexts.
Where it's been studied Tags come from a conservative keyword scan of each paper's title, abstract, and summary. A tag is research coverage, not measured effect. How we classify this →
Share of this strain's 225 body-system-tagged papers that concern each system. Research coverage, not measured effect.
Symptoms in the research A tag means the paper's text names the symptom or condition — research coverage, not evidence of benefit. How we classify this →
Share of this strain's 85 symptom-tagged papers that mention each symptom or condition. Research coverage, not evidence of benefit.
