Lactobacillus delbrueckii subsp. bulgaricus DSM 20081 is a thermophilic lactic acid bacterium best known as one of the two starter cultures used in traditional yogurt fermentation. Research on this specific strain is primarily in vitro and focuses on its enzymatic properties — notably its beta-galactosidase enzyme, which breaks down lactose and can synthesize prebiotic galacto-oligosaccharides. Strain-specific evidence for probiotic effects in humans is limited; this organism is generally regarded as a fermentation workhorse rather than a well-characterized probiotic, and most of its health associations arise from species-level yogurt research rather than controlled trials with this particular strain designation.
