                                First isolated in 1905, *Lactobacillus bulgaricus* is a key probiotic organism known for its crucial role in fermenting milk into yogurt, a process that converts lactose into lactic acid. This lactic acid not only imparts yogurt's characteristic tangy flavor and thick texture but also provides significant health benefits related to digestion and the immune system.
