what types of bacteria are typically found in yogurt
It may come as a surprise to some that certain kinds of bacteria, such as those found in yogurt, are actually beneficial rather than harmful. Different types of bacteria in yogurt commonly include Lactobacillus bulgaricus, Streptococcus thermophilus, and, in some cases, Lactobacillus acidophilus, Lactobacillus casei, and bifidobacteria. Yogurt has been eaten for so long that no one is really sure how the idea of introducing bacteria to milk in order to produce this rich, tangy food first came about.
