What makes yogurt - well, yogurt? The words live and active cultures refer to the living organisms, Lactobacillus bulgaricus and Streptococcus thermophilus, which convert pasteurized milk to yogurt during fermentation. Note that the milk is pasteurized before culturing to remove any harmful bacteria.
