(See notes below about incubation tricks.) The low temperature and long ferment time allow the bacteria to consume all the sugar present in the milk and create billions of beneficial bacteria. Just as good bacteria (in the starter culture) consume the sugar in milk, bad bacteria (living inside our digestive system) also like to consume sugar. Different foods require different types of bacteria: common types are Lactobacillus bulgaricus, streptococcus thermophiles, and Leuconostoc. Yogurt Fermentation.
