Yoghurts are made by fermenting (
curdling) milk with two bacteria, streptococcus thermophilus and lactobacillus bulgaricus, which produce an acid that preserves the yoghurt and kills off harmful bacteria such as salmonella.
Acids are added to cheese at several points in the process: during the initial step of
curdling the milk, when a cheesemaker can add vinegar or lemon juice, and then later, as bacteria in the cheese break down milk sugars.
Starter cultures speed and control the process of
curdling milk during cheese making in part by converting lactose to lactic acid.
One of the modern technologies employed in the
curdling of milk is the use of commercial preparations of lactic acid bacterial cultures and milk coagulants, which are usually imported.
