Best answer
Milk contains sugar called lactose which is broken down with help of Lactobacilli. Lactobacilli converts lactose into Lactic Acid. This process is called fermentation. As a result, the pH of milk decreases causing coagulation of milk proteins. Thus, milk proteins are separated from other constituents of milk and milk changes to yoghurt.
