Lactobacillus bulgaricus and Streptococcus thermophilus are the most common bacteria used to ferment milk into yogurt. These bacteria consume the lactose in milk and produce lactic acid, which causes the milk to thicken and develop the characteristic tangy flavor of yogurt.

Which organisms help make yogurt?

Yogurt is typically made by adding live cultures of Lactobacillus bulgaricus and Streptococcus thermophilus bacteria to milk. These bacteria ferment the sugars in the milk, producing lactic acid which gives yogurt its tangy flavor and thick texture.


Why do you need to bring milk to 85 degrees and then cool to 48 degrees when making yogurt?

Heating milk to 85 degrees helps to kill any harmful bacteria present in the milk. Cooling the milk to 48 degrees promotes the growth of beneficial bacteria (culture) needed for yogurt fermentation. This temperature range creates an ideal environment for the culture to thrive and convert the milk into yogurt.


Why would yogurt makers put live bacteria in the yogurt you eat?

The bacteria in yogurt is necessary for the creation of the yogurt - those bacteria are actually what is responsible for transforming the milk into yogurt. They are left alive for you to eat because science is finding certain bacteria are very beneficial for your digestive system and can thus have many beneficial affects on health in general. You can read more about this if you look up "probiotics". Because of this, it is even possible to take these bacteria in pill form to get the benefits without eating the yogurt.


Does freezing kill yogurt cultures?

Yes, freezing can kill some yogurt cultures, which are beneficial bacteria that help ferment the milk into yogurt. When yogurt is frozen, the ice crystals that form can damage the cell walls of the bacteria, potentially reducing their effectiveness.


Is yogurt the food living or non living?

Yogurt is considered a non-living food product. It is made from milk that undergoes fermentation by bacteria cultures, which break down the lactose in the milk to produce lactic acid, giving yogurt its tangy flavor and creamy texture.
