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.
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.
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.
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.
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.
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.
BACTERIA
Lactobacillus acidophilus, a bacteria.
it is made of milk First of all milk is pasteurized to get rid of any harmful bacteria. Then the bacteria Lactobacillus is added. The lactobacillus is cultured at 46 degrees Celsius. This releases lactic acid into the milk which turns it into yogurt.
No. Bacteria help turn milk into yogurt; usually a bacteria named acidophilus.
Milk + Bacteria = Yogurt

The conversion of milk to yogurt is a chemical change. The bacteria in yogurt culture ferment the lactose in the milk into lactic acid, which changes the chemical composition and properties of the milk, resulting in the formation of yogurt.

Milk & Bacteria
Lactic acid is the main type of acid found in milk. It is produced by bacteria during the fermentation process that turns milk into products like yogurt and cheese.
It is made in a factory, and it is made by dairy products like milk. First of all milk is pasteurised to get rid of any harmful bacteria in the milk. Then the bacteria Lactobacillus is added. The lactobacillus is cultured at 46 degrees celcius. This releases lactic acid into the milk which turns it into yoghurt.
