The good bacteria used in the preparation of yogurt are called Lactobacillus bulgaricus and Streptococcus thermophilus. These are friendly bacteria that help turn milk into yogurt.

Preparation of Yogurt

First, the milk is heated to kill any harmful bacteria. Then, it’s cooled down, and the good bacteria are added. These bacteria eat the sugars in the milk and produce lactic acid. The lactic acid makes the milk thick and gives yogurt its tangy taste.

Lactobacillus bulgaricus and Streptococcus thermophilus work together to make yogurt healthy. They help our digestive system by increasing the number of good bacteria in our gut. This can help us digest food better and keep our stomachs healthy.

These bacteria not only transform the milk but also provide health benefits. They help maintain a healthy balance of gut bacteria, aid digestion, and boost the immune system. Additionally, consuming yogurt with live cultures of these bacteria can improve lactose digestion for people who are lactose intolerant.
