It is used to ferment the milk
The growth of the bacteria in the milk is what makes the milk become yogurt. If they are not alive, you won't be able to make yogurt. If the milk is too hot when the culture is added, the bacteria will die and the process will fail. If the milk is kept too cold, the bacteria won't grow and the process will fail.
Yogurt has a lot of good bacteria in it, which would replace the good bacteria you may be lacking. It balances your body's pH and keeps the intestinal tract on track. It will also help for a woman if she has a yeast infection or her pH is off. You can actually use the yogurt as a douche for a few days to replace good bacteria in the vagina and help treat the yeast infection. It can replace and help more than medications can. Just make sure the yogurt has the live active cultures and is plain (not flavored with fruits like strawberry, etc.)

Microbes might be either useful or harmful. Those that cause disease are of course, harmful, but there are millions of microbes in your body that aid in functions such as digestion. There are also microbes that occur in food products. Yeast is a good example. Also yogurt contains microbes as part of the product.
I am not an expert, but my experience has been that freezing does not destroy the cultures. I make my own yogurt and to have starter, I buy a quart of plain yogurt and freeze it in ice cube trays. The frozen starter still makes a good yogurt, so the cultures clearly survive the freezing. Previously frozen yogurt is not very palatable out of the freezer, in my experience.I think cold in general doesn't bother microbes in the short term (six months to a year, something like that). Cold puts microbes in suspended animation, but heat kills them.
milk is boiled to kill of any unwanted microbes. bacteria are then added which release enzymes that make the milk go thick and slightly sour. flavouring can be added to yogurt to change the taste.
1) Microbes helps in bio degradation and decomposition. 2) Microbes helps in fermentation process to take place. 3) Microbes helps in bio transformation as well. That is one biological compound is transformed to another useful biological compound with the help of microbes.
Microbes are single celled living things too small to see. All higher life forms depend to some extent on microbes. Microbes are what turn milk into yogurt, and may be found there. They cause bread to rise. They may be found in bread dough. They are used to make sauerkraut, kimchee and certain other kinds of pickles, and can be found there. Microbes are at the base of the food chain. They are eaten by tiny animals that are, in turn, eaten by larger animals. Microbes are important in composting and putting nitrogen into the soil. There are many kinds of beneficial microbes in the soil. Cows and horses and many other kinds of plant eating animals have microbes in their stomachs and intestines. These microbes break down cellulose, which is what the cell walls of the plants the eat are made of. Without these microbes, the cows and horses would die. In fact, we could guess that all animals with intestines have microbes in them. We could go on. And on. and on.
microbes r very helpful in food production today .it helps in fermentation and produces large amount of yogurt,cheese,alcohols,bread,bun,,brewery industry based upon it.
The heating step helps to inactivate enzymes responsible for spoilage, removes oxygen (to stop growth of microbes that need air to live), increases viscosity and inactivates antibodies.
Alexander flaming discovered microbes
microbes can live anywhere!
sometimes Bactria can kill microbes
Fermentation process microbes.
