Boiling water : -
Boiling water destroyes all the vegetative cells. But this method does not assure complete sterility of contaminated material or the object because the resistant bacterial spores can withstand this condition for many hours.
Pasteurization : -
Milk and some other beverages are subjected to a controlled heat treatment called pasteurization. In which even all vegetative cells are not killed. But only some of them which may be pathogenic are killed. The pasteurized milk in not the sterilized milk.
