Detailed explanation-1: -Louis Pasteur discovered fermentation in 1857. In 1857 he demonstrated that lactic acid corrosion is caused by a microorganisms. In 1860 he recognized that job of microorganism prompted pasteurization.

Detailed explanation-2: -Louis Pasteur (1822–1895) is revered by his successors in the life sciences as well as by the general public. In fact, his name provided the basis for a household word-pasteurized.

Detailed explanation-3: -Pasteur was able to prove that living cells, the yeast, were responsible for forming alcohol from sugar, and that contaminating microorganisms found in ordinary air could turn the fermentations sour.

Detailed explanation-4: -Pasteur then cultivated the microorganisms in a culture with his laboratory. He was then able to accelerate the lactic acid fermentation process in fresh milk by administering the cultivated sample to it. This was an important step in proving his hypothesis that lactic acid fermentation was catalyzed by microorganisms.
