Plz asap bacteria cultures that have been allowed to undergo fermentation have been used commercially for centuries in the production of? a. bread b. beer c. wine d. yogurt

The process of fermentation of milk by bacteria is employed in the production of Yogurt.

Explanation:

Fermentation refers to a metabolic process in which organism such as yeast or bacteria under desirable condition converts milk into certain acids. In case of Bread, Beer and wine, the fermentation process is done with the help of yeast Saccharomyces cerevisiae. On the other hand, the bacteria fermentation of milk leads to yogurt.

It employs bacterial species such as Streptococcus thermophilus and Lactobacillus bulgaricus. These bacteria ferment the milk by consuming the sugar content of the milk and releases lactic acid. By this way the milk is fermented into Yogurt.
