Read the passage and answer the following questions :

Yeasts, such as Saccharomyces cerevisiae, have been used for centuries to produce alcoholic beverages like wine, beer, whisky, brandy, and rum. These beverages are made through the fermentation of malted cereals and fruit juices by yeast, specifically brewer's yeast. During fermentation, yeast undergoes metabolic reactions that result in the production of ethanol, the primary alcohol in alcoholic beverages. Different types of alcoholic drinks are obtained based on the raw materials used and the processing methods employed. Wine and beer are produced without distillation, while whisky, brandy, and rum are produced by distilling the fermented mixture. On the other hand, antibiotics, which are chemical substances produced by certain microbes, are considered one of the significant discoveries of the twentieth century. They have greatly contributed to the well-being of human society. Antibiotics are capable of killing or inhibiting the growth of disease-causing microbes, thereby having a positive impact on human health.

Which among the following microbe is used for the production of beverages ?

Yeast

The correct answer is Option (3)-Yeast

Microbes especially yeasts have been used from time immemorial for the production of beverages like wine, beer, whisky, brandy or rum. For this purpose the same yeast Saccharomyces cerevisiae used for bread-making and commonly called brewer’s yeast, is used for fermenting malted cereals and fruit juices, to produce ethanol.Depending on the type of the raw material used for fermentation and the type of processing (with or without distillation) different types of alcoholic drinks are obtained. Wine and beer are produced without distillation whereas whisky, brandy and rum are produced by distillation of the fermented broth.
