Even in industry, microbes are used to synthesise a number of products valuable to human beings. Beverages and antibiotics are some examples.
Production on an industrial scale, requires growing microbes in very large vessels called fermentors.

# 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. Do you recollect the metabolic reactions, which result in the production of
ethanol by yeast? 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.
