Alcohol fermentation by microbes to obtain different types of alcoholic beverages is mainly based on the: Correct Answer All of these

Concept:

  • Alcohol Fermentation: The biological process, in which sugar molecules are converted into ethyl alcohol and carbon dioxide with the help of some microbes like yeast and bacteria is called alcohol fermentation.
  • It is an anaerobic process i.e. it occurs in the absence of oxygen.
  • Different types of alcoholic beverages can be obtained using alcoholic fermentation.
  • These are mainly based on:
  1. Distillation process
  2. Type of nutrient medium used
  3. Type of brewer's yeast used

Explanation:

  • Different alcoholic beverages are obtained on the basis of:
  1. Distillation process: Wine & Beer are obtained without distillation whereas whisky, brandy, and rum are produced by distillation of the fermented broth.
  2. Type of nutrient medium used: Beer is obtained by fermentation of grain-mesh whereas, Wine is obtained by fermentation of fruit juices.
  3. Type of Breyer's yeast used: Fermentation of mesh-grains to obtain Beer is brought about by Saccharomyces cerevisiae and S. carisbergensis.
  • Fermentation of fruit juices to obtain wine is brought about by Saccharomyces ellipsoidens.
  • Thus, option 2 is correct
