Microbes in Action

Microorganisms are very small living organisms that can only be seen through a microscope.

An example of a beneficial microorganism is Lactobacillus bacteria. It helps in the formation of curd and cheese from milk by breaking down the lactose in milk into lactic acid, which causes the proteins in milk to curdle.

Yeast is a microscopic, unicellular fungus that performs fermentation. It converts sugars into ethanol and carbon dioxide. This property of yeast is used in making bread and alcoholic beverages like wine and beer.
