Solution

Correct Answer:

Lactobacillus

  1. Process: Milk contains a natural sugar called lactose.
  2. Lactic Acid Bacteria (LAB): When Lactobacillus (a type of LAB) is added to milk at a suitable temperature, it multiplies and converts lactose into lactic acid.
  3. Curdling: The lactic acid coagulates and partially digests the milk protein (casein), turning the liquid milk into curd.
  4. Nutritional Benefit: Curd is more nutritious than milk because it contains higher amounts of Vitamin and helps in checking disease-causing microbes in the stomach.
