Microbes In Food
Easybiology
Curd formation primarily involves which bacterium?
Select the correct option:
Solution
Incorrect! Answer:
Lactobacillus
- Process: Milk contains a natural sugar called lactose.
- 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.
- Curdling: The lactic acid coagulates and partially digests the milk protein (casein), turning the liquid milk into curd.
- Nutritional Benefit: Curd is more nutritious than milk because it contains higher amounts of Vitamin B12 and helps in checking disease-causing microbes in the stomach.
