Question

Curd formation primarily involves which bacterium?

RankGuru · Accepted Answer

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 $B_{12}$** and helps in checking disease-causing microbes in the stomach.
