How is milk converted into curd ? Explain the process of curd formation.

Explanation

The LAB bacteria grows in milk and convert it into curd, thereby digesting the milk protein casein. A small amount of curd added to fresh milk as a starter or inoculum contains millions of Lactobacilli, which under suitable temperature `(le 40^(@)C)` multiply and convert milk into curd. Curd is more nutritious than milk as it contains a number of organic acids and vitamins.
