Like lactobacillus. These bacteria secrete lactic acid which changes the Ph of milk and proteins are very sensitive to change in Ph. So this changed Ph to destruction of secondary and tertiary structures of protein (called denaturation). Which leads to precipitation of milk proteins and lead to curd formation.
Milk has many globular proteins. Milk is converted into curd or yoghurt by action of bacteria.

Answer:
Milk contain Protein called casein. this protein give milk its characteristic white colour. It is of high nutritional value because it contain all essential amino acid required by men's body. The curd form because of chemical reaction between lactic acid bacteria and casein. When curd is added to milk the lactic acid bacteria present in it cause coagulation of casein and thus convert it into curd.
