Which bacteria helps milk to change into curd?
Rennin deactivate the casein micelles in milk, causing a distinct separation of curd protein (solid) and whey protein (liquid).
What is the process of converting milk into curd?
To convert milk into curd, heat the milk to a lukewarm temperature, add a small amount of curd culture or curd from a previous batch, and let it sit undisturbed in a warm place for 6-8 hours to allow the milk to ferment and curdle. The bacteria in the culture will convert the sugars in the milk into lactic acid, thickening the milk and turning it into curd.
Why is milk turning sour during summers in chemical change?
During summers, milk can turn sour due to a chemical change called souring. This is caused by the growth of bacteria in the milk, which metabolize the lactose (milk sugar) into lactic acid. The lactic acid decreases the pH of the milk, giving it a sour taste and causing the proteins to denature.

If pH of milk is 6 then what will be the pH of curd?
no change
How lactobacillus make milk to curd?
Lactobacillus is a type of beneficial bacteria that plays a key role in the fermentation process that turns milk into curd. When milk is inoculated with Lactobacillus, it ferments the lactose (milk sugar) and converts it into lactic acid. This acid causes the proteins in milk, particularly casein, to coagulate and form the thick, creamy texture of curd. The fermentation process also enhances the nutritional value of the milk by introducing probiotics, which promote gut health.
