What causes milk to curdle?
This is what happens when milk curdles. When pH levels drop in milk, it turns acidic and milk protein (casein and others) molecules attract one another to form “curdles” or lumps. These lumps then float on the surface of the solution. The lumps are formed faster at warmer temperatures.

Why did my milk curdle in the fridge?
Curdled milk is basically the precipitation of casein protein due to a lowering of the solution pH. Usually this is because some bacteria acidify the milk, thus lowering the pH. If bacteria is the case, usually the ones that produce this lactic acid will do you no harm.
Why does Microwave curdle milk when heated?
The problem you are facing is that your microwave temperature is too high and boils your milk too rapidly. The microwave does not heat food evenly and boils the milk too fast. Milk shouldn’t be boiled too rapidly and doing this causes the casein in it to clump together and that curdles the milk.
