Question

Under the guidance of your mother or an elder at home make arrangement for the formation of curd. Write your experience in the form of a paragraph. Also write the name of bacteria involved in formation of curd.​

Answer 1

Answer: The experience of making curd was valuable. I, along with my mother(or any other elder) conducted this experiment. First of all, we heated some milk until it was luke warm and then added two spoonfuls of curd into the vessel containing milk. The vessel was then closed with a lid. This setup was then kept aside for 6-7 hours and then when we removed the lid, we saw that the milk was completely converted into curd.

My mother told me that this phenomenon took place due to presence of the bacteria known as lactobacillus present in the curd. this bacteria spreads in the luke warm milk when left undisturbed for some time and converts the milk into curd.
