Answer 1

The fermentation process will be slower in colder conditions.

Explanation:

• The process by which the milk is converted into curd is called fermentation.
• During fermentation, a chemical reaction occurs between the lactic acid bacteria and the milk's casein protein.
• Curd is made out of lactic acid. In the fridge, the temperature is low, and bacterial activity is slowed down, creating difficulty in curd formation.
• Lactobacillus is a Gram-positive, aerotolerant, or microaerophilic, rod-shaped, non-spore-forming bacteria.
• Lactobacillus helps keep away the harmful bacteria and infections from the body and curd is loaded with vitamin C.
