Explanation:
Detailed explanation-1: -Lactobacillus converts milk to curd by producing lactic acid and reducing the pH of the milk. These bacteria convert the lactose into lactic acid, which imparts the sour taste to curd.
Detailed explanation-2: -Lactobacillus is a genus of bacteria which can convert sugars into lactic acid by means of fermentation. Milk contains a sugar called lactose, a disaccharide(compound sugar) made by the glycosidic bonding between glucose and galactose (monosaccharides). Lactobacillus bacteria are helpful in a formation of curd.
Detailed explanation-3: -Fermentation of milk sugar called lactose by Lactobacillus produces lactic acid. This bacteria denatures milk proteins (casein) so that they clump together to form curd.
