In which food would you find lactic acid bacteria? Mention some of their useful applications.
As I've mentioned in the tip section that is usually grow in the milk so we can found these bacteria in dairy products/beverages. Some lactic acid bacteria such as Streptococcus, Leuconostoc, Lactobacillus or Lactococcus specifically produce lactic acid during the fermentation process. Lactic acid leads to coagulation of milk protein casein from which curd, cheese, buttermilk, yogurt, butter etc are produced. Curd - Lactobacillus lactis is used to produce curd from milk. The temperature is retained between 32-40°C. Cheese - To produce cheese Brevibacterium is used. Initial product is condensed milk. Buttermilk - It is made from fat-free milk (skim milk) by adding a starter culture of Lactobacillus lactis subspecies cremoris and Leuconostoc citrovorum. Yogurt - Yogurt production utilizes starter cultures of Streptococcus thermophilus and Lactobacillus bulgaricus.
