Describe the kind of food that would have lactic acid bacteria. Mention their useful applications.

Lactic Acid Bacteria(LAB) of the Lactobacillus species is most commonly found in food items such as curd and yoghurt. During the formation of curd, a small amount of curd is added to milk which acts as an initiator. Microbes present in the starter rapidly multiply at suitable temperatures, thereby causing the conversion of milk into curd. The LAB releases acids during the growth curdle and digest the milk protein partially which thereby facilitates the digestibility of the milk protein. Few of its applications are:

Enhances the nutritional quality of milk by increasing vitamin B-12 content

Regulates disease-checking microbes in the stomach
