- coagulation and partial digestion of milk proteins
- coagulation of milk proteins and complete digestion of milk fats
- coagulation of milk fats and complete digestion of milk protein
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Lactobacillus is a genus of Gram-positve, facultative, anaerobic or microaerophilic bacteria. Lactic Acid Bacteria (LAB) grow in milk and convert it to curd.
During growth, LAB produce acids that coagulate and partially digest the milk proteins.

Microbes in Human Welfare
There are several valuable microorganisms that are beneficial to humans in various manners such as:
In Household Products
- Fermentation of milk to produce yogurt.
- Milk cuddling to compose curd, cheese, and paneer.
In Industrial Products
- Production of beverages such as wine, beer, whiskey, brandy, or rum.
- Production of antibiotics such as Penicillin and other chemical substances to kill or retard the expansion of disease-causing microbes.
Fermented Beverages
- A fermentor is used to produce microbes on a large scale for industrial purposes.
- The brewer’s yeast (Saccharomyces cerevisiae) is used to make ethanol. At this time, the yeast ferments malted cereals and fruit juices.
Antibiotics
- The term antibiotic means “against life”. These materials can kill or destroy the growth of other microbes.
