Updated On: May 30, 2026
- Saccharomyces cerevisiae
- Lactobacillus
- Rhizobium
- Aspergillus
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Curd formation is a biochemical process where milk proteins are coagulated by the action of specific bacteria that convert sugars into acid.
Step 2: Key Formula or Approach:
Lactic Acid Bacteria (LAB) are the primary agents in dairy fermentation.
Step 3: Detailed Explanation:
Lactobacillus bacteria convert the lactose sugar found in milk into lactic acid. This acid lowers the pH of the milk, causing the milk protein (casein) to denature and coagulate, turning the liquid milk into a thick solid (curd).
Step 4: Final Answer:
Lactobacillus is the organism used in the production of curd.
