Question:
Microorganism used in industrial biotechnology for the production of Vitamin \(B_{12}\) is:
Microorganism used in industrial biotechnology for the production of Vitamin \(B_{12}\) is:
Show Hint
$B_{12}$ Producers: "Pseudo" and "Propion" (Pseudomonas and Propionibacterium).
Updated On: May 25, 2026
- Escherichia coli
- Lactobacillus acidophilus
- Pseudomonas denitrificans
- Saccharomyces cerevisiae
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Industrial production of complex vitamins like $B_{12}$ is performed exclusively through microbial fermentation because chemical synthesis is too complicated.
Step 2: Meaning
Highly efficient bacterial strains are selected for their ability to synthesize large quantities of the vitamin under controlled conditions.
Step 3: Analysis
Pseudomonas denitrificans and Propionibacterium shermanii are the primary organisms used globally for the commercial production of Vitamin $B_{12}$.
Step 4: Conclusion
Among the given options, Pseudomonas denitrificans is the industrial choice. Final Answer: (C)
