Question

Match LIST-I with LIST-II

LIST-I (Commercial Production)		LIST-II (Microorganism)
A. Citric acid	I. Corynebacterium glutamicum
B. Ethanol	II. Aspergillus niger
C. Amino acids and nucleotides	III. Claviceps purpurea
D. Alkaloids	IV. Saccharomyces cerevisiae

Choose the correct answer from the options given below:

• A. A - II, B - III, C - IV, D - I
• B. A-I, B-III, C - II, D - IV
• C. A - II, B - IV, C - I, D - III
• D. A-III, B - IV, C - I, D - II

Hint:

Associate key products with their microbes: Ethanol $\rightarrow$ Yeast (Saccharomyces), Citric Acid $\rightarrow$ Aspergillus niger, Amino Acids (especially Glutamate) $\rightarrow$ Corynebacterium. These are classic examples in industrial microbiology.

Answer 1

The Correct Option is C

Step 1: Concept Overview:
This question assesses understanding of industrial microbiology, focusing on the microorganisms employed in the large-scale commercial production of specific chemicals.
Step 2: Detailed Solution:
Match each product in LIST-I with its corresponding microorganism from LIST-II:


A. Citric acid: Aspergillus niger is the primary fungus used industrially for citric acid production, matching II.

B. Ethanol: Saccharomyces cerevisiae yeast is well-known for ethanol fermentation in beverage and biofuel production, matching IV.

C. Amino acids and nucleotides: Corynebacterium glutamicum bacterium is widely used in the industrial production of amino acids, especially L-glutamate and L-lysine, matching I.

D. Alkaloids: Claviceps purpurea fungus produces ergot alkaloids, utilized in various pharmaceutical applications, matching III.

Step 3: Conclusion:
The correct matches are A-II, B-IV, C-I, D-III, corresponding to option (C).
