Question

Match List I with List II

Choose the correct answer from the options given below:

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

Hint:

A. flavus $\to$ Aflatoxin; P. expansum $\to$ Patulin; A. versicolor $\to$ Sterigmatocystin; C. purpurea $\to$ Ergot alkaloids.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Mycotoxins are secondary fungal toxic metabolites produced by specific toxigenic mould species in food and agricultural commodities.

Step 2: Detailed Explanation:
Matching each toxigenic fungus in List I with its corresponding mycotoxin in List II:
1. Aspergillus flavus (A) $\to$ Aflatoxins (III): Produces aflatoxins $B_1, B_2, G_1, G_2$ in peanuts, maize, and tree nuts.
2. Penicillium expansum (B) $\to$ Patulin (IV): Causes blue mould rot in apples and produces the lactone mycotoxin patulin in apple juice.
3. Aspergillus versicolor (C) $\to$ Sterigmatocystin (II): Produces sterigmatocystin, a precursor in the aflatoxin biosynthetic pathway.
4. Claviceps purpurea (D) $\to$ Ergotin Ergot alkaloids (I): Infects rye and cereals causing ergotism via toxic ergot alkaloids (ergotamine, ergometrine).

Step 3: Final Answer:
Matching summary: A $\to$ III, B $\to$ IV, C $\to$ II, D $\to$ I.
