Question

Match List-I with List-II: 

List-I		List-II
(A)	Glutamic Acid	(II)	Corynebacterium sp.
(B)	α-Amylase	(III)	Aspergillus sp.
(C)	Fumaric Acid	(I)	Rhizopus sp.
(D)	Riboflavin	(IV)	Ashbya sp.

• A. \(A\text{-I},\ B\text{-IV},\ C\text{-III},\ D\text{-II}\)
• B. \(A\text{-II},\ B\text{-III},\ C\text{-I},\ D\text{-IV}\)
• C. \(A\text{-III},\ B\text{-II},\ C\text{-IV},\ D\text{-I}\)
• D. \(A\text{-IV},\ B\text{-I},\ C\text{-II},\ D\text{-III}\)

Hint:

Remember:
• Corynebacterium \(\rightarrow\) Glutamic acid
• Aspergillus \(\rightarrow\) \(\alpha\)-Amylase
• Rhizopus \(\rightarrow\) Fumaric acid
• Ashbya \(\rightarrow\) Riboflavin

Answer 1

The Correct Option is B

Concept: Microorganisms are widely used in industrial microbiology for production of:
• Amino acids
• Enzymes
• Organic acids
• Vitamins Different microbes are associated with production of specific metabolites.

Step 1: Matching Glutamic Acid. Glutamic acid is industrially produced using: \[ \textit{Corynebacterium} \ sp. \] especially: \[ \textit{Corynebacterium glutamicum} \] Thus: \[ A \rightarrow II \]

Step 2: Matching \(\alpha\)-Amylase. \(\alpha\)-Amylase is commonly produced by: \[ \textit{Aspergillus} \ sp. \] such as: \[ \textit{Aspergillus oryzae} \] Thus: \[ B \rightarrow III \]

Step 3: Matching Fumaric Acid. Fumaric acid is produced using: \[ \textit{Rhizopus} \ sp. \] Thus: \[ C \rightarrow I \]

Step 4: Matching Riboflavin. Riboflavin (Vitamin \(B_2\)) is commercially produced by: \[ \textit{Ashbya} \ sp. \] particularly: \[ \textit{Ashbya gossypii} \] Thus: \[ D \rightarrow IV \]

Step 5: Determining the correct combination. Therefore: \[ \boxed{ A\text{-II},\ B\text{-III},\ C\text{-I},\ D\text{-IV} } \] Hence, the correct answer is: \[ \boxed{(B)\ A\text{-II},\ B\text{-III},\ C\text{-I},\ D\text{-IV}} \]
