Question

Match List-I with List-II:

List-I(Microbes)	List-II (Acid Produced)
(A) Aspergillus	(I) Lactic acid
(B) Acetobacter	(II) Butyric acid
(C) Clostridium	(III) Acetic acid
(D) Lactobacillus	(IV) Citric acid

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

Answer 1

The Correct Option is A

To match the microbes from List-I with the acids they produce from List-II, we need to know the specific metabolic products associated with each microbe's fermentation process: 

• Aspergillus is known for producing citric acid in industrial processes. Thus, Aspergillus corresponds with List-II option (IV) Citric acid.
• Acetobacter is primarily involved in the conversion of ethanol into acetic acid, a key step in vinegar production, so it matches with (III) Acetic acid.
• Clostridium species are known for producing butyric acid among other products in anaerobic conditions, thus it should be paired with (II) Butyric acid.
• Lactobacillus is commonly associated with the production of lactic acid and is used in the fermentation of dairy products, aligning it with (I) Lactic acid.

Based on this analysis, the correct matching of List-I with List-II is: (A)-(IV), (B)-(III), (C)-(II), (D)-(I).

Answer 2

Let's match each microbe with the corresponding acid it produces:

(A) Aspergillus: Aspergillus is a genus of fungi that is involved in the production of citric acid. This is commonly used in food and beverage industries, making (A)-(IV) correct.

(B) Acetobacter: Acetobacter is a genus of bacteria known for producing acetic acid (vinegar) during the fermentation process. Thus, (B)-(III) is correct.

(C) Clostridium: Clostridium species, such as Clostridium butyricum, produce butyric acid. This acid is involved in fermentation processes, making (C)-(II) correct.

(D) Lactobacillus: Lactobacillus is a bacterium that produces lactic acid, particularly in the fermentation of dairy products. So, (D)-(I) is correct.

Thus, the correct matching is:

(A)-(IV): Aspergillus → Citric acid

(B)-(III): Acetobacter → Acetic acid

(C)-(II): Clostridium → Butyric acid

(D)-(I): Lactobacillus → Lactic acid

The correct answer is (1) (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
