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

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).
