Match List I with List II List I (Microbes) List II (Industrial products) (A). Aspergillus niger (I). Enzyme-Invertase (B). Pseudomonas denitrificans (II). Citric acid (C). Saccharomyces cerevisiae (III). Chloromycetin (D). Streptomyces venezuelae (IV). Vitamin- B ₁₂ Choose the correct answer from the options given below:
Options
- A(A) - (I), (B) - (II), (C) - (III), (D) - (IV)
- B(A) - (II), (B) - (IV), (C) - (I), (D) - (III)
- C(A) - (I), (B) - (II), (C) - (IV), (D) - (III)
- D(A) - (III), (B) - (IV), (C) - (I), (D) - (II)
Correct answer
B. (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
Step-by-step solution
Aspergillus niger is a fungus used for the commercial and industrial production of Citric acid. Thus, (A) matches with (II). Pseudomonas denitrificans is a bacterium used for the commercial production of Vitamin- B ₁₂ . Thus, (B) matches with (IV). Saccharomyces cerevisiae (commonly known as baker's yeast) is used for the production of the enzyme Invertase. Thus, (C) matches with (I). Streptomyces venezuelae is a species of soil-dwelling Gram-positive bacterium that produces the antibiotic Chloromycetin (also known
