Match List-I with List-II:List-IList-IIA. StreptococcusI. Citric acid…

The correct answer is Option (4) → A-II, B-I, C-IV, D-III

Each microbe in List-I gives us one product or belongs to one group named in List-II.

(A) Streptococcus — this matches (II) Streptokinase. Streptokinase is made by the bacterium Streptococcus and, after modification by genetic engineering, is used as a ‘clot buster’ to remove clots from blood vessels of heart patients.

(B) Aspergillus niger — this matches (I) Citric acid. This fungus is used for the commercial production of citric acid, one of the organic acids made by microbes.

(C) Baculoviruses — this matches (IV) Nucleopolyhedrovirus. Baculoviruses attack insects and other arthropods, and most of those used as biocontrol agents belong to the genus Nucleopolyhedrovirus.

(D) Penicillium notatum — this matches (III) Penicillin. Fleming named the antibiotic Penicillin after this mould, which produced it.

So the matching is A-II, B-I, C-IV, D-III.

NCERT Extract:
Chemicals, Enzymes and other Bioactive Molecules – “… Examples of acid producers are Aspergillus niger (a fungus) of citric acid, Acetobacter aceti (a bacterium) of acetic acid; Clostridium butylicum (a bacterium) of butyric acid and Lactobacillus (a bacterium) of lactic acid. … Streptokinase produced by the bacterium Streptococcus and modified by genetic engineering is used as a ‘clot buster’ for removing clots from the blood vessels of patients who have undergone myocardial infarction leading to heart attack.”
Antibiotics – “… He found out that it was due to a chemical produced by the mould and he named it Penicillin after the mould Penicillium notatum.”
Microbes as Biocontrol Agents – “… Baculoviruses are pathogens that attack insects and other arthropods. The majority of baculoviruses used as biological control agents are in the genus Nucleopolyhedrovirus.”
