| LIST-I | LIST-II |
|---|---|
| Microbes | Products |
| (A) Streptococcus | (I) Immunosuppressive agent |
| (B) Trichoderma polysporum | (II) Ethanol |
| (C) Saccharomyces cerevisiae | (III) Biogas |
| (D) Methanobacterium | (IV) Clot buster |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
(A) Streptococcus — this matches (IV) Clot buster. This bacterium makes the enzyme streptokinase. After changes by genetic engineering, it is used to dissolve blood clots in the blood vessels of patients who have had a heart attack.
(B) Trichoderma polysporum — this matches (I) Immunosuppressive agent. This fungus makes cyclosporin A. It suppresses the immune system, so it is given to organ-transplant patients to stop the body from rejecting the new organ.
(C) Saccharomyces cerevisiae — this matches (II) Ethanol. This yeast ferments sugars, so it is used for the commercial production of ethanol and for making wine and beer.
(D) Methanobacterium — this matches (III) Biogas. It is a methanogen. It grows without oxygen on cellulose-rich material such as cattle dung and gives out a lot of methane, the main gas of biogas.
