Which of the following statements represent correct applications of microbes in human welfare?
A. Cyclosporin A is used as an immunosuppressant and produced by Trichoderma polysporum.
B. Ethanol production by Saccharomyces cerevisiae for commercial purposes.
C. Streptokinase production by Clostridium butylicum for clot buster in heart attack.
D. Statins production by Aspergillus niger for balancing blood-cholesterol level.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A and B only
(A) Cyclosporin A is used as an immunosuppressant and produced by Trichoderma polysporum. — Correct. This fungus makes cyclosporin A. It holds back the immune system and is used in organ transplants, so that the body does not reject the new organ.
(B) Ethanol production by Saccharomyces cerevisiae for commercial purposes. — Correct. This yeast, called brewer’s yeast, ferments sugar to make ethanol. It is used to produce wine, beer and other drinks.
(C) Streptokinase production by Clostridium butylicum for clot buster in heart attack. — Incorrect. Streptokinase is made by the bacterium Streptococcus. It is used as a clot buster. Clostridium butylicum is used to make butyric acid.
(D) Statins production by Aspergillus niger for balancing blood-cholesterol level. — Incorrect. Statins come from the yeast Monascus purpureus. Aspergillus niger is used to make citric acid.
