Question

Match List I with List II:

List I
A. Clostridium butylicum
B. Saccharomyces cerevisiae
C. Trichoderma polysporum
D. Streptococcus sp.

List II
I. Ethanol
II. Streptokinase
III. Butyric acid
IV. Cyclosporin-A

Choose the correct answer from the options given below:
(1) A-III, B-I, C-II, D-IV
(2) A-II, B-IV, C-III, D-I
(3) A-III, B-I, C-IV, D-II
(4) A-IV, B-I, C-III, D-II

Accepted Answer

Correct Answer: C — A-III, B-I, C-IV, D-IIStep-by-step Solution:Microbes are used in industrial production of various useful products:Clostridium butylicum (also known as Clostridium butyricum) is used for the production of butyric acid by fermentation. Hence, A matches with III (Butyric acid).Saccharomyces cerevisiae (baker's yeast) is used in the production of ethanol (alcoholic beverages, biofuel). Hence, B matches with I (Ethanol).Trichoderma polysporum is a fungus that produces cyclosporin-A, an immunosuppressant drug used in organ transplantation. Hence, C matches with IV (Cyclosporin-A).Streptococcus sp. (particularly Streptococcus pyogenes) produces streptokinase, a fibrinolytic enzyme used to dissolve blood clots. Hence, D matches with II (Streptokinase).Thus, A-III, B-I, C-IV, D-II corresponds to option C.Key Concepts: Industrial microbiology, microbial products: butyric acid, ethanol, cyclosporin-A, streptokinase. Application in biotechnology.
