MyCompetitiveExams Dynamic 180-question full-length simulator mixed dynamically from all 6 years for 2027 & 2026 aspirants.
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:
Clostridium butylicum -> Butyric acid (III). Streptococcus -> Streptokinase (II). Direct two-point confirmation locks Option (1)!
Clostridium butylicum is a bacterium that ferments substrates to produce butyric acid (A -> III). Saccharomyces cerevisiae (Brewer’s yeast) ferments malted cereals and fruit juices to produce ethanol (B -> I).
Trichoderma polysporum (fungus) produces Cyclosporin-A, an immunosuppressive agent used in organ-transplant patients (C -> IV). Streptococcus produces streptokinase, modified by genetic engineering and used as a "clot buster" to remove clots from blood vessels of patients suffering from myocardial infarction (D -> II).
The unique valid combination is A-III, B-I, C-IV, D-II, corresponding to Option (1).
Diagnose every choice: Know exactly why the right option works and why distractors fail.
Accurately pairs all four microbes with their corresponding commercial or medicinal products.
Mismatches Clostridium with Streptokinase and Saccharomyces with Cyclosporin-A.
Mismatches Clostridium with Cyclosporin-A and Trichoderma with Butyric acid.
Mismatches Saccharomyces with Cyclosporin-A and Streptococcus with Ethanol.
Confusing Trichoderma polysporum (Cyclosporin-A) with Monascus purpureus (Statins).
"Examples of acid producers are Aspergillus niger of citric acid, Acetobacter aceti of acetic acid; Clostridium butylicum of butyric acid. Trichoderma polysporum produces cyclosporin A and Streptococcus produces streptokinase."
