What is the reason behind production of large holes in 'Swiss Cheese'?

Solution & Explanation

Core Logic

The large holes in Swiss cheese are due to the production of a large amount of CO₂ by the bacterium Propionibacterium sharmanii.

  • Clostridium butylicum is commercially utilised for butyric acid production.
  • Curd is formed by Lactobacillus.
Pattern Recognition

Swiss cheese = Propionibacterium sharmanii = Large CO₂ production.

Q151 neet_2026_03_may_morning Bioactive Molecules
Match List I with List II:
List I (Bioactive molecules)List II (Importance)
A. StreptokinaseI. Immunosuppressive agent
B. StatinsII. Removal of clots from the blood vessels
C. LipasesIII. Blood cholesterol-lowering agent
D. Cyclosporin AIV. Detergent formulations
Choose the correct answer from the options given below:
  • A. A-II, B-III, C-IV, D-I
  • B. A-IV, B-III, C-II, D-I
  • C. A-II, B-III, C-I, D-IV
  • D. A-III, B-II, C-IV, D-I

Solution

Core Logic

Streptokinase is used as a 'clot buster' for removing clots from the blood vessels. Statins act as a blood cholesterol-lowering agent, produced by Monascus purpureus. Lipases are used in detergent formulations. Cyclosporin A is used as an immunosuppressive agent in organ transplant patients and is produced by Trichoderma polysporum.

Step 1: Final Conclusion

Matching the items gives: A-II, B-III, C-IV, D-I.

Pattern Recognition

Link specific microbes/enzymes with their direct commercial or medical applications (e.g., Streptokinase = clots, Statins = cholesterol).
