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

Solution & Explanation

Related Formula
Swiss Cheese Holes = Production of large volume of CO₂ by Propionibacterium sharmanii
Core Logic

The large characteristic holes in 'Swiss Cheese' are caused by the production of a large amount of carbon dioxide (CO₂) gas during fermentation by the bacterium Propionibacterium sharmanii.

Step 1: Conclusion

Option (4) is the correct statement.

Pattern Recognition

Sees: "Swiss Cheese large holes". Shortcut: Propionibacterium sharmanii producing large amounts of CO₂.
