Detailed explanation-1: -For example, the large holes in ‘Swiss cheese’ are due to production of a large amount of CO2 by a bacterium named Propionibacterium sharmanii.
Detailed explanation-2: -Swiss cheese contains huge holes because the Propionibacterium shermanii bacteria produce a lot of carbon dioxide. When Propionibacterium shermanii eats lactic acid, it produces carbon dioxide and bubbles. The bubbles do not dissipate; instead, they generate little air pockets that form the holes in the Swiss cheese.
Detailed explanation-3: -A bacteria called Propionibacterium shermanii produces Swiss cheese. The big holes in this cheese are caused by the bacterium producing a high amount of CO. The bacterium responsible for openings for all aims and capacities is Propionibacterium Sharmani or P. Sharmani.
Detailed explanation-4: -Contrary to what cartoons have suggested over the years, the holes are not made by mice eating their way through the cheese. And nor are they produced by carbon dioxide released by bacteria, as popular scientific belief held. Instead, a Swiss laboratory says they are created by flecks of hay.
Detailed explanation-5: -Swiss cheese and its characteristic holes created by the action of Propionibacterium freundenreichii bacteria.
