Give examples to prove that microbes release gases during metabolism.

उत्तर
There are numerous examples indicating that microorganisms emit gases during their metabolism. Examples are as follows:
- Bacteria ferment the dough required to make dosa and idlis. The puffy appearance of dough is related to the generation of CO2 during the fermentation process.
- Swiss cheese is distinguished by its characteristic flavour and large holes. The large holes are caused by the amount of CO2 produced by the bacterium Propionibacterium shermanii.
