Question

Give an example to prove that microbes release gases during metabolism.

Answer 1

Microbes are tiny, unicellular organisms invisible to the naked eye. They are also known as microorganisms or microscopic organisms, as they can only be seen under a microscope. They make up almost 60% of the living matter of the earth.

Complete answer:
Bacteria and fungi perform the fermentation process and release carbon dioxide during this process. Fermentation is the process of converting a complex organic substance to a simpler substance with the action of bacteria or yeast. Sugar fermentation produces alcohol with the release of carbon dioxide and very little energy.

Fermentation in food processing is the process of converting carbohydrates into alcohol or organic acids using microorganisms, yeasts or bacteria under anaerobic conditions. Fermentation usually means that the action of the microorganisms is desired. The fermentation science is known as zymology or zymurgy.

Other widely used fermented foods include vinegar, olives and cheese. More localized foods prepared by fermentation may also be based on beans, grains, vegetables, fruit, honey, dairy products and fish.

Microbes perform lactic acid fermentation (anaerobic respiration) and produce carbon dioxide and lactic acid. The puffy appearance of Idli and Dosa dough is caused by microbes released by carbondixoide during fermentation. In the same way, the baking industry uses Baker's yeast, which causes the rise of cakes and pastries during the process. It is also due to the release of carbon dioxide during lactic acid fermentation.

Note: Food fermentation serves five main purposes: to enrich the diet through the development of a variety of flavors, aromas and textures in food substrates; to preserve large amounts of food through lactic acid, alcohol, acetic acid and alkaline fermentation; to enrich food substrates with proteins, essential amino acids and vitamins; to eliminate anti-nutrients; and to reduce cooking time and vitamin content.
