Question
Industrial fermentation is the use of microbial fermentation to make products useful to humans such as bread, beer, wine, cheese, biofuel and sewage treatment.
•Describe one example of industrial fermentation.
•Your description should list the reactants (inputs), products (output), and organism used.
•Be as specific as possible. For example, different cheese are made using different microorganisms and slightly different ingredient.
•Lastly, explain the advantages and disadvantages of a microorganism using fermentation to generate energy compared to aerobic respiration.
Explanation / Answer
Industrial fermentation is the intentional use of fermentation by microorganisms such as bacteria and fungi as well as eukaryotic cells like CHO cells and insect cells, to make products useful to humans. Fermented products have applications as food as well as in general industry. Example: Baking industry. The baking industry relies on industrial production of its ingredients, including baking yeasts. Baker's yeast is the common name for the strains of yeast commonly used as a leavening agent in baking bread and bakery products, where it converts the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is also a single-cell microorganism found on and around the human body.
Water is mixed with flour, salt and the leavening agent. Other additions (spices, herbs, fats, seeds, fruit, etc.) are not needed to bake bread, but are often used to provide flavors. The yeast used for leavening bread is Saccharomyces cerevisiae. The mixed dough is then allowed to rise one or more times and then loaves are formed. The bread is then baked in an oven.
The important disadvantages of aerobic respiration are;
Aerobic respiration takes place only in the presence of oxygen.
It does not bring about a quick release of energy.
The main advantages of the aerobic respiration are;
Large amount of ATP production takes place during aerobic respiration.
The byproducts of aerobic respiration is not a harmful one, since they are carbon dioxide and water.
During aerobic respiration; the respiratory substrate is completely oxidized.
Aerobic respiration involves the process of exchange of gases between the living organisms and the environment.
