Fermentation is the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.   The two most common types of fermentation are (1) alcoholic fermentation (and)  (2) lactic acid fermentation.   (1) Alcoholic fermentation : the type of fermentation in which ethyl alcohol is the main end product .This is very common in yeast (unicellular fungus) and also seen in some bacteria. Yeast cells release enzymes called zymase complex which bring about the fermentation. The reactions are similar to anaerobic respiration.   (2) Lactic acid fermentation : The type of fermentation in which lactic acid is the end product. It is carried out by some bacteria (e.g. lactic acid bacteria), and also by animals (muscle glycolysis in animals, under oxygen deficiency, results in the formation of lactic acid this is whay we experience in muscle cramps, or "Charley horse").

Demand-side market failures happen when demand curves do not reflect consumer’s full willingness to pay for goods or services. Supply-side market failures occur when supply curves do not reflect the full cost of producing a good or services.
