Question

list out the various ways, fermentation process is used in our daily life​

Answer 1

Answer:

Fermentation is the process by which microorganisms convert sugar to acids or alcohol in the absence of oxygen.

Yogurt and curd are made using fermentation of milk by bacteria such as Streptococcus and Lactobacillus species. Alcoholic beverages like beer, wine, brandy, whisky etc are made using fermentation of grains, grapes, rice etc by yeast. Bread is also made by fermenting dough using yeast. Gasohol is a fuel made using gasoline and alcochol which involves fermentaion too. Apart from these, fermentation is also used in the preparation of certain medicines.

1. Lactic acid fermentation is another type of fermentation and is described as the metabolic process that transforms sugar into the metabolite lactate and energy. It is the only respiration process that does not produce a gas and occurs in some bacteria (such as lactobacilli) and muscle cells.

Lactic acid fermentation is used to flavor or preserve dairy and vegetables. Lactic acid fermentation also occurs in muscle cells under strenuous activity. In this case, muscles consume energy (ATP) faster than oxygen can be supplied, resulting in an anaerobic environment and thus lactic acid buildup and sore muscles.

2. Ethanol fermentation is defined as the biological process that turns sugar (glucose, fructose and sucrose) into ethanol, carbon dioxide and energy.

After the initial glycolysis step that converts one glucose molecule to two pyruvate molecules, the pyruvate molecules further break down into two acetaldehyde and two carbon dioxide molecules, a step catalyzed by pyruvate decarboxylase. Alcohol dehydrogenase then facilitates the conversion of the two acetaldehyde molecules to two ethanol molecules, utilizing the energy and hydrogen from NADH.
