Question

describe the method of production of ethanol by fermentation reaction​

Answer 1

Answer:

Explanation:

Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process. It also takes place in some species of fish (including goldfish and carp) where (along with lactic acid fermentation) it provides energy when oxygen is scarce.[1]

Ethanol fermentation has many uses, including the production of alcoholic beverages, the production of ethanol fuel, and bread cooking.

Answer 2

Answer:

Ethanol is produced in a large scale by the fermentation of molasses (sugarcane juice) . In this process enzymes such as invertase and zymase are used which are present in yeast .It is carried out in a vessel at 20°-30°C which allows carbondixide released to move out,but at the same time prevents air from entering into it.

During fermentation ,sugar and starch molecules are broken down into smaller molecules containing ethanol with evolution of CO2 gas. Ethyl alcohol is separated by fractional distillation.
