Question

Ethanol is commercially produced through a species of?

Answer 1

Hint: Ethanol is a chemical compound that is organic in nature. Ethanol is a colourless, toxic, flammable liquid with a distinct odour.

Complete answer:
Ethanol is produced by the microbial fermentation of sugar. Currently, microbial fermentation only works with sugars. Starch and cellulose, two major components of plants, are both made of sugars and can, in theory, be converted to sugars for fermentation.
Ethanol is an important industrial chemical; it is used as a solvent, in the synthesis of other organic chemicals, and as a gasoline additive. Many alcoholic drinks, including beer, wine, and distilled spirits, contain ethanol as an intoxicating ingredient.
Ethanol is commercially manufactured by a specific species of Saccharomyces. One of the most essential characteristics of ethanol-producing yeast is ethanol tolerance.
The aim of this study was to improve the ethanol tolerance of Saccharomyces cerevisiae. Ethanol is a common renewable biofuel. To increase the availability of this alternative energy source, ethanologenic yeasts that can produce ethanol more efficiently are needed.
During ethanol fermentation, yeasts are subjected to a variety of stresses, including increased ethanol, toxic by-product inhibition, high temperature, and osmotic pressure from high substrate sugar concentrations.
Ethanol is commercially produced through a species of Saccharomyces cerevisiae.

Note:
Industrially processed ethanol is made by reacting ethene with steam. Strong silicon dioxide coated with phosphoric (V) acid is used as the catalyst. The reaction can be reversed. At each pass through the reactor, only $5\%$ of the ethene is converted into ethanol.
