- Sugarcane
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Ethyl alcohol is commercially manufactured from sugarcane. Molasses is the byproduct of sugar industry. Ethanol is produced by the fermentation of molasses (contains glucose and fructose) by using yeast, Saccharomyces cerevisiae.
$\underset{\text{Glucose or Fructose}}{C_6H_{12}O_6} {->[{\text { Zymase }}][{\text { (Yeast cell) }}]} \underset{\text{(Ethyl alcohol)}}{2 C _{2} H _{5} OH} +2 CO _{2}$
Bajra and maize are not used for manufacturing alcohol. Grapes are also used for formation of alcohol but not used commercially.

Concepts Used:
Microbes in Human Welfare
There are several valuable microorganisms that are beneficial to humans in various manners such as:
In Household Products
- Fermentation of milk to produce yogurt.
- Milk cuddling to compose curd, cheese, and paneer.
In Industrial Products
- Production of beverages such as wine, beer, whiskey, brandy, or rum.
- Production of antibiotics such as Penicillin and other chemical substances to kill or retard the expansion of disease-causing microbes.
Fermented Beverages
- A fermentor is used to produce microbes on a large scale for industrial purposes.
- The brewer’s yeast (Saccharomyces cerevisiae) is used to make ethanol. At this time, the yeast ferments malted cereals and fruit juices.
Antibiotics
- The term antibiotic means “against life”. These materials can kill or destroy the growth of other microbes.
