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.
