Question

How is soil pollution controlled by microbes?

Answer 1

1. Acid rain is rainwater containing harmful amounts of sulphuric acid and nitric acid.
2. Some species of bacteria like Acidiphilium and Acidithiobacillus ferrooxidans, use sulphuric acid as a source of energy.
3. Introduction of such bacteria in soil polluted by acid rain can make the soil fertile again.
4. Also, soil pollution occurring due to chemical fertilizers can be prevented due to use of these microbial inoculants.
