Explain how microbes are useful in pollution control and also in production of alternative source of energy.

Explanation

Microbes are major component of biological world on this earth . Although they are the causal agents of most of the infections diseases, still they are of great importance to humans.
Now , scientists are developing the ways in which the use of microorganisms is solving pollution problem . This can be done by bioremediation . In this technique, microorganisms are used to neutralise pollutants from a contaminated site by their oxidation .
(i) By enhancing the growth and activity of microbes already present an pollutant site .
(ii) By adding some new microbes to the pollution site . Pollution control by the application of microbes works best when pollutants are a known mixture of organic compounds that are related to each other in structure and when there is no competition from indigenous microorganisms .
