Metagenomics is the science of study of the cumulative genomes of several species of organism that grow and communicate in a particular environmental condition. Metagenomics can be utilized to recognize and differentiate new species more rapidly and efficiently and also help in examining the consequence of pollutants on the environment.
Metagenomics has revolutionary application because it took over the practice of using pure cultures. Pure cultures are used to study particular and individual species in the laboratory. However, it does not precisely show what happens in the environment.
