Metagenomics

Definition

Metagenomics is the study of genetic material recovered directly from environmental samples, allowing scientists to analyze the collective genomes of microorganisms present in a specific environment. This approach helps to identify and understand the diversity of microbial communities, their functions, and their roles in various processes, including bioremediation and ecosystem health.
