Metagenomic Analysis

Definition

Metagenomic analysis is a technique used to study the genetic material obtained directly from environmental samples, allowing researchers to identify and characterize microbial communities without the need for culturing individual species. This approach provides insights into the diversity, function, and interactions of microorganisms in their natural habitats, which is particularly important for understanding their roles in processes like bioremediation.
