Metagenomics is the study of genetic material recovered directly from environmental samples. It allows scientists to analyze the collective genomes of microorganisms in a specific habitat, such as soil, water, or the human gut, without the need to culture them in a lab. This approach provides insights into the diversity and functions of microbial communities. By using advanced sequencing technologies, researchers can identify and characterize the vast array of microbes present in a sample. Metagenomics has applications in various fields, including ecology, medicine, and biotechnology, helping to understand microbial roles in health, disease, and ecosystem functioning.
