Metagenomics is a branch of molecular biology that involves the direct study of genetic material obtained from environmental samples, without isolating and culturing individual microorganisms. It enables the analysis of the entire microbial community present in a specific habitat, including bacteria, archaea, viruses, and fungi. Traditional culture-based methods can identify only a small percentage of microorganisms, whereas metagenomics allows the exploration of both culturable and unculturable microbes through advanced DNA sequencing techniques. With the development of next-generation sequencing technologies, metagenomics has become a powerful tool to study microbial diversity, community structure, and functional genes in environments such as soil, oceans, and the human gut. This approach has significant applications in environmental science, agriculture, biotechnology, and medical research, particularly in understanding microbial interactions and their role in health and disease.
