Metagenomic Sequencing -NGS
A metagenome is a collection of the total genetic material of a mixed community of organisms, such as environmental and human metagenomes. It contains genomes of both cultivatable and uncultivatable microorganisms. Shotgun metagenomic sequencing with NGS enables the study of these intricate genomic landscapes embedded in environmental samples by providing more than taxonomic profiling, giving also granular insights into species diversity, abundance dynamics, and complex population structures. Beyond taxonomic studies, shotgun metagenomics also offers a functional genomics perspective, enabling the exploration of encoded genes and their putative roles in ecological processes. Finally, the establishment of correlation networks between genetic elements and environmental factors contributes to a holistic understanding of the intricate interplay between microbial communities and their ecological background. In conclusion, metagenomic sequencing stands as a pivotal instrument for unravelling the genomic intricacies of diverse microbial communities, illuminating the multifaceted relationships between genetics and ecology within these complex ecosystems.
