Advances in metagenomic sequencing technologies enabling the study of microbial communities

Metagenomic sequencing has revolutionized microbial ecology by enabling culture-independent analysis of complex microbial communities. Recent advancements in sequencing technologies, computational tools, and functional annotation pipelines have dramatically improved resolution, accuracy, and scalability. This review explores the evolution of metagenomic platforms (e.g., short-read, long-read, and single-cell sequencing), their applications in diverse ecosystems (human gut, environmental, industrial), and persistent challenges such as data integration and bias correction. We highlight emerging trends, including portable sequencing devices and CRISPR-based enrichment, that promise to democratize metagenomic research further.
