摘要

Almost 70% of Earth’s surface is covered by marine environment, which hosts diverse microbial populations that remain largely unexplored due to limitations in traditional culturing techniques. Advances in high-throughput sequencing technologies have enabled the classification and characterization of these unculturable marine microbes. This review explores the use of marine microbial metagenomics, emphasizing its interdisciplinary nature such as integrating molecular biology, computational tools, and ecological insight for identifying novel microbial populations in marine environments. Some marine microbes possess certain unique genes with potential applications in synthesizing bioactive molecules and bioremediation agents. Metagenomic studies provide valuable insights into microbial roles in biogeochemical cycles environmental monitoring, discovery of novel bioactive compounds, and the detection of antibiotic resistance genes (ARGs) and potential pathogens, highlighting the importance of exploring marine microbial diversity. The review also addresses emerging challenges in data interpretation and integration. Overall, the review emphasizes the significance of marine metagenomics in advancing ecological understanding and supporting sustainable innovations in marine science and biotechnology.
