Reconstrucción de 2.965 genomas microbianos de sedimentos de manglares en Guangxi, China

Mangrove sediments, being organic-rich and anoxic, host diverse and functionally important microorganisms that play crucial roles in global biogeochemical cycling. In order to characterize this diversity at the genome-resolved level, we collected 38 sediment samples encompassing both surface (0-5 cm) and core (up to 90 cm) depths from six representative mangrove sites across Guangxi Province, China. Using a standardized pipeline for assembly, binning, and dereplication, we reconstructed 2,965 non-redundant metagenome-assembled genomes (MAGs), comprising 2,383 bacterial and 582 archaeal genomes spanning 78 microbial phyla. This dataset captures the high microbial diversity and functional potential within mangrove sediments under variable environmental conditions. It provides a valuable genomic resource for investigating the structure, metabolism, and ecological roles of sediment microbial communities in intertidal, nutrient-rich ecosystems, supporting future studies on microbial adaptation and biogeochemical cycling in global blue carbon environments.
