The characterization of marine microbiomes can provide valuable information for evaluating the sustainability of coastal waters that are increasingly subjected to environmental and human impacts. Our study is the first metagenomic study realized on Moroccan Mediterranean coastal seawater. We analyzed and described the Gibraltar Detroit marine microbiome taxonomic and functional profiling using MG-RAST software. Shotgun sequencing revealed a predominance of bacterial taxa, particularly the Proteobacteria (57.29%) and Bacteroidetes (27.06%) phyla, alongside notable populations of eukaryotes, viruses, and archaea. Alphaproteobacteria and Gammaproteobacteria emerged as the dominant bacterial classes, while Flavobacteria represented a significant portion of Bacteroidetes. Functional profiling of the microbial community highlighted a wide array of metabolic pathways, emphasizing genes related to carbohydrate metabolism, amino acid synthesis, and protein processing. The marine microbiome exhibited essential biogeochemical activities, particularly in nitrogen, sulfur, and carbon cycles, with notable pathways including denitrification, thiosulfate oxidation, and carbon fixation. This functional diversity underlines the microbiome’s role in sustaining ecosystem health through nutrient cycling and organic matter degradation. Our findings offer a crucial baseline for understanding microbial community structure and resilience in Mediterranean coastal ecosystems, with implications for assessing future environmental and anthropogenic impacts on these microbial dynamics.}, organization = {EU MicroB3 project, funded by the European Union’s Seventh Framework Programme (FP7; Joint Call OCEAN.2011-2: Marine microbial diversity-new insights into marine ecosystems functioning and its biotechnological potential) under grant agreement no. 287589 (Ocean Sampling Day (OSD) Consortium)}, organization = {US NIH grant recipient through the H3abionet/H3africa consortium U24HG006941 and the OSD coordinator for Morocco}, organization = {internship at the Water Institute, Granada, Spain, for the 2022/23 academic year}, publisher = {MDPI}, keywords = {Mediterranean Sea}, keywords = {bacterial diversity}, keywords = {marine microbiome}, title = {Metagenomic Analysis of Microbial Diversity in the Moroccan CoastalWater of the Gibraltar Strait}, doi = {10.3390/w16223202}, author = {Chrairi, Manal and Barrijal, Said and Castellano-Hinojosa, Antonio and Boumait, Youssra and El Hamouti, Chahrazade and Lamzouri, Afaf and Ghazal, Hassan and Chahboune, Rajaa}, }
