In the western Mediterranean, the Region of Murcia (SE Spain) is characterized by notable biodiversity and ecological heterogeneity, encompassing diverse habitats, including rocky shores, sandy beaches, seagrass meadows, and the Mar Menor, one of Europe’s largest hypersaline lagoons. Within these systems, marine yeasts play critical ecological roles in organic matter recycling and produce metabolites of biotechnological and medical interest. This study presents the first comprehensive survey of culturable marine yeasts from the Mediterranean coast of the Region of Murcia. From seawater and sediment samples, 415 strains were identified via ITS and LSU rRNA sequencing, revealing 90 species across 44 genera, including 78 known taxa and 12 potentially novel ones. Most isolates were assigned to the phylum Ascomycota (62%), primarily distributed among the classes Pichiomycetes, Dothideomycetes, Saccharomycetes and Dipodascomycetes, whereas Basidiomycota accounted for the remaining 38%, mainly comprising the classes Tremellomycetes and Microbotryomycetes. The genera most represented in both seawater and sediment were Rhodotorula and Candida, and approximately 10% of the isolates corresponded to stress-tolerant black yeast-like fungi (Aureobasidium spp., Hortaea werneckii, Exophiala oligosperma, and Zalaria alba), a group notable for its taxonomic novelty and valuable biotechnological traits. Culturable yeast assemblages displayed pronounced spatiotemporal variability, with diversity generally increasing during milder seasons and in areas influenced by anthropogenic activity, suggesting the combined effect of natural gradients and human-driven alterations. Representative strains exhibited broad enzymatic capabilities, producing extracellular cellulases, proteases, xylanases, amylases, chitinases, and pectinases, underscoring their ecological role in organic matter turnover and nutrient cycling. Our findings provide novel insights into the taxonomic composition and metabolic potential of marine yeast recovered from the Mediterranean Sea and set the basis for their future exploitation in industrial and environmental biotechnology."},"samplingDescription":{"studyExtent":"This dataset contains occurrence records and associated metadata for culturable marine yeasts isolated from seawater and sediment samples collected along the Mediterranean coast of the Region of Murcia, southeastern Spain. Sampling covered diverse coastal habitats, including rocky shores, sandy beaches, seagrass-associated environments, ports, the Mar Menor hypersaline lagoon, and salt pond systems, across four meteorological seasons. The dataset includes taxonomic identification, sampling site, season, sample type, geographic information and isolate-based abundance in a heterogeneous western Mediterranean coastal region.","sampling":"Field sampling was conducted along approximately 250 km of the Murcia coastline, southeastern Spain, Western Mediterranean Sea, from autumn 2024 to summer 2025. Seawater and sediment samples were collected seasonally at ten coastal sites representing different geomorphological features and environmental gradients. At each site, seawater samples of 3 L and sediment samples of 100 g were collected in triplicate at surface level using sterile glass containers.","methodSteps":["Seawater samples were processed by filtration of 1 L through 0.45 µm membranes. Sediment samples were processed by resuspension of 10 g sediment in sterile saline solution, followed by filtration and culture-dependent isolation. To complement the filtration procedure and enhance the recovery of viable yeasts potentially present at low concentrations, an enrichment protocol was also applied. Yeast and yeast-like colonies were purified, preserved, and identified using ITS and/or LSU rDNA sequencing."]},"countryCoverage":[],"collections":[],"dataDescriptions":[],"dataLanguage":"eng","acknowledgements":"<p>&lt;p&gt;This study forms part of the ThinkInAzul programme and was supported by MICIU with funding from the European Union NextGenerationEU programme (PRTR-C17.I1) and by Comunidad Autonoma de la Region de Murcia-Fundacion Seneca.
