  "abstract": "Mineral springs of the Northern Caucasus remain largely uncharacterized by culture-independent approaches. At the high-altitude Dzhily-Su spring complex, where isotope data indicate deep-seated magmatic fluid inputs, planktonic and sediment-associated communities were analyzed using 16S rRNA gene profiling to determine whether these inputs shape the local microbiome. Rather than a distinct magmatically influenced community, the results revealed a pronounced water-sediment partitioning of taxa with known iron-cycling representatives, microaerophilic Gallionellaceae dominating the water fractions and facultatively anaerobic Aeromonas and Shewanella dominating the sediments. Furthermore, analysis of the fine-size (0.22 µm) water fraction highlighted a notable enrichment of candidate lineages and archaea, including a prominent Nanoarchaeota population (58.6% of archaeal reads) lacking identified mesophilic hosts. The predominance of a typical neutrophilic iron-cycling assemblage, together with the observed water-sediment partitioning, is consistent with an important role of local physicochemical gradients in structuring the microbial community despite the unusual geochemical setting of the parent aquifer.",
