Abstract
In this work, metabarcoding of 16S and 18S rRNA gene coding sequences were employed to characterize the prokaryotic and eukaryotic communities across the salinity gradient (3.5, 7.8, 14.4, and 31.8% NaCl) in Odiel salterns, located in the city of Huelva (SW Spain). Coastal salterns are excellent environments to study the dynamics of the microbiota across the salinity gradient since we find from seawater, the most abundant ecosystem on Earth, to crystallization pools, one of the most extreme. Diverse harsh conditions converge in solar salterns, including high salt concentration, temperature, and solar irradiance. Most environmental factors are similar in the different ponds that comprise the salterns, excepting salinity, which increases through the series of ponds until reaching saturation concentrations. Understanding the microbiology of these ponds is important for the salt production process, given that this microbiota can physically affect the evaporation process and chemically interact with dissolved ions. In addition, these microorganisms are crucial in these ecosystems, supporting bird populations, and potentially a source of enzymes and useful carotenoids for many biotechnological applications.
