The biogeography of bacterial communities is a key topic in Microbial Ecology. Regardingcontinental water, most studies are carried out in the northern hemisphere, leaving a gap onmicroorganism’s diversity patterns on a global scale. South America harbours approximatelyone third of the world’s total freshwater resources, and is one of these understudied regions.To fill this gap, we compiled 16S rRNA amplicon sequencing data of microbial communitiesacross South America continental water ecosystems, presenting the first databaseμSudAqua[db]. The database contains over 866 georeferenced samples from 9 differentecoregions with contextual environmental information. For its integration and validationwe constructed a curated database (μSudAqua[db.sp]) using samples sequenced by IlluminaMiSeq platform with commonly used prokaryote universal primers. This comprised ~60% ofthe total georeferenced samples of the μSudAqua[db]. This compilation was carried out inthe scope of the μSudAqua collaborative network and represents one of the most completedatabases of continental water microbial communities from South America.
