Over the last decades, the biogeography of bacterial communities became a key topic in Microbial Ecology. Regarding land water, most of the studies are gathered in the northern hemisphere, leaving a gap in the knowledge about the patterns of bacterial diversity as a whole. It is quite troubling especially for South America, considering it contains about one-third of the total global water sources. In this work we compiled sequencing data of bacterial communities from South American, presenting the µSudAqua[db]. It contains over 870 metabarcoding samples, from 10 different ecoregions, with the georeferentiation and additional metadata. For its integration and validation we constructed a curated database (µSudAqua[db.sp]) using those samples sequenced by Illumina MiSeq with the commonly used primers proposed by Herlemann et al., (2011). This database comprised ~60% of the samples. This work was made in the framework of the µSudAqua collaborative network and represents the most complete databases of land water bacterial communities from South America freely available at https://microsudaqua.netlify.app.
