Accepted 18 June 2012 Coastal lagoons, both hypersaline and freshwater, are common, but still understudied ecosystems. We Published describe, for the first time, using high throughput sequencing, the extant microbiota of two large and 3 July 2012 representative Mediterranean coastal lagoons, the hypersaline Mar Menor, and the freshwater Albufera de Valencia, both located on the south eastern coast of Spain. We show there are considerable differences in the microbiota of both lagoons, in comparison to other marine and freshwater habitats. Importantly, a novel uncultured sulfur oxidizing Alphaproteobacteria was found to dominate bacterioplankton in the Correspondence and hypersaline Mar Menor. Also, in the latter prokaryotic cyanobacteria were almost exclusively comprised by requests for materials Synechococcus and no Prochlorococcus was found. Remarkably, the microbial community in the should be addressed to freshwaters of the hypertrophic Albufera was completely in contrast to known freshwater systems, in that F.R.V.
