Abstract

Since its discovery in 1998, representatives of the extremely halophilic bacterium Salinibacter ruber have been found in many hypersaline environments across the world, including coastal and solar salterns and solar lakes. Here, we review the available information about the distribution, abundance and diversity of this member of the Bacteroidetes.

Phylogenetic reconstruction based on 16S rRNA gene sequences from isolates and clones affiliated to Bacteroidetes. The tree is based on the results of a maximum likelihood analysis and shows quarter puzzling support values. Bar, 10% estimated sequence divergence. Accession numbers of individual sequences are shown on the tree. Sequences retrieved from hypersaline environments are labelled with H. Modified from [22].

The m/z values having a high correlation with geographical origin are highlighted in red, blue or green while the nondiscriminating masses are represented in yellow.
