Geographic localization of metagenomic sequences with high similarity to P. salivibrio 16S rRNA. The point west of South America indicated by an arrow was for a metagenomic sample taken from a hypersaline lagoon (63.4 psu) at 0.2 m depth in the Galapagos Islands. The DnaE metagenomic sequence shown in Fig. 2 also came from this site. The star is the site of isolation of P. salivibrio CL-TW6T. The figure was produced by the Ocean Data View Tool (see Methods)
