Figure 4.

Read recruitments (< 95% N-identity) of reconstructed draft genomes and a reference draft genome from the genus Thioalkalivibrio from different metagenomic datasets. SP-37 and SP-19 are metagenomes from a crystallizer and an intermediate saline pond of the solar saltern in Santa Pola, Spain, with 37 and 19%, salinity respectively (Ghai et al., 2011). The salinity (in %) for the different soda brine metagenomes is given between brackets. Reconstructed draft genomes encoding putative chitinases are marked in the figure legend with a circle, those encoding putative cellulases with a triangle. RPKG, Reads Per Kilobase of sequenced reads per Gigabase of mapped reads. (A) Putative organisms with relatively high abundance (> 150 RPKG), (B) with moderate abundance, (C) and with relatively low abundance (< 20 RPKG).
