FIGURE 6.

Taxonomic diversity of the Cullars metagenomic library and of the original soil sample used for library construction. Soil PCR: 16S rRNA gene PCR amplification of DNA isolated from the original Cullars soil sample used to construct the library; Library PCR: 16S rRNA gene PCR amplification of the DNA template from all metagenomic library clones pooled together; Library NGS: In sillico mining for 16S rRNA genes from the metagenomic library NGS contigs. The phyla contained in the section “Other phyla” are: RCP2-54, SAR324, Spirochaetes, Sumerlaeota, WPS-2; all with relative frequencies below 0.05%.
