Cultured isolates with matching HTS sequences.

Columns show the isolates’ closest relatives according to the BLAST results, the percentage of identity with the BLAST reference strain (identity BLAST), the GenBank accession number of the BLAST reference strain, the number of HTS reads matching the isolate sequences in the surface sample (Reads in Surface), the percentage of the total HTS reads in the surface sample represented by the isolate sequences (% Surface), and the number of isolates of each taxa sequenced. Abbreviations are: Actino (Actinobacteria), Bact (Bacteroidetes), Alpha-P (Alpha-Proteobacetria) and Gamma-P (Gamma-Proteobacteria).
