    Relative distributions of BTEX and alkanes (Fig. S1), PCoA of distances between assA sequences present in the sediment samples collected from marine sediments (Figueiras beach, Rodas beach, and Mallorca) and sequences available in the databases (Fig. S2), rarefaction curves of the BssA-like sequences from sediments samples (Fig. S3), alignment of the consensus sequences of the different clusters determined in the study showing the frequency profiles of amino acids at each position (Fig. S4), unidentified clusters found in our analysis (Fig. S5), BssA-like sequences retrieved form the databases and used in the analysis (Table S1), BTEX and PAH compositions in the sediment samples (Table S2), most probable number of aromatic degrading bacteria in the Mallorca sediment microcosms and Atlantic Islands sediments (Table S3), and specificity of the bssA probe in each sample (Table S4).
