Phytomediated Biostimulation of the Autochthonous Bacterial Community for the Acceleration of the Depletion of Polycyclic Aromatic Hydrocarbons in Contaminated Sediments

Figure 3

Fractional copy numbers of GN and GP PAH-RHDα transcripts at the different time-points of analysis in vegetated sediments. Histogram values represent mean + SE of the 6 parallel samples. The same letters on the bars indicate values not significantly different at . NsV6: N spiked and vegetated sediments after 6 months of incubation; NsV9: N spiked and vegetated sediments after 9 months of incubation; NsV12: N spiked and vegetated sediments after 12 months of incubation. (a) Rhizospheric portion of vegetated sediments; (b) bulk portion of vegetated sediments; (c) root endophytic bacterial population of P. australis plants.
