A laboratory experiment is described concerning the evaluation of the effects of combined treatments on the efficiency of lead phytoextraction by Brassica juncea grown in a Pb contaminated soil. In particular, biaugmentation with PGPR followed by soil addition with both EDTA and the non-ionic surfactant Triton X was compared with the treatment consisting in bioaugmentation and amendment with the sole EDTA. The combination of the bioaugmentation strategy with the addition of both EDTA and Triton X sorted better phytoextraction results with respect to the protocol based on the bioaugmentation of PGPR and the soil treatment with only EDTA.
