Micrococcus sp. MU1 and Klebsiella sp. BAM1 are species of cad- mium-resistant PGPR that effectively increased cadmium solubili- zation in cadmium-supplemented soil and promoted H. annuus root elongation at toxic concentrations of cadmium. Increases in the plant dry weight and cadmium accumulation in H. annuus planted in cadmium-polluted soil was observed after inoculation with Micrococcus sp. On the other hand, Klebsiella sp. promoted the translocation of cadmium from the roots to the shoots of H. annuus. These findings clearly demonstrate that these plant– microbe interactions were efficacious in promoting plant growth and cadmium uptake in H. annuus. Micrococcus sp. and Klebsiella sp. also improved the cadmium phytoextraction efficiency of H. annuus planted in polluted soils. The synergistic interactions between plants and rhizobacteria along with coupling phytoex- traction and soil bioaugmentation are important strategies to clean-up heavy metal-contaminated soil.
