“…The process of metal uptake and their accumulation by different plants depends on the concentration of the available metals in soils (Gupta and Sinha 2006). The available and exchangeable metal concentrations in rhizosphere soils determined at the end of the experiment are shown in Table 3.…”

In this work, we evaluated the ability of rhizobacteria isolated from a metal-contaminated site to produce plant growth-promoting substances, such as indole-3-acetic acid (IAA), ammonia, hydrogen cyanide, siderophores and extracellular enzymes, to solubilize phosphate and for 1-aminocyclopropane-1-carboxylate (ACC)-deaminase activity, while assessing their capacity to enhance Trifolium repens growth. The rhizobacteria that better performed were used as bioinoculants for plants grown in zinc-and cadmium-spiked soils. Rhizobacteria were inoculated onto white clover seedlings growing in 250 and 500 mg kg -1 of zinc and in 10 and 30 mg kg -1 of cadmium-spiked soils and plant traits determined. The available and exchangeable rhizosphere metal concentrations were analyzed. Twenty rhizobacteria stimulated white clover growth under axenic conditions. Overall, strains Rhodococcus erythropolis EC 34, Achromobacter sp. 1AP2 and Microbacterium sp. 3ZP2 increased clover biomass in the absence and in presence of metals; however, in soils with 250 mg kg -1 of zinc, bacterial inoculation did not enhance plant biomass. Biomass enhancement may be related to the multiple bacterial promoting traits, especially the production of high levels of IAA and siderophores and the activity of ACC-deaminase. To the best of our knowledge, this is the first study reporting the potential of R. erythropolis to increase plant growth in metal-contaminated soils. In general, strains Microbacterium sp. 3ZP2 and Arthrobacter sp. EC 10 enhanced the available and exchangeable metal concentrations in rhizosphere showing their potential to improve phytoremediation efficiency. This work clearly indicates that rhizobacteria are promising for the development of bioinoculants useful for phytoremediation of polluted soils.

“…Nutrients are essential for plant growth (Hanay et al, 2009;Singh and Sinha, 2004;Zhang et al, 2008), and the use of sewage sludge in agriculture to ameliorate the physicochemical deficiencies of degraded soil is a practice that is growing worldwide (Gupta and Sinha, 2006;Singh and Agrawal, 2007). Moreover, land application is considered one of the most economic and effective ways to dispose of sludge and supply plants with nutrients (Zhu et al, 2013).…”

“…A slower rate of interaction between DTPA and the target metal species irrespective of the temperature conditions or at neutral pH can thereby be assumed [18,20]. The lower pH of EDTA in solution is also mentioned as a reason for the lesser metal extraction capability of DTPA than the EDTA [37]. Such sub-standard metal-DTPA complex formation rate compared to the NTA or EDTA was also mentioned in the literatures [38,39].…”
