“…Soil rhizobacteria, with activity and a high surface area-to-volume ratio because of their small size and therefore providing a large contact area, may have the potential to act as microbial chelates associated with phytoremediation (Anderson et al, 1993;Kärenlampi et al, 2000;Sitaula et al, 1999). Indian mustard plants germinated on Se-containing media from axenic seeds coated with bacteria produced more root hairs and accumulated more Se than plants grown from axenic seeds (de Souza et al, 1999a).…”

Heavy metal pollution of soil is a significant environmental problem and has its negative impact on human health and agriculture. Rhizosphere, as an important interface of soil and plant, plays a significant role in phytoremediation of contaminated soil by heavy metals, in which, microbial populations are known to affect heavy metal mobility and availability to the plant through release of chelating agents, acidification, phosphate solubilization and redox changes, and therefore, have potential to enhance phytoremediation processes. Phytoremediation strategies with appropriate heavy metal-adapted rhizobacteria have received more and more attention. This article paper reviews some recent advances in effect and significance of rhizobacteria in phytoremediation of heavy metal contaminated soils. There is also a need to improve our understanding of the mechanisms involved in the transfer and mobilization of heavy metals by rhizobacteria and to conduct research on the selection of microbial isolates from rhizosphere of plants growing on heavy metal contaminated soils for specific restoration programmes.

“…After that, uptake process assimilates and a store metal in plants and after that direct or indirect intake by human population occurs. According to Karenlampi et al [5] metals are dangerous in the event that they are available at expanded levels of bioavailability for example essential (Mn, Zn, Cu, Mo, Fe, Ni) and non-essential metals (Pb, Cd, Cr, Hg). Metal hyper aggregating discovery properties in certain plants expressed that it might be conceivable to utilize these plants for the cleanup of heavy metal pollution in soil and water.…”

“…Plants may also be used to remove contaminants from soil by phytoextraction and then harvested for processing [8][9][10][11]. There are some promising results suggesting that these techniques might become practical alternatives to mechanical and chemical approaches in remediation of metal contaminated soils [5]. Recently, rhizoremediation objective is to upgrade and develop innovative, economical, and environmentally compatible approaches to remove heavy metals from the environment.…”

Cadmium (Cd) is a metal that contaminates the environment mainly through agroindustrial, metallurgical and chemical industrial activities. It can affect mineral absorption by plants, the stomatal aperture, photosynthesis and water balance by reducing the crop yield. Aiming at the discovery of new species able to tolerate Cd, this study evaluated the germination and development of jackbean plants in the presence of Cd to determine whether there is tolerance to this metal. Seeds and seedlings of this species were grown in plastic pots containing sand with Cd concentrations of 0, 500 and 2000 µmol L -1 applied as CdCl 2 .2.5H 2 O. The experiments were conducted in a greenhouse under natural photoperiod conditions. Percent germination was close to 100% 13 days after sowing. Seedlings accumulated much of the applied Cd in the shoot and produced high biomass. No alterations to the photosynthetic apparatus were observed at the lower concentrations. This indicates that jack bean plants exhibit characteristics of tolerance to Cd and that further studies should be performed to report if this species can be used as phytoremediator. RESUMO: O cádmio (Cd) é um metal que contamina o ambiente principalmente por meio das atividades agroindustriais, metalúrgicas e químicas. Ele pode afetar a absorção de minerais pelas plantas, a abertura estomática, a fotossíntese e o balanço hídrico diminuindo a produção vegetal. Visando à descoberta de novas espécies capazes de tolerar o Cd
