“…The TI values on shoot length basis of inoculated plants were 81%, 69%, and 53% under 100 mg kg -1 , 200 mg kg -1 , and 300 mg kg -1 , respectively, whereas TI values on root length basis in the case of inoculated plants were 61%, 53%, and 49% under 100 mg kg -1 , 200 mg kg -1 , and 300 mg kg -1 , respectively. Some other studies also reveal the augmented TI in microbe-assisted mustard plants [34].…”

During our current study we evaluated the effect of ethylenediaminetetracetic acid (EDTA) and Enterobacter sp. CS2 on nickel stress alleviation and phytoextraction by Impatiens balsamina L in spiked soil. Nickel resistant Enterobacter sp. CS2 was isolated from soil polluted by industrial effluents. The I. balsamina seeds primed with Enterobacter sp. CS2 were raised in EDTA-supplemented soil (10 mM) contaminated with 0, 100, 200, and 300 mg kg -1 Ni for 50 days. The effect of different treatments on plant growth attributes, nickel tolerance index, bioconcentration factor, and translocation factor were evaluated. The Ni stress reduced plant growth, carotenoids, and chlorophyll (chl) content. However, higher Ni uptake and proline contents were observed in plants growing in Ni-contaminated soils. The Enterobacter sp. CS2 inoculation further enhanced Ni uptake and proline contents in I. balsamina plants growing under Ni stress. The inoculated plants showed improved shoot length, root length, carotenoid content, chl 'a' and 'b' contents, root and shoot dry weight. The Ni tolerance index in Enterobacter sp. CS2-assisted plants was much higher compared to un-inoculated ones. The inoculated plants supplemented with EDTA enhanced 39%, 34%, and 30% Ni uptake in roots respectively under 100, 200, and 300 mg kg -1 of Ni treatment as compared with un-inoculated plants. The data regarding bioconcentration factor and translocation factor showed that Ni phytoextraction capability of I. balsamina plants was significantly enhanced with the supplementation of Enterobacter sp. CS2 and EDTA.

“…A rising number of studies have demonstrated the application of Indian mustard and rapeseed in the phytoextraction of heavy metals, due to their capacity to accumulate high levels of Zn, Cu, Cd, and Se (Kuiper et al 2004; Ariyakanon and Winaipanich 2006; Grispen et al 2006; Chauhan and Rai 2009). Similarly, Chekol and Vough (2001), Kaimi et al (2007), Fan et al (2008), and Marti et al (2009) depicted alfalfa as a potential phytoremediator of organic contaminants, as well as its ability to germinate in petroleum-contaminated soil.…”

“…Due to this fact, alternative biological clean-up methods, such as bioremediation and phytoremediation, have raised much interest in the last two decades. Moreover, a reasonable combination of both techniques is reflected by an emerging number of studies that utilize the natural degradation abilities of plants and plant-associated microorganisms to remove organic pollutants or heavy metals from the polluted environment (Liste and Felgentreu 2006; Gaskin et al 2008; Lin et al 2008; Chauhan and Rai 2009; Tang et al 2010). Rhizoremediation is a successful, cost-effective and environmentally friendly approach that is based on pollutant degradation to non- or less-toxic compounds by microorganisms in the rhizosphere.…”

Rhizoremediation is a complex type of green clean-up technology that involves both plants and the rhizosphere-associated microorganisms to decompose hazardous compounds. The success of the strategy strongly depends on plant tolerance towards the pollutant, as well as plant's interactions with the rhizospheric microbes. The microorganisms may be stimulated by the secreted root exudates, which results in an increased breakdown of contaminants in the rhizosphere. The main goal of this study was to establish a potential rhizoremediation combination for a diesel-polluted site. Inoculation of plant roots or seeds with indigenous rhizospheric populations is a common approach in the rhizoremediation. However, we introduced hydrocarbon-degrading consortia (M10, R3, and K52) that were previously isolated from crude oil-contaminated soil instead of indigenous microbes. Bioaugmentation with these petroleum degraders was applied to screen four high biomass crop species (Indian mustard, alfalfa, high erucic acid rapeseed, HEAR, and low erucic acid rapeseed, LEAR) for their tolerance towards diesel oil. At no pollution, a promoting effect of M10 bacteria could be observed on germination and root elongation of all plant species. Moreover, M10 consortiums increased the germination index at 6,000 mg diesel oil per kilogram dry soil in the case of Indian mustard, alfalfa, and HEAR. The latter species was found to increment its dry weight upon bioaugmentation with M10 bacteria and all diesel oil treatments (6,000 and 24,000 mg diesel oil per kilogram dry soil). The initial results indicate HEAR and the M10 bacterial consortium as a promising plant–microbe tandem for a long-term rhizoremediation process.Electronic supplementary materialThe online version of this article (doi:10.1007/s11270-013-1676-0) contains supplementary material, which is available to authorized users.
