“…1). These results were in line with some earlier studies who reported that EDTA addition to soil decreases the viability and number of AMF in the rhizosphere soil, although it is not lethal to the fungus (Marques et al, 2008;Tanwar et al, 2013).…”

This study was conducted to evaluate the effects of combination of ethylene diamine tetra acetic acid (EDTA) with arbuscular mycorrhizal fungi (AMF) on arsenic (As) phytoremediation using maize plants in pot experiment with four treatments (Control, EDTA, AMF, and EDTA+AMF). The results showed that lone addition of EDTA significantly increased exchangeable As concentration in the rhizosphere soil, and thus, enhanced plant uptake of As in shoots and roots. However, it markedly inhibited the root colonization, plant growth, and antioxidant enzyme activity. Consequently, As biological enrichment factor was the lowest because of reduced plant dry weight, although the plants possessed the highest As extraction efficiency. Unlike EDTA, AMF alone had a positive effect on root colonization, dry matter accumulation, and antioxidant enzyme activity, whereas negative effects of AMF on exchangeable As content in the rhizosphere soil and As uptake in shoots and roots were observed. However, using EDTA-AMF combination, maize plants simultaneously exhibited significantly higher exchangeable As extraction efficiency and biological enrichment factor, which were beneficial for the remediation of heavy metal-contaminated soil. Therefore, it is concluded that the EDTA-AMF combination could be regarded a promising choice for phytoremediation of heavy metal-polluted soil.

“…AM fungi provide an attractive system to advance plant-based environmental cleanup (G€ ohre and Paszkowski 2006). The adaptive mechanisms of AM symbiosis to contaminated soils and their contribution in HM bioremediation has been adopted and recommended by various researchers (Kapoor and Bhatnagar 2007;Garg and Kaur 2012;Tanwar et al 2013a). This is possibly due to the formation of a direct link between soil and plant roots through AM fungi during HM phytoremediation that enhances metal availability and promotes plant tolerance (Gaur and Adholeya 2004).…”

A pot trial using Glomus mosseae along with EDTA (ethylenediaminetetraacetic acid) was conducted for the phytoextraction of cadmium (Cd) by celery (Apium graveolens Linn.) plants from soil artificially contaminated with Cd under glass house conditions. The experiment is a 2 £ 2 £ 4 factorial design with two levels of G. mosseae inoculations (G. mosseae inoculated and uninoculated), two EDTA concentrations (without and with 2.5 mmol kg ¡1 soil EDTA) and four Cd concentrations (0, 5, 10, and 20 mg kg ¡1 soil). The results indicate the formation of an effective symbiosis between G. mosseae and celery in the contaminated soil. However, an increase in Cd input level and EDTA addition showed strong phytotoxic effect on celery plants and G. mosseae, as a considerable decrease in the frequency of root colonization and spore density was noticed. However, the plants were able to withstand the stressed condition due to the benefits provided by G. mosseae through increased P accumulation, chlorophyll content, and plant growth, resulting in an increase in Cd accumulation, which was good enough for the phytoextraction purpose. Thus, celery plants inoculated with G. mosseae and later supplemented with EDTA could be an effective and potentially suitable practice for the remediation of Cd-contaminated sites.
