“…Different strains have different ability in bioindicators of arsenic pollution. Trichoderma strain FA-06 is able to sporulate well on the arsenate exposure as compared to control and other Trichoderma strains [84]. Some Trichoderma strains have showed a decrease in pH ranging from 12.03 to 18.05% and 24.08 to 34.24% in arsenic treatment (Figure 2 and 3).…”

Cr(VI) represents an environmental challenge in both soils and waters as it is soluble and bioavailable over a wide range of pH. In previous investigations, Portulaca oleracea (a plant local to the UAE) demonstrated particular ability for the phytoextraction of Cr(VI) from calcareous soils of the UAE. In this publication, the results of the evaluation of P. oleracea phytoextraction of Cr(VI) from UAE soil at higher concentrations are reported. P. oleracea was exposed to nine different concentrations of Cr(VI) in soil from 0 to 400 mg kg -1 . The uptake of Cr(VI) increased as its concentration in soil increased between 50 and 400 mg kg -1 , with the most efficient removal in the range from 150 to 200 mg kg -1 . The total chromium concentrations exceeded 4600 mg kg -1 in roots and 1400 mg kg -1 in stems, confirming the role of P. oleracea as an effective Cr(VI) accumulator. More than 95% of the accumulated Cr(VI) was reduced to the less toxic Cr(III) within the plant.

“…Moreover, the effect of exogenous organic matter is pH dependent, allowing an increase in metal availability in alkaline soils (Santibáñez et al, 2008;Fagnano et al, 2011) while this is reduced in low pH soils (Alvarenga et al, 2009;Fornes et al, 2009). Interesting results could also be achieved by modifying the microbe-plant association in rhizo-soil (Cao et al, 2008), since microbes play a key role in soil element cycling. Fungi are well known for their ability to detoxify PTE through passive and active uptake (Kapoor et al, 1999), valence transformation or precipitation (Zafar et al, 2007).…”

Assisted phytoextraction of heavy metals: compost and Trichoderma effects on giant reed (Arundo donax L.) uptake and soil N-cycle microflora

et al. 2013

Little information is available as to the real effectiveness of the phytoextraction remediation technique, since laboratory experiments are still the most common way in which this is measured. Given this, an experiment on a cadmium-polluted soil was carried out in open field conditions in Southern Italy with the aim of assessing the growth and the phytoextraction potential of giant reed (Arundo donax L). Compost fertilisation and Trichoderma harzianum A6 inoculations were used to verify the possibility of increasing the metal uptake of the crop. Biomass yield of giant reed in the first growth season (average 12.8 Mg ha -1 ) was not affected by the Cd concentration in the soil and this increased significantly with compost fertilisation (13.8 Mg ha -1 ). Both compost fertilisation and T. harzianum inoculation increased cadmium uptake and translocation in leaves. Nitrifying bacteria was shown to be a useful tool to biomonitor soil quality. These results proved the suitability of the giant reed for assisted-phytoremedation with the use of compost fertilisation and T. harzianum. IntroductionThe extent of soil pollution by potentially toxic elements (PTE) in industrialised areas is well documented (Glass, 1998;Black, 1999) and represents an important environmental concern due to their potential accumulation in the food chain. Human activities such as industrial plants, mining, road transport and the unwise application of sewage sludges, fertilisers and pesticides to agricultural soils are recognised to be the main sources of PTE pollution (do Nascimento et al., 2006;Lado et al., 2008). A large number of methods are available to remediate soils, such as soil washing with synthetic surfactants. However, these are extremely expensive, such that a large number of sites remain contaminated (Ensley, 2000). Moreover, ex situ soil reclamation techniques lead to a big reduction in soil fertility due to the soil disturbance and to the toxicity of synthetic surfactants. Soil washing with humic substances extracted from composted organic matter or from geochemical deposits represents a reliable alternative (Conte et al., 2005) and phytoextraction is a valuable complementary technique. It is low cost and environmentally safe (Wu et al., 2006) and is able to both remove heavy metal pollutants from the soil and to offer important economic and agronomic advantages (Mattina et al., 2003). It involves the utilisation of plants to remove heavy metals from soil and concentrate them in the biomass. For years now, metal hyperaccumulating plants such as Alyssum murale, Berkheya coddii, Brassica juncea and Thlaspi caerulescens have been considered the most suitable tool to decontaminate metal-polluted soils, but the low biomass growth and scarce ability to accumulate various different metals together (Krämer, 2005) have discouraged their inclusion in commercial phytoextraction protocols (do Nascimento et al., 2006). Consequently, the current trend is to use fast-growing high biomass crops that accumulate moderate levels of metals in ...
