Effect of arbuscular mycorrhizal fungi (Glomus spp.) on growth and arsenic uptake of vetiver grass (Chrysopogon zizanioides L.) from contaminated soil and water systems
Phytoremediation technology is emerging as a promising environment-friendly method for large-scale cleanup of arsenic (As) contaminated water and soil. In this study we investigated the effect of arbuscular mycorrhizal fungi (AMF Glomus spp.) on the growth of the vetiver grass (Chrysopogon zizanioides L.) and its As uptake from contaminated hydroponic and soil systems. An ameliorative effect of...
متن کاملPhytoremediation of soil contaminated by heavy oil with plants colonized by mycorrhizal fungi
The purpose of this study was to investigate the effect of phytoremediation on soils contaminated with heavy crude oil using plants infected by mycorrhizal fungi. Five plant species, Vetiveria zizanioides, Bidens pilosa, Chloris barbata, Eleusine indica, and Imperata cylindrica, infected with the species of mycorrhizal fungi Glomus mosseae, were selected for this study. The degradation of total...
متن کاملEvaluation of Mobility, Bioavailability and Toxicity of Pb and Cd in Contaminated Soil Using TCLP, BCR and Earthworms
The objective of the present study was to investigate the reduction of mobility, availability and toxicity found in soil contaminated with lead (Pb) and cadmium (Cd) from Santo Amaro Municipality, Bahia, Brazil using two combined methods, commonly tested separately according to the literature: metal mobilization with phosphates and phytoextraction. The strategy applied was the treatment with tw...
متن کاملThe Optimal Root Length for Vetiveria zizanioides When Transplanted to Cd Polluted Soil.
In order to facilitate transportation and accelerate growth, roots of Vetiveria zizanioides must be pruned before transplanting. The present research is aimed to investigate the best root length for vetiver grown in cadmium (Cd) polluted soil. The results indicated that 6 cm root-length plant (RLP) was the best candidate in phytoremediation of Cd-contaminated soil for its stronger tolerance and...
متن کاملThe possible role of hydroxylation in the detoxification of atrazine in mature vetiver (Chrysopogon zizanioides Nash) grown in hydroponics.
The resistance mechanism of vetiver (Chrysopogon zizanioides) to atrazine was investigated to evaluate its potential for phytoremediation of environment contaminated with the herbicide. Plants known to metabolise atrazine rely on hydroxylation mediated by benzoxazinones, conjugation catalyzed by glutathione-S-transferases and dealkylation probably mediated by cytochromes P450. All three possibi...
