摘要：In present work, effect of two types of rhizobacteria was investigated on Scirpus mucronatus plant grown in contaminated soil spiked with 1 ppm Hg and 100 ppm Pb using phytoremediation technique. The concentrations of Hg and Pb in root and shoot of Scirpus mucronatus plant were determined on 1th, 7th, 14th, 28th and 42th days after enrichment by bacteria using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). To evaluate statistical differences in the Hg and Pb concentrations, the one-way ANOVA test was used. There were statistically significant differences between Hg and Pb concentrations between samples of control, bacteria 5 and bacteria 60. The results were demonstrated that these two bacterial inoculums namely Brevundimonas diminuta and Alcaligenes faecalis were known as plant-grown promoting rhizobacteria and they can increase the heavy metal uptake from soil contaminated.
