“…For example, in module I, the genus Acinetobacter (Figure 3(b)), which is dominant in GGW, can be used to monitor the toxicity of heavy metals in wastewater (Abd et al 2006), while the genus Bifidobacterium can ingest iron under certain conditions (Kot and Bezkorovainy 1993). In module III, the dominant genera at ZMW, genus Brevundimonas and genus Chryseobacterium, have certain resistance to the bioaccumulation capacity of the heavy metals Pb, Hg, and Zn (Benmalek et al 2014;Hamzah et al 2015). Their dominance in module I and module III showed that heavy metal ions (Table S2) in wastewater from iron and steel plants and lighting plants are the key factors driving these bacteria.…”

Although the health of rivers is threatened by multiple anthropogenic stressors with increasing frequency, the impacts of different types of industrial pollution with regard to the structure and diversity of the bacterial community in the river have not been fully recorded. In order to study the composition and interaction of bacterial communities and co-occurrence patterns of bacterial communities in rivers polluted by different industries, we sampled the sewage outfalls of textile factory, food manufacturer, steel plant and lighting factory. The result showed that the bacterial community composition significantly differed in the rivers polluted by distinct types of industrial pollution. In addition, correlation-based network analysis showed that the microbial under different industrial pollution types have a nonrandom modular structure, and the nodes in the different modules perform different functions. In summary, adaptive changes in the composition of bacterial communities in rivers and the occurrence of species interactions are responses to different types of industrial pollution.

“…Bioaccumulation factor is an efficient tool to determine phytoremediation ability of plants in contaminated soil (Rezvani et al 2015). The BAF occurs when heavy metal absorbs and accumulates in plant shoot (Hamzah et al 2015). In all the three plants, there was a BAF higher than one that shows plants may have potential to hyperaccumulate Cd.…”

Potential of Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. for phytoremediation of Cd-contaminated soil

In three-pot experiments, the uptake and translocation potential of cadmium (Cd) by Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. was evaluated in different Cd concentrations including 0 (control), 5, 10, 15 and 20 mg Cd kg-1 dried soil. Plants accumulated Cd in their roots and shoots without toxicity symptoms. Enhancement of Cd concentration greatly decreased plant biomass. Bioconcentration factor (BCF) and translocation factor (TF) in F. subpinnata were higher than one that indicated higher efficiency of this plant for phytoextraction of Cd from soil. The efficiency of plants in uptake and translocation of Cd depends on species, biomass production, Cd concentration in biomass and soil. Cadmium concentration in M. aquatica root was higher than shoot. Mentha aquatica with higher BCF and lower TF than one can be suitable for phytostabilization of Cd. Also, uptake index and BCF for M. aquatica showed better phytoremediation potential in comparison with E. caucasicum and F. subpinnata.

“…Two heavy metal-resistant rhizobacteria, Brevundimonas diminuta SF-S1-5 and Alcaligenes faecalis SF-S1-60, applied individually, assisted Scirpus mucronatus growth in sand containing a mixture of 100 mg Pb kg −1 and 1 mg Hg kg −1 over 42 days. The presence of bacteria enhanced phytoaccumulation relative to the uninoculated plants, by up to 650 and 320 mg Pb kg −1 and up to 7.5 and 2.4 mg Hg kg −1 in roots and shoots respectively [ 144 ]. Growth and Hg 2+ uptake capacities were improved in Salvinia natans and Lemna minor grown in aqueous solution containing 0.3 mg Hg(NO 3 ) 2 L −1 , by the presence of three strains of epiphytic bacteria [ 145 ].…”

Mercury (Hg) pollution is a global threat to human and environmental health because of its toxicity, mobility and long-term persistence. Although costly engineering-based technologies can be used to treat heavily Hg-contaminated areas, they are not suitable for decontaminating agricultural or extensively-polluted soils. Emerging phyto- and bioremediation strategies for decontaminating Hg-polluted soils generally involve low investment, simple operation, and in situ application, and they are less destructive for the ecosystem. Current understanding of the uptake, translocation and sequestration of Hg in plants is reviewed to highlight new avenues for exploration in phytoremediation research, and different phytoremediation strategies (phytostabilization, phytoextraction and phytovolatilization) are discussed. Research aimed at identifying suitable plant species and associated-microorganisms for use in phytoremediation of Hg-contaminated soils is also surveyed. Investigation into the potential use of transgenic plants in Hg-phytoremediation is described. Recent research on exploiting the beneficial interactions between plants and microorganisms (bacteria and fungi) that are Hg-resistant and secrete plant growth promoting compounds is reviewed. We highlight areas where more research is required into the effective use of phytoremediation on Hg-contaminated sites, and conclude that the approaches it offers provide considerable potential for the future.
