“…In addition, the calculated data to determine the absorption capacity of dead biomass indicated a significant difference mediated by the exposure time to the metal. This could be related to the available places where the metal joins and the interactions with the dead material [5] , which could even be variable, but independent of the strain used, as evidenced in this study.…”

“… [13] ) achieved a maximum removal of 85.38% of Pb +2 from an aqueous solution and a biosorption capacity of 123 mg/g of dead cells, using Aeromonas hydrophila MTCC 646 biomass [13] . Removal percentages between 90 and 95% have even been obtained with other metals like Al +3 using dead Pseudomonas putida A (ATCC 12633) biomass, determining a biosorption capacity of up to 0.55 mg/g of biomass [5] , which shows more efficiency. Some studies have also suggested that live cells are metabolically active and can produce H + ions, which could generate competence with metal ions, thus reducing the biosorption capacity of the toxic metal [ 5 , 11 ].…”

“…Among them, Pseudomonas and Ensifer which increased to more than 1% played key roles during phytoremediation by S. integra. Moreover, Pseudomonas strains have been developed as bioinoculants for phytoremediation, bioremediation of metals, and methylmercury degradation (Boeris et al, 2016;Cabral et al, 2016;Sun et al, 2017). Uncultured bacteria with higher abundance in all the treatments were promoted only by Pb contamination, but their functions cannot be ignored.…”

Indigenous Bacteria Have High Potential for Promoting Salix integra Thunb. Remediation of Lead-Contaminated Soil by Adjusting Soil Properties

Salix integra Thunb., a fast-growing woody plant species, has been used for phytoremediation in recent years. However, little knowledge is available regarding indigenous soil microbial communities associated with the S. integra phytoextraction process. In this study, we used an Illumina MiSeq platform to explore the indigenous microbial composition after planting S. integra at different lead (Pb) contamination levels: no Pb, low Pb treatment (Pb 500 mg kg −1 ), and high Pb treatment (Pb 1500 mg kg −1 ). At the same time, the soil properties and their relationship with the bacterial communities were analyzed. The results showed that Pb concentration was highest in the root reaching at 3159.92 ± 138.98 mg kg −1 under the high Pb treatment. Planting S. integra decreased the total Pb concentration by 84.61 and 29.24 mg kg −1 , and increased the acid-soluble Pb proportion by 1.0 and 0.75% in the rhizosphere and bulk soil under the low Pb treatment compared with unplanted soil, respectively. However, it occurred only in the rhizosphere soil under the high Pb treatment. The bacterial community structure and microbial metabolism were related to Pb contamination levels and planting of S. integra, while the bacterial diversity was only affected by Pb contamination levels. The dominant microbial species were similar, but their relative abundance shifted in different treatments. Most of the specific bacterial assemblages whose relative abundances were promoted by root activity and/or Pb contamination were suitable for use in plant-microbial combination remediation, especially many genera coming from Proteobacteria. Redundancy analysis (RDA) showed available nitrogen and pH having a significant effect on the bacteria relating to phytoremediation. The results indicated that indigenous bacteria have great potential in the application of combined S. integra-microbe remediation of lead-contaminated soil by adjusting soil properties.

“…They are non-degradable chemical species and have a strong tendency to bioaccumulate, which makes these metals potentially dangerous to living organisms. Aluminum is classified as a toxic metal and remarkable concentrations of this metal have been reported in effluents from several industries, e.g., mining, smelting, metallurgy and electroplating (Vijayaraghavan et al 2012;Boeris et al 2016). Another significant source of effluents contaminated by aluminum are water treatment plants, due to the use of chemicals composed of aluminum (aluminum sulfate and polyaluminium chloride) in the flocculation process, often high concentrations of the metal are found in effluents from this treatment step (Merian et al 2004;Stephens and Jolliff 2015).…”

The residue derived from the alginate extraction from S. filipendula was applied for the biosorption of aluminum from aqueous medium. The adsorptive capacity of the residue (RES) was completely evaluated in batch mode. The effect of pH, contact time, initial concentration and temperature was assessed through kinetic, equilibrium and thermodynamic studies. The biosorbent was characterized prior and post-Al biosorption by N2 physisorption, Hg porosimetry, He picnometry and thermogravimetry analyses.Equilibrium was achieved in 60 minutes. Kinetics obeys pseudo-second order model at aluminum higher concentrations. Isotherms followed Freundlich model at low temperature (293.15 K) and D-R or Langmuir model at higher temperatures (303 and 313 K). Data modeling indicated the occurrence of both chemical and physical interactions in the aluminum adsorption mechanism using RES. The maximum adsorption capacity obtained was of 1.431 mmol/g at 293 K. The biosorption showed a spontaneous, favorable and exotherm character. A simplified batch design was performed, indicating that the residue is a viable biosorbent, achieving high percentages of removal using low biomass dosage.
