“…In the present study, E. coli P4 showed 56 % removal of Cd +2 from the aqueous medium. Bacteria may either bind Cd +2 to their cell surface or accumulate within their cells to reduce environmental Cd +2 pollution (Kuroda and Ueda 2003;Zouboulis et al 2004;Vargas-García et al 2012;Huang et al 2013).…”

“…Bioremediation of metal ions by using microbial biomass of bacteria (Vijayaraghavan and Yun 2008), algae (Feng and Aldrich 2004) and fungi (Yan and Viraraghavan 2003) is one of the most popular strategies due to environmental friendliness, cost effectiveness, and ability to work in low concentrations of metal ions (He et al 2011;Huang et al 2014). Some investigations have shown that bacterial strains, either dead or living form, have ability to accumulate cadmium ions (El-Helow et al 2000;Zouboulis et al 2004;Huang et al 2013). This bioaccumulation arises from metabolism independent extracellular adsorption by surface complexation, ion exchange or electrostatic interaction, and from metabolism dependent uptake leading to intracellular accumulation (Gadd 1990; Kuroda and Ueda 2003;Vargas-García et al 2012).…”

A cadmium-resistant bacterium was isolated from industrial wastewater and identified as Escherichia coli (dubbed as P4) on the basis of morphological, biochemical tests and 16S rRNA ribotyping. It showed optimum growth at 30 °C and pH 7. E. coli P4 found to resist Cd(+2) (10.6 mM) as well as Zn(+2) (4.4 mM), Pb(+2) (17 mM), Cu(+2) (3.5 mM), Cr(+6) (4.4 mM), As(+2) (10.6 mM), and Hg(+2) (0.53 mM). It could remove 18.8, 37, and 56 % Cd(+2) from aqueous medium after 48, 96, and 144 h, respectively. Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and Energy-dispersive X-ray (EDX) analysis also confirmed the biosorption of Cd(+2) by E. coli P4. However, temperature and pH were found to be the most critical factors in biosorption of Cd(+2) by E. coli P4. Cd(+2) stress altered E. coli P4 cell physiology analyzed by measuring glutathione (GSH) and non-protein thiol (cysteine) levels which were increased up to 130 and 48 %, respectively. Quantitative real-time polymerase chain reaction (qRT-PCR) showed alteration in the expression levels of ftsZ, mutS, clpB, ef-tu, and dnaK genes in the presence of Cd(+2). Total protein profiles of E. coli P4 in the absence and presence of Cd(+2) were compared by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), which showed remarkable difference in the banding pattern. czcB gene, a component of czcCBA operon, was amplified from genomic DNA which suggested the chromosomal-borne Cd(+2) resistance in E. coli P4. Furthermore, it harbors smtAB gene which plays a significant role in Cd(+2) resistance.

“…and yeast have been exploited for heavy metal treatment by B.V.SORBEX Inc. Visa Tech Ltd. and US Bureau of Mines, respectively (Gabr et al 2008). Currently more and more bacterial biomaterials have been applied in heavy metal removal (Huang et al 2013). The functional groups (amino, hydroxyl, carboxyl and sulfate) of polysaccharides, proteins and lipids on their cell walls can act as binding sites to attract and combine metals (Ng et al 2009).…”

In this study, strain BAPb.1 was isolated from lead mining area and used as an adsorbent to remove lead(II) ions from aqueous solution. The physicochemical characteristics, heavy metal resistance and antibiotic sensitivity of strain BAPb.1 were investigated. Biosorption capacity was evaluated by batch biosorption experiments, and isothermal characteristics were discussed. Atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectrometry (FTIR) were conducted to explore the mechanism for lead(II) adsorption. Based on morphological and physiological characteristics as well as the phylogenetic analysis of 16S rDNA sequences, strain BAPb.1 was identified as a member of the genus Alcaligenes. It exhibited high resistances to multiple heavy metals such as lead(II), copper(II), zinc(II), nickel(II) and chromium(VI), and to antibiotics such as kanamycin, ampicillin, streptomycin, chloramphenicol, and tetracycline. The optimum conditions for maximum biosorption rate of 85.2% and maximum capacity of 56.8 mg g -1 were found at pH of 5, adsorbent dosage of 1.5 g L -1 (dry weight), initial lead(II) concentration of 100 mg L -1 , and contact time of 30 min at 30°C. Biosorption isotherms were well fitted with Langmuir isotherm model. Mechanism analysis reveals that the lead(II) ions may exchange with sodium and potassium ions, and the hydroxyl, carbonyl and phosphate groups on the cell surface can chelate the lead(II) ions, therefore, surface adsorption play significant role in the biosorption process.

“…The highest goodness of linear fitting was achieved by LPSO, followed by LPFO and IPD models (Table 1). It is usually revealed that LPSO was most appropriate to describe biosorption [29][30] and physicochemical adsorption [31] ), while the calculated Cd removal capacity accounted for 108% of the maximum experimental one, which is close to the actual experimental outcome, further indicating that the LPSO model best described the Cd adsorption by immobilized SRB.…”

IntroductionOwing to the rapid development of industry, the resulting huge amount of wastewater containing heavy metals has posed a serious challenge to environmental protection. Among heavy metals, cadmium (Cd) is one of the most hazardous materials affecting the environment [1]. As an element of multiple industrial purposes, Cd is widely used in modern industries such as nickel-cadmium batteries, pigments, alloys, phosphate fertilizers, pesticides, textile operations, metal plating, Pol. J. Environ. Stud. Vol. 27, No. 6 (2018), 2851-2859 AbstractImmobilized sulfate-reducing bacteria (SRB) in polyvinyl alcohol (PVA)-sodium alginate matrix were applied as biosorbents to remove cadmium (Cd) from aqueous solutions. Multiple characterization techniques including scanning electron microscope (SEM)-energy dispersive spectrometer (EDS), and Fourier transform infrared (FT-IR) spectra indicate that immobilized beads provided a suitable microenvironment for SRB. Performance tests show that Cd removal was highly affected by pH value and temperature, with optimum temperature at 35ºC and pH value of 8.0. A pseudo second-order model was applied to describe the adsorption kinetic. FT-IR and x-ray photoelectron spectroscopy (XPS) analyses imply that biosorption, sulfide, and hydroxide precipitation are the main mechanisms for removing Cd. The immobilized SRB beads have great potential for remediating Cd-containing wastewater.
