“…In contrast, Gabr et al 15 and Lopez et al 32 found the maximal pH for nickel biosorption for Pseudomonas aeruginosa ASU 6a and P. fluorescens 4F39 were 7.0 and 8.0, respectively. A decrease in the removal of Ni(II) at a pH above 6.0 is due to the formation of Ni(OH) 2 .…”

“…This complex process depends on the properties of metal ions, the cell wall composition of microorganisms, cell physiology, as well as physicochemical factors such as pH, temperature, contact time, ionic strength, and metal concentration 15 . It occurs through complexation, coordination, physical adsorption, chelation, ion exchange, inorganic precipitation or some combination of these processes 11, 16 .…”

“…This short time required for biosorption is in accordance with the results given by other authors 10, 15-17, 21, 30 . Gabr et al 15 , Joo et al 17 and Pahlavanzadeh et al 10 showed that the maximum biosorption of lead, zinc and nickel was reached after 30-40 min. A rapid metal sorption is also highly desirable for successful deployment of biosorbents for practical applications 16 .…”

The biosorption of Pb(II), Zn(II) and Ni(II) from industrial wastewater using Stenotrophomonas maltophilia and Bacillus subtilis was investigated under various experimental conditions regarding pH, metal concentration and contact time. The optimum pH values for the biosorption of the three metals were in the range 5.0-6.0, while the optimal contact time for the two bacterial species was 30 min. Experimental data was analyzed using Langmuir and Freundlich isotherms; the former had a better fi t for the biosorption of Pb(II), Zn(II) and Ni(II). The maximum adsorption uptakes (q max ) of the three metals calculated from the Langmuir biosorption equation for S. maltophilia were 133.3, 47.8 and 54.3 for Pb(II), Zn(II) and Ni(II), respectively, and for B. subtilis were 166.7, 49.7 and 57.8 mg/g, respectively. B. subtilis biomass was more favorable for the biosorption of Pb (II) and Ni (II), while S. maltophilia was more useful for the biosorption of Zn (II).

“…More than 90 % of bacterial strains obtained from Pb ore in this study could tolerate at least 100 ppm Pb. There are a wide range of Pb tolerances in scientific reports: Pseudomonas aeruginosa ASU 6a (Gabr et al 2008) was able to survive under the maximum range of Pb concentration up to 500 ppm, Entrococcus faecum Pb12 tolerates 800 ppm Pb (Bhakta et al 2012), and Achromobacter species TL-3 isolated from activated sludge samples tolerates 1500 ppm Pb in Luria broth medium (Batta et al 2013). The novel strain AS2 which was isolated from Pb ore in this study showed the maximum MIC to be higher than previous report and could survive up to 3125 ppm Pb.…”

A total of 422 bacterial isolates were obtained from the lead (Pb) ore in north-eastern Iran. The Pb tolerances of these strains were studied using microbroth serial dilution approach and 35 strains could grow up to 3250 ppm Pb concentration. Of these strains, 10 of them represented qualitatively high levels of Pb adsorption and were selected for quantitative studies. Strain AS2 which is phylogenetically related to genus Bacillus showed the highest level of Pb remediation. The effects of different factors, including pH, initial Pb concentration, temperature and inoculum size, were studied on the remediation process. Pb remediation capacity was reached at 74.5 mg/g (99.5 % of initial Pb) at pH 4.5, temperature 30°C, inoculum size 1.0 % (v/v) and an initial Pb concentration of 500 ppm after 24 h. Pb desorption capacity of strain was 66 %. The novel isolate could remove 98 % of Pb from the contaminated industrial wastes after 24 h. Pb uptaking to the cell surface was proven using scanning electron microscopic micrograph and energy-dispersive X-ray spectroscopy analysis. Most Pb removal efficiency was observed in the active cell culture as compared to the inactive cell and extracellular polymeric substances. The novel strain represents a good candidate for removal of environmental anthropogenic Pb pollutions.

“…Moreover, metal can be readily recovered from the biomass by desorption if the value and amount of recovered metals are significant and if the biomass is plentiful, metal-bound biomass can be incinerated, thereby extracting further treatment. The biosorption process depends on the type of metal ions, the cell wall structure of microbial biomass, cells shape, as well as physicochemical factors such as pH, temperature, contact time, ionic strength, and metal concentration (Gabr et al, 2008 andWierzba, 2015).…”
