The metal binding capacity of the thermophilic bacteria Geobacillus thermodenitrificans isolated from Damodar river, India was assessed using synthetic metal solutions and industrial waste water. Biosorption preference of dead biomass of G. thermodenitrificans for the synthetic metal solutions was in the following order Fe(+3)>Cr(+3)>Co(+2)>Cu(+2)>Zn(+2)>Cd(+2)>Ag(+)>Pb(+2). It reduced the concentration of Fe(+3) (91.31%), Cr(+3) (80.80%), Co(+2) (79.71%), Cu(+2) (57.14%), Zn(+2) (55.14%), Cd(+2) (49.02%), Ag(+) (43.25%) and Pb(+2) (36.86%) at different optimum pH within 720 min. When this strain was applied in the industrial waste water biosorption preference was in the following order Fe(+3)>Cr(+3)>Cd(+2)>Pb(+2)>Cu(+2)>Co(+2)>Zn(+2)>Ag(+) and concentrations reduced up to 43.94% for Fe(+3), 39.2% for Cr(+3), 35.88% for Cd(+2), 18.22% for Pb(+2), 13.03% for Cu(+2), 11.43% for Co(+2), 9.02% for Zn(+2) and 7.65% for Ag(+) within 120 min.
从印度达莫达尔河分离出的嗜热细菌 Geobacillus thermodenitrificans 的金属结合能力，使用合成金属溶液和工业废水进行了评估。死生物质的 G. thermodenitrificans 对合成金属溶液的生物吸附偏好顺序为 Fe(+3)>Cr(+3)>Co(+2)>Cu(+2)>Zn(+2)>Cd(+2)>Ag(+)>Pb(+2)。它在不同的最佳 pH 值内，在 720 分钟内将 Fe(+3)（91.31%）、Cr(+3)（80.80%）、Co(+2)（79.71%）、Cu(+2)（57.14%）、Zn(+2)（55.14%）、Cd(+2)（49.02%）、Ag(+)（43.25%）和 Pb(+2)（36.86%）的浓度降低到不同的水平。当这种菌株应用于工业废水的生物吸附时，其偏好顺序为 Fe(+3)>Cr(+3)>Cd(+2)>Pb(+2)>Cu(+2)>Co(+2)>Zn(+2)>Ag(+)，并在 120 分钟内将 Fe(+3)的浓度降低到 43.94%、Cr(+3)的浓度降低到 39.2%、Cd(+2)的浓度降低到 35.88%、Pb(+2)的浓度降低到 18.22%、Cu(+2)的浓度降低到 13.03%、Co(+2)的浓度降低到 11.43%、Zn(+2)的浓度降低到 9.02%和 Ag(+)的浓度降低到 7.65%。
