Measurement of residual heavy metal in biosorption assay. Biosorption of mixed heavy metals were using a sequential removal strategy. The 100 ml of soil extract was inoculated with 1 OD600 of GYF-1 concentrate, and shaking at 30oC for 24 h. The culture was centrifuged, 5 ml of supernatant was sampled, and the rest was inoculated again with GYF-1 concentrate for another 24 h incubation at 30oC. The residual concentration of (A) Cd2+, (B) Cr6+, (C) Cu2+, (D) Ni2+, (E) Pb2+, (F) Zn2+, or Fe2+ left in all collected samples were determined by AAS (n = 3)
