Abstract:In this study, the Cu2+ (120 mg/L) and Cr6+(80 mg/L) removal rate of S. rhizophila JC1 reached at 79.9% and 89.3%, respectively. Scanning electron microscopy showed that Pb2+ and Zn2+ had no obvious effect on cell structure, but the cells became smaller and brighter under Cu2+ stress, and many nanoparticles formed on the cell surface under Cr6+ stress. The physiological response analyses demonstrated that moderate change of membrane permeability was necessary for adsorption. FI-IR and EDS analyses showed that … Show more
