Abstract: The present investigation reports the biosorption capacity of Zinc sequestering bacterium VMSDCM in batch studies. In this work, an isotherm model has been proposed for the data obtained at equilibrium conditions. The results indicated that the validations of Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherm models were not satisfactory to describe proficiently the sorption of the zinc ion on the surface of the bacterium cells. The proposed model was found suitable to interpret the sorption of zinc ion on the surface of bacterium cells at boundary conditions. The biochemical characterization of the bacterium cells showed that the isolated cells were rod-shaped with gram-negative type of cell wall structure. The experimental uptake capacity reported at the attainment of the equilibrium was 431.5 × 103 mg of per unit (grams) biomass. © 2013 Springer-Verlag Berlin Heidelberg.
