Date issued/created: Subject and Keywords: Abstract:The ability of the following bacteria: Escherichia coli, Kliebsiella pneumoniae, Proteus mirabilis,Proteus vulgaris. Pseudomonas sp. to uptake cadmium from water solution was investigated.Based on the parameters of Freundlich and Langmuir equations it was found that the kind ofequation describing cadmium uptake by bacteria cells depended on the range of initial cadmiumconcentration in solution. Cadmium uptake by the investigated strains of bacteria from solutionwith low initial concentration of cadmium proceeded according to the Freundlich model. Increasing of the initial cadmium concentration above 30 mg Cd^"^ dm'^ resulted in a change of thecadmium uptake mechanism and sorption was according to the Langmuir model. The bestbiosorbents were Pseudomonas sp. and Proteus vulgaris which showed high sorption ability ina wide range of initial concentrations (1-200 mg Cd^^ dm'^). In the range of low initial cadmiumconcentration (1-30 mg Cd^"^ dm^), the most efficient biosorbent was Kliebsiella pneumoniae.
