The aim of this master's thesis is to study the biosorption of heavy metals copper, lead and zinc on thermophilic bacteria of the genus Geobacillus – G. thermodenitrificans CCM 2566 and G. thermocatenulatus CCM 2809. Biosorption was carried out in a batch stirred system for each metal separately. The influence of pH, biomass concentration and initial metal concentration on sorption capacity of bacteria was investigated. For both bacteria the optimum biosorption pH values for copper, lead and zinc were 5; 4 and 5, respectively. Sorption capacity of both bacteria was higher at lower concentrations of biomass and increased with increasing initial metal concentration. The confrontation of sorption capacities showed that the bacterium G. thermocatenulatus has greater sorption potential than G. thermodenitrificans.
