The main focus of this study was to investigate the uptake of Zn and Cr by chromium-resistant bacteria, as well as the effects of varying concentrations of Si ions on these processes. The research objective Arthrobacter globiformis 151B was isolated from basalt samples collected from the area of Kazreti, Georgia, heavily contaminated with Cr(VI). The growth medium contained the research elements with the following concentration: Zn -1 μg/mL, Cr - 7 μg/mL. Bacteria were cultivated for 17, 24, 48, 96, and 144 hours. The concentration of Si ions in the growth medium made up 50, 200, and 800 μg/mL. After the cultivation of bacteria, the cells were sedimented by centrifugation. A bacterial pellet was prepared to measure concentrations of metals (zinc and chromium) using an atomic absorption spectrometer.
