Abstract

Some bacteria from Arthrobacter genera have great potential for bioremediation. Two strains of Arthrobacter, one isolated from Georgia, contaminated Kazreti region and second- from Columbia basalt rocks of the contaminated site of the US, exhibit resistance against high concentrations of Cr(VI) and other metallic ions. They can reduce highly toxic and carcinogenic Cr(VI) into Cr(III). We investigated the behavior of bacteria with following metals: K+, Cr(VI) and Mg(II), their uptake process by living, aerobic Arthrobacter oxydans and influence of K+ and Mg(II) on the uptake process of Cr(III) by Arthrobacter sp. 61B. Metal accumulation ability by bacteria, was analyzed using Atomic Absorption Spectroscopy.
