The interaction of Escherickia coli and Clostridium lituseburense with Cr(VI) and Cr(III) compounds is studied under anaerobic conditions. On the base of the thermodynamic prognosis and experiment, the bacterial reduction of Cr(VI) only to Cr(III) has been proved. A further reduction of Cr(III) to Cr(II) and Cr(0) is impossible because of the thermodynamic interdiction. Toxicity of chromium compounds is determined by their red-ox status. Reduction of Cr(VI) might be dependent on the acceptation of <$E roman H sub 2> from the terminal carriers. However, Cr(VI) is not used by strains in energetic metabolism as a terminal acceptor. Reduction of Cr(VI) by not adapted strains assumes the utilization of microbiological wastes (slits from aerotanks and methanetanks) for the purification of chromium-containing wastes.
