The article presents the results of studying the order of the chromate- and nitrate-reduction by denitrifying pseudomonades at the simultaneous presence of the chrome and nitrogen compounds in the cultural medium. The investigation of Cr (+6) recovery by bacteria of different taxonomic and physiological groups and oxidation reduction potential (ORP) shift in the process of chromate-reduction points to the fact that Cr (+6) recovers at higher ORP values than nitrate and it should be followed by the oxidized nitrogen compounds in the redox-order, not follow it as it was considered before.
