Abstract
The capability of reduction of oxidized sulphur compounds (sulphates, sulphites and thiosulphates) by wild strains of sulphate reducing bact eria (SRB) Desulfovibrio desulfuricans DV-5/86 and Desulfotomaculum ni grificans DT-5/86 was estimated basing on dynamics of hydrogen sulphid e liberation. The effectiveness of these processes was correlated with the biocorrosion rate of metallic copper in artificial aqueous media containing above mentioned substrates. It was demonstrated that corros ive aggressiveness of used media with selected sulphur compounds and i nvestigated bacteria strains were the highest in the presence of S2O3( -2) ions and the lowest in the system containing SO4(-2) ions.
