The capability of reduction of oxidized sulphur compounds (sulphates, sulphites and thiosulphates) by wild strains of sulphate reducing bacteria (SRB) Desulfovibrio desulfuricans DV-5/86 and Desulfotomaculum nigriflcans DT-5/86 was estimated basing on dynamics of hydrogen sulphide 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 corrosive aggressiveness of used media with selected sulphur compounds and investigated bacteria strains were the highest in the presence of S2O3-2 ions and the lowest in the system containing SO4-2 ions.

The course of thiosulphate oxidation by selected strains of autotrophic bacteria Thiobacillus thiooxidans and Thiobacillus ferrooxidans as well as mixotrophic bacteria Sulfobacillus sp. and Siderocapsa sp. was analysed. Hexathionate and trithionate were found to be main intermediate compounds in iron-free solutions containing T. ferrooxidans, Sulfobacillus sp. or Siderocapsa sp., whereas tetrathionate was found in systems with T. thiooxidans. Tetrathionates were commonly present in iron-containing solutions inoculated with all tested strains. Chemical and biochemical processes, occurring within tested solutions, are discussed. Ferrous ion concentration > 0.02 g/dm3 was found to have inhibiting effect on the rate of biotic oxidation of thiosulphate.
