Biocorrosion of natural and synthetic materials is an irreversible biochemical process, where a significant participation of bacteria societies takes place. The biocorrosion of concrete sewer pipes is caused mainly by the sulphuric bacteria and sulphate-reducing bacteria (SRB) forming a part of the biological circulation of sulphur and its compounds in biosphere. The aim of this work was to simulate a biocorrosion and to study the effect of simultaneous action of Acidithiobacillus thiooxidans ( A.t. ) and sulfate-reducing bacteria on concrete samples under model conditions. The biocorrosion effect has been proved and a further study is planed.
