Abstract: The paper is devoted to a study of the influence of the molecule structure of a number of o,o´- dihydroxyazo (DHA) compounds on their bactericidal ability toward sulfate-reducing bacteria (SRB) in the Postgate medium at small concentrations (5–20 mg/L). DHA compounds induce a decrease in number of bacterial cells, H2S production by SRB, and hydrogen permeation into carbon steel in the presence of SRB. The inhibition of steel corrosion in the bacterial medium by these substances is considered as well.

Keywords: carbon steel, microbiological corrosion, weight loss, hydrogen permeation, polarization, bactericide, inhibitor, structure, bacteria
