Abstract: The study deals with bacteriological and anti-corrosion features of three domestic bactericidal corrosion inhibitors (CI) in presence of sulphate-reducing bacteria in an oxygen-depleted and CO2-containing nutritent medium. Efficacy of compositions under study in both inhibiting bacterial growth in an environment and decreasing total corrosion rate in structural steel was measured experimentally. Particular attention in discussion of results was paid to applicability conditions of optical evaluation method for bactericidal features of additives.
