The results of study of the derivatives of 1,4-hydroquinone as inhibitors ofmicrobiological corrosion and hydrogen absorption of mild steel in a water-saltmedia supporting the development of sulphate reducing bacteria (SRB) andclose by its composition to the sea water containing biogenic hydrogen sulphide.Content of H2S, bacterial titre in the corrosive meas well as its pH, Eh andpotential of steel '; were determined together with the quantity of hydrogenabsorbed by surface layers of steel. Protective efficiency of the best studiedspecies from corrosion reaches 65...84 %, as for their action against hydrogenabsorption by steel specimen 60...72 %. The decrease of the number of SRBcells due to the action of the derivatives of 1,4-hydroquinone was found to be48...84 %, while the suppression degree 29...57 % (at the concentration of5 mMol/L).Key words:
