Highlight important aspects of microbiological protection of underground facilities. It is shown that an important environmental and technological problem is the protection of underground oil and gas pipelines from microbial corrosion by soil corrosion-hazardous microorganisms, including the crucial role played by sulfatvosstanovitelnye (SRB) and thione (TB) bacteria. The influence of the nature of the inhibitor and the hydrophobicity of the electrolyte composition of basic and modified mastics. The influence of heterotrophic bacteria isolated from the damaged asphalt blocks pipeline, the stability of modified bitumen-polymer sealant. The effect of nitrogen-containing corrosion inhibitors on the growth and enzyme activity of the bacteria and the sulfur cycle, the mechanism locks thiobacteria and gidrogenaznoi reaction korozionnoaktivnih SRB. The efficiency of the derivatives dioksodekagidroakridina the rate of microbial corrosion of steel under the ISF and thiobacteria. A comparative evaluation of the effectiveness of these inhibitors in industrial inhibitor. These inhibitors provide a high degree of protection from corrosion in the presence of SRB (90%), which indicates their antibacterial properties and offers the prospect of their use in industrial applications of anaerobic corrosion caused by SRB.
