Prichodko S. Functioning of corrosive-active microbial community of soil in the presence of derivatives of triazolazepine.

The dissertation is devoted to the study of functioning of corrosive-active microbial community of soil and influence on it derivatives of triazolazepine. The sensitiveness of sulphate-reducing, iron-reducing and denitrifying bacteria to the row of new derivatives of triazolazepine is settled. The inhibition of noncompetitive type of growth of sulphate - reducing bacteria by derivatives of triazolazepine is set, which increases at the change of position of metylene deputy in benzol ring in a row: orto- < meta < para. Increase of anticorrosive action of derivatives with a metylene deputy in an aromatic ring under the conditions of biocorrosion of the steel, caused by sulphate-reducing bacteria, conforms with strengthening of their biociding activity. Taking into account intercommunication between the structure of molecules and inhibiting action of derivatives of triazolazepine, inhibitor of microbial corrosion of steel with biociding action - derivatives of urea is found, which is got on the basis of functioning matter of pesticide linuron and it displays protective effect 77,8%. Inhibitor with biociding action is derivatives of triazolazepine with protective effect 87,4% is recommended for warning of microbial corrosion of steel.
