ABSTRACT
The substances which show biocide effect on the associations of sulphate-reducing and iron-reducing bacteria have been revealed for the first time in the line of hydrobromide's para-(4'-chlorbenzyl)pyridine derivatives. Kinetic descriptions of the growth of sulphate-reducing bacteria in the presence of the above substances have been studied and the constants of inhibition have been calculated. The types of inhibition of the growth of sulphate-reducing bacteria by the investigated substances have been determined. The relations of chemical structure with antimicrobial characteristics of the investigated substances have been discussed.

Qualitative stability of corrosion-dangerous microbial association, extracted from ferrosphere of corroding underground pipelines in different soils is shown. Prevailing of sulphate-reducing and iron-reducing bacteria is peculiar to the structure of formed corrosion-aggressive microbial cenosis. Development of association of iron-reducing bacteria in the presence of acting matter of pesticide Linuron and its derivatives is depressed. The association of sulphate-reducing bacteria is sensitive only to the derivate that contains triazolazepine cycle and tolyl.
