title: [Microflora of damaged ferroconcrete structures under the conditions of inhibitory protection].
abstract: Thionic, sulphate-reducing, denitrifying and ammonifying bacteria widely distributed in the sewer system on various structure elements have been isolated from damaged ferroconcrete samples. Effect of protective materials on microbe-induced corrosion of metal famework of concrete samples has been studied. Selective effect of corrosion inhibitors and coatings on the growth of corrosion-active bacteria of sulphur and nitrogen cycle has been revealed. It is shown that acid medium formed by thionic bacteria is more aggressive than ammonium-hydrosulphide one formed by denitrifying and sulphate-reducing bacteria. It has been established that the corrosion inhibitor--pyrquin, organosilicon coating CO-FMI and epoxyorganosilicon coating 4sk are most effective materials as to the action of thionic bacteria--dangerous agents of ferroconcrete aerobic corrosion.
