The composition of exopolymer complexes (EPCs), synthesized by the monocultures Desulfovibrio sp. 10, Bacillus subtilis 36, and Pseudomonas aeruginosa 27 and by microbial associations involved in the corrosion of metal surfaces has been studied. An analysis of the monosaccharide composition of carbohydrate components, as well as the fatty acid composition(More)
The carbohydrate components of biofilms of corrosion-aggressive bacteria were studied by transmisstion electron microscopy using lectins labeled with colloidal gold. N-acetyl-D-glucosamine, N-acetyl-D-galactosamine, and neutral carbohydrates D-glucose and D-mannose were found within the exopolymeric matrix. Lectins with equal carbohydrate specificity(More)
It was shown that sulfate-reducing bacteria developed on the sections of Kyiv municipal heating systems, which are exploited in conditions of different temperatures. The bacteria were different as to their morphological and physiological properties. The bacteria of Desulfovibrio genus were revealed on the sections, which were exploited at a temperature of(More)
Experimental corroboration of correctness of theoretical thermodynamic calculations of e.m.f. of corrosion reactions induced by soil microorganisms is obtained in the work. A hypothesis is put forward on possible mechanism for stimulation of microbe-induced corrosion by chloride ions. The results obtained permit revealing the reasons of low efficiency(More)
