[Development of mono- and associative cultures of sulphate-reducing bacteria and formation of exopolymeric complex].
Differences were found in development of the monoculture of sulphate-reducing bacteria Desulfovibrio sp. Kyiv-10 and artificial associations of cultures of sulphate reducing bacteria with heterotrophic satellites under development in a form of biofilm or plankton. Correlation between exopolymers synthesis in the biofilm and steel corrosion velocity has been found. Glucose, galactose, mannose, xylose, rhibose and nonidentified carbohydrates were found in the composition of exopolymers synthesized by monoculture Desulfovibrio sp. Kyiv-10 under its development in a form of biofilm. The biofilm and plankton cells of associative cultures synthesized exopolysaccharide which included rhamnose, arabinose and fucose. Glucose content in biofilm EPM was considerably higher (41.0055.9%) than in EPM of plankton cells (24.7-32.8).
