Influence of corrosion inhibitor on extracellular polymeric substancesby sulfate-reducing bacteria

摘要

It was established, that the plankton cells of sulfate-reducing bacteria produced morernextracellular polymeric substances (EPS) than the biofilm cells, which was formed onrnsteel. In presence of inhibitor the amount of adhesion cells of sulfate-reducing bacteriarnon steel was reduced. It was shown, that inhibitor blocked synthesis of EPS in biofilm,rnwhich was formed by sulfate-reducing bacteria on steel surfaces and on contrary inrnplankton production of EPS was stimulated.
