Аннотация:The composition of microbial communities in coastal zones in the area of Kislogubskaya tidal power plant (the Barents Sea) and near Saint Petersburg Flood Prevention Facility Complex in the Gulf of Finland (Baltic Sea) was studied. The enrichment and pure cultures of microorganisms of various groups (sulfate-reducing, sulfur-oxidizing, nitrifying, ammonifying and iron-oxidizing bacteria) have been isolated, their cultural and physiological-biochemical properties, as well as their ability to induce corrosion of different materials used in the construction of hydraulic structures, have been studied.It should be noted that the constant presence of potentially corrosive groups of microorganisms in the sea water column and bottom sediments indicates the possibility of the formation of aggressive microbial communities in the form of biofouling and biofilms on hydraulic structures, which can significantly affect the operation of these structures and requires the development of protective measures against biofouling and biological damage.
