The biofilms were investigated on surfaces of artificial substrata (glass microscope slides) submerged into the River Danube at the NE part of Szentendre Island. The collected biofilm samples were plated on two different diatom media. Diatoms were isolated and identified by scanning electron microscope from biofilm samples. Bacterial strains were isolated from surfaces of cultivated diatoms. The laboratory cultures and original gravel samples of the River Danube were similary examined by scanning electron microscope in order to determine the characteristic partner sin diatombacterial interactions. The studies have shown that bacteria with extracellular fibers attached to each pther and to the diatoms. Specific (molecular level) interactions between bacteria and diatoms were also investigated.
