Sažetak
Studies of biofilm formation are essential for understanding and control of processes in natural aquatic systems and for industrial application. Experiments with expanding mercury electrode/seawater interface offer an approach to studies of initial monolayer in biofilm formation in seawater. Chronoamperometry of dissolved oxygen was used as a measuring technic. Dynamics of film formation is measured as a time which is necessary to reach a full coverage of the electrode by adsorption of dissolved biomolecules and/or adhesion of cells suspended in aqueous electrolyte solution. Phytoplankton organism D.tertiolecta, a free-living bacteria strain and hydrophobic Acinetobacter sp. were chosen as model organisms. Dextran and albumin were chosen as dissolved biomolecules, and triton T-X-100 as nonionic detergent. We have demonstrated direct competition of adsorption of dissolved biomolecules and adhesion of cells in the initial monolayer formation at a freshly exposed surface and a high rate of such processes.
