| Research Abstract |
In this research, elucidation of biofilm formation and development of its control technology were attempted. As a result, it was found that the pattern of biofilm formation depended on the change of free energy of interaction when a microbial cell adheres to a solid surface. Moreover, it was clarified that the magnetic particle adsorbed degradative enzyme fixed on the place where the biofilm was formed easily in the flow field using the magnetic field preliminarily could inhibit the biofilm formation.
