Elucidation of biofilm formation and its control technology

本研究试图阐明生物膜的形成机理并发展生物膜的控制技术。结果发现，当微生物细胞粘附到固体表面时，生物膜形成的模式取决于相互作用自由能的变化。此外，明确了在使用磁场的流场中固定在生物膜容易形成的地方的磁性颗粒吸附降解酶可以抑制生物膜的形成。

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.
