Abstract:Biofilm formation can be significantly influenced by surface material. In order to find the factors which can correlate the relationship between surface characteristics and biofilm formation, and to design novel surface materials which can be used to control biofilm formation, it is important to study the evolution processes of biofilm forming on different surface materials. The dynamic processes of biofilm of pseudomonas fluorescens on 17 kinds of surface materials were investigated experimentally. The evolution curves of biofilm formation were obtained. In addition, the induction period and the biofilm thickness or biomass were found from these evolution curves. The results show that the induction period and biofilm mass on different surface materials are quite distinct. The surface free energy and the interfacial energy for 9 kinds of surface materials were measured and calculated to find the relation between the biofilm information and these parameters. The results indicate that, however, only the interfacial energy between solid surface material and biofilm has some relations with the biofilm mass while other surface material and the interfacial energy have no clear relations with the biofilm formation.
