Biofilms form at the interface of condensed matters by bacterial activities. They affect our daily lives as well as industrial processes in various ways. Solving biofilm problems need intensive investigations. For this purpose, we need biofilm reactors and also some proper evaluation processes. In our experiment, we invented a new type of biofilm reactor used in laboratories to form biofilms on materials' surfaces. This apparatus makes us possible to form biofilms by using environmental biota. Usually, for most biofilm laboratory biofilm reactors, single bacterial species are used. However, this apparatus uses unknown bacterial species. In this presentation, we will show the appearance of the apparatus, the principle, the unique characteristics compared with other conventional ones. Biofilms generally form, so that bacteria in oligotrophic environments would survive. Therefore, bacteria seeking nutrition must exist in the system. This apparatus always makes it possible for us to utilize bacteria having a high potential capability of biofilm formation since the system would always contain plural bacteria. Some of the bacteria in the system could form biofilms well. Some concrete results using some metallic, polymeric, and ceramics materials will be shown as examples.
