Formation control of purple phototrophic bacteria bio-film by micro fabrication for environmental application

生物膜是细菌在固体表面增殖的膜状结构。该薄膜有望应用于燃料电池、促进光合作用等环境领域。本研究旨在利用固体表面微加工技术对紫色光养细菌生物膜的形成、控制及应用进行研究。研究了材料性能和表面微加工对紫色光养细菌培养的影响。利用直接光合作用型燃料电池，通过实验明确了细菌培养过程中生物膜形成状态与光合作用能力的关系。本研究考察了生物膜状态，使光合作用效率高。

Bio-film is the film structure of bacteria which proliferates on the solid surface. This film is expected to be able to apply to the fuel cell and the photosynthesis promotion, etc in the environmental field. In this study, it aimed to the formation control and the application of bio-films of the purple phototrophic bacteria by using the surface of the solid with micro fabrications. It is investigated that the material properties and the surface micro fabrication effect on the purple phototrophic bacteria culture. It was clarified experimentally the relationship between the state of the bio-film formation on the bacteria culture and the photosynthesis ability by using direct photosynthesis type fuel cell. This study examined the bio-film state to make the photosynthesis ability highly effective.
