Metal Surface Modification to Moderate Marine Biofilm Formation And the Clarification of Moderation Mechanism

研究了不同金属在伊势湾海水环境中的生物膜形成行为。并通过一些基因分析，澄清了海洋中各种标本所形成的生物膜中细菌的种类。我们观察到生物膜中的大多数细菌是不可培养的，种类依赖于基质材料，并且由于形成的地质变化而发生微生物诱导腐蚀（MIC）。

Biofilm formation behaviors were clarified for various metals in marine environments, when they were immersed into Ise Bay. And by using some gene analyses, the species of bacteria in biofilm formed on various specimens in the sea were clarified. We observed that most bacteria in the biofilms were non-culturable, that the species depended on the substrate materials and also that the microbial induced corrosion(MIC) occurred due to the geological change by the formation.
