Outline of Final Research Achievements

To develop new type of safe disinfectants, we have systematically examined and characterized microbicidal activities of food-derived compounds, such as arginine, umezu-polyphenol, and so on. For examples, arginine showed very strong killing activity against pseudomonas aeruginosa and umezu-polyphenol showed marked virucidal activities against respiratory infectious viruses, such as influenza A and B viruses and human rhinoviruses, suggesting a potential use of arginine as a preventive medicine for the infection with these viruses. On the other hand, for good estimation of the practical efficacy of disinfectants, we quantitatively analyzed the life time of the viruses on the contaminated surface in various hospital settings.
