| Outline of Final Research Achievements |
This study was investigated the contamination status of Morganella psychrotolerans in detail seafood product in Japan, and the characterization and utilization of a newly isolated bacteriophage, MPV5, for preventing the growth and histamine accumulation. M.psychrotolerans was widely distributed in retail seafood product. An effective bacteriophage, MPV5, was successfully isolated from river water in this study. The viable count and histamine accumulation of M.psychrotolerans inhibited in broth and tuna meat by the phage MPV5 treatment. The combined treatment of MPV5 and sodium acetate enhanced to prevent the growth and histamine accumulation in tuna meat. These results suggest that phage treatment with MPV5 could be an effective biocontrol method to prevent the histamine poisoning by M.psychrotolerans in seafood.
