| Outline of Final Research Achievements |
When the Salmonella is cultured in DHL medium , the center of the colony alone shows black color. When it was smeared on the whole surface, it did not show black color, but when it was cultured with sliced lemon, a black ring, named Midoring showing hydrogen sulfide production activity around the lemon, was recognized. This was named MY phenomenon 1. We further discovered that when inoculate Salmonella by making it anaerobic, the visualization of hydrogen sulfide production becomes prominent. In this case, when adding antimicrobial substance to the center, a halo in that part apeared. A new antimicrobial test method was inovated. Salmonella hydrogen sulfide production was proved to be an indication of activation of bacterial growth. Furthermore, MY phenomenon 1 was found to be promoted also by the co-existence of Escherichia coli.
