| Outline of Final Research Achievements |
This study tested a hypothesis that a part of Escherichia coli in coastal area acquires resistance against salt (sodium chloride), and they cannot be detected using ordinary selection media”. A field survey at a coastal area in Japan found higher concentration of E. coli using selective agar supplemented with salt compared to the ordinary agar in summer season. But the salt-resistant E. coli strains isolated from the water samples showed low growth rates in salt-supplemented media, indicating that salt inhibits growth of salt-resistant E. coli strains. These finding implies that E. coli in coastal water shows lower overall decay rates due to the strains possessing salt-resistance.
