Outline of Final Research Achievements

By conducting this research, it became clear that contamination-resistant organisms are not only resistant to organic pollution, but also have high resistance and resolution against harmful chemical substances. It was suggested that drug metabolizing enzymes are involved in their degradation mechanism. In a purification test using contaminated sediments in the natural environment, it became clear that the purification ability varies depending on the species and combination. Therefore, in order to carry out environmental remediation efficiently, it is important to use not only a single biological species adapted to the actual pollution situation of the environment, but a combination of pollution-resistant organisms.
