|概要||Recent organic pollution is caused by phosphorus-based anthropogenic eutrophication, which occasionally lead heavy metal pollution. In this presentation, causes of the recent organic pollution in ecological system are briefly introduced, and our approaches, based on studies of microbial biosensor methods as tools for estimating the degrees of the recent organic pollution and heavy metal pollution, are introduced.
As the microbial biosensor methods for the recent organic pollution, we have developed single or double mediator method, chemiluminescence method applying the principle of the double mediator method, and highly sensitive isothermal absorptiometric method. In the absorptiometric method, we have also developed a biosensor method for sea water using salt-tolerant yeast.
In the approaches of the microbial biosensor methods for heavy metal pollution, we have developed unique technique employing damped metabolic oscillation induced in living yeast cells. In addition, other environmental water biosensor methods for eutrophication, agriculture, and viable microbial assay are also introduced.
Finally, future perspectives of our microbial biosensor developments for environmental analysis relating to the organic pollution are discussed.
