Research Abstract

We have found the two interesting phenomena; the excrement of Marphysa sanguinea collected immediately after the organism excreted on sediment contained considerable amounts of PAHs, and the PAHs concentration reduced to half in 2 h. The rapid PAHs reduction might be attributed to the microorganisms in the excrement. To verify the speculation, the microorganisms in the excrement were incubated in the lipid medium suspended with pyrene for about 2 months, and extraction and analyses of a metabolite of pyrene in the culture were performed. As a result, we revealed the presence of a substantial metabolite of pyrene.
