Outline of Final Research Achievements

The aim of this study is isolation of enzymes for persistent organic compounds, from the excrement of annelids, and their application to bioremediation. Some microorganisms which can degrade polycyclic aromatic hydrocarbons (PAHs), such as pyrene, were isolated from the excrement of an annelid, Iwamushi. As a result of in vitro degradation of pyrene by these isolates, a metabolite of pyrene, 1-hydroxypyrene, was detected from the medium, which was indicative of pyrene degradation. Moreover, although these microorganisms were added to the sediment containing high-concentration of PAHs, degradation of PAHs was not observed in several hours. Further works will be required for the application to bioremediation with these microorganisms isolated from the excrement of an annelid, in this study.
