Outline of Final Research Achievements

This study attempted to explore specific stimulants for 1,4-dioxane-degrading bacteria present in the environment, as a fundamental study for developing efficient bioremediation technology for 1,4-dioxane-contaminated groundwater. The results obtained in this study clarified that diethylene glycol is a specific growth substrate for known 1,4-dioxane-degrading bacterial strains, and that tetrahydrofuran can enrich 1,4-dioxane-degrading bacteria among diverse environmental bacteria and resultantly enhance the 1,4-dioxane-degrading ability.

Academic Significance and Societal Importance of the Research Achievements

各地で地下水汚染が顕在化しつつある1,4-ジオキサンに対する実用的な浄化技術の開発は喫緊の課題である。本研究では、効率的かつ低コストな新たな浄化技術になり得ると期待される分解菌を活用したバイオレメディエーションに着目し、1,4-ジオキサン分解菌の特異的増殖及び環境中からの集積に有望な炭素源を見出すことができた。本研究の成果は、1,4-ジオキサン分解菌の生物学的特性の理解深化や環境中における1,4-ジオキサン分解菌の合理的制御法の確立に資する基礎的知見であり、学術的にも社会的にも重要な意義を有している。
