| Outline of Final Research Achievements |
The chlorinated organophosphorus compounds tris(2-chloroethyl) phosphate (TCEP) and tris(1,3-dichloro-2-propyl)phosphate (TDCPP) are persistent and widespread contaminants in various environments. Many studies have shown several toxic effects of the compounds. We have isolated novel bacteria degrading trihaloalkyl phosphates, Sphingobium sp. strain TCM1 and Sphingomonas sp. strain TDK1.
In this study, we analyzed the degradation systems of persistent chlorinated organophosphorus triesters in the triesters-degrading bacteria, the strain TCM1.

| Academic Significance and Societal Importance of the Research Achievements |
我々が世界で初めて単離に成功した含塩素有機リン酸トリエステル類分解菌 Sphingobium sp. TCM1 株に存在する分解システムとその調節機構を詳細に解析することは、学術的な貢献度が極めて高く、かつ独創的な点である。
また、得られた知見は、当該化合物を含む廃水の処理や汚染水域の環境保全・修復など、世界に先駆けた環境技術開発の基礎となるものであり、社会的な意義や貢献度も極めて大きい。
