| Outline of Final Research Achievements |
Rhizoremediation is an environmentally-sound promising technology that utilizes aquatic plants and rhizobacteria to cleanup polluted environment. This study aimed to reveal a mechanism of accelerated degradation of aromatic compounds in the rhizosphere of duckweed. Using 4-tert-butylphenol (4tBP) as a model aromatic compound, bacterial community in the rhizosphere of 4tBP-degrading duckweed was analyzed. Bacterial community of duckweed rhizosphere, where bacteria belonging to family Pseudomonadaceae and Sphingomonadaceae were dominated, was significantly different from that of environmental water. Transcriptomic analysis of 4tBP-degrading Sphingobium fuliginis OMI, originally isolated from duckweed rhizosphere, revealed that pivalate degradation pathway is related to the 4tBP degradation.
