The basic investigations on symbiosis between aquatic plants and rhizobacteria were performedto evaluate the possibility of the low-carbon and environmentally-friendly water quality conservation system againstaromatic compounds contamination. The root exudate of Spirodela polyrrhiza, a duckweed, was revealed to be composed of several phenolic components, and the trace components of the root exudate were varied depending on the chemicals to which S. polyrrhiza was exposed. The accelerated degradation of various aromatic compounds were confirmed in the rhizosphere of Phragmites australis, a reed, as well as S. polyrrhiza. In addition, 4-tert-butylphenol(4-t-BP) degrading bacteria were isolated from their rhizosphere for the first time, and their 4-t-BP degradation pathway and mechanism of accelerated 4-t-BP degradation could be clarified.

通过水生植物与根际细菌共生关系的基础研究，探讨了构建低碳环保型水体保护系统的可行性。水萍多根螺旋藻根系分泌物中含有多种酚类物质，其微量组分因受S. polyrrhiza暴露。芦苇根际和芦苇根际对多种芳香族化合物的降解均有加速作用。多根此外，首次从4-t-BP的根际土壤中分离到4-t-BP降解菌，初步阐明了4-t-BP的降解途径和加速4-t-BP降解的机理。
