| 研究実績の概要 |
The research went smoothly as planned. In this year, I focused on rhizosphere of arsenic hyperaccumulators Pteris vittata and Pteris multifida and role of rhizosphere bacteria to elucidate the interactions of plants and rhizobacteria. The aim of this study was to investigate the potential of rhizobacteria in enhancing the effect of arsenic phytoextraction. Seventy-eight strains rhizobacteria was isolated and identified by blasting to gene bank. Their traits were characterized to select the optimal isolate. The interactions of selected multifunctional strain with plants were exhibited positive effects. Further, co-cultivation of rhizobacterium and ferns achieved the promotion arsenic phytoremediation. I wrote two papers, one was published, another one was under reviewing. According to papers writing, I obtained a deeper understanding of research, which can lay a solid foundation for further research plan. And I attended an international conference and national conference. Academic communication provides the enlighten thoughts and ideas about my research.

理由
The title of my research is “Study on rhizosphere of arsenic hyperaccumulators forward to develop an efficient phytoremediation technology”. I mainly focused on rhizosphere of arsenic hyperaccumulators Pteris vittata and Pteris multifida and role of rhizosphere bacteria to elucidate the interactions of plants and rhizobacteria. The aim of this study was to investigate the potential of rhizobacteria in enhancing the effect of arsenic phytoextraction. And base on it, rhizobacteria was isolated and identified by blasting to gene bank. Their traits were characterized to select the optimal isolate. The interactions of selected multifunctional strain with plants were exhibited positive effects. Further, co-cultivation of rhizobacterium and ferns achieved the promotion arsenic phytoremediation. The research went smoothly as planned. Each experiment was conducted after a lot of relevant literatures investigating, independent thinking and communication with professor or laboratory members.
