| Abstract: |
| Organic pollutants present in soil may be taken up by plants and accumulated through food chain, thus threatening human health. There are amount of bacterial cells existed in rhizosphere soil, and many of them usually form biofilms on root surfaces, protecting plants from external harsh environments or promoting plant growth. Organic contaminants always need to pass through the biofilm on root surfaces before taken up by plant. In this paper, the formation of bacterial biofilm associated with roots were elucidated. The impacts of functional biofilm on the behavior of contaminants in rhizosphere were elucidated, and the mechanisms involved were clarified. Finally, we proposed a biofilm-mediated technique to eliminate plant organic contamination in polluted soils, hence benefiting agriculture production, food safety, and human and ecological health in contaminated sites. |
