Bioremediation of selenium by plant volatilization
- Univ. of California, Berkeley, CA (United States)
Toxic levels of Selenium (Se) may arise in agriculture, e.g., from the irrigation of Se-rich soils, and in industry, e.g., Se-laden wastewaters from oil refineries and electric utilities. The cleanup of Se from soils and wastewaters can be achieved by using plants to absorb and remove Se. Once Se is taken up by plants, it can be converted into a non-toxic gas, e.g., dimethyl selenide, and removed completely from the ecosystem (phytovolatilization). We are conducting research into the use of phytovolatilization as a technique for the efficient and safe removal of Se from agricultural soils and industrial wastewaters (using constructed biochemistry, microbiology and molecular biology of phytovolatilization). Our future goals are to obtain the best plant/microbe associations for Se removal and transgenic plants which are super-volatilizers of Se.
