Rape seed plants can clean up toxic soil with a bacterial injection, according to my colleague Doris De Guzman on Green Chemicals Blog.
The with suitable injections of bacteria, the plants grow faster and can help remove heavy metal residues such as lead and cadmium from contaminated land.
What is not clear from this is whether the heavy metals are captured by the bacteria or find their way into the seeds of the plants or whether it would be possible to separate them out safely. I don't think the world needs pre-leaded biofuels does it?
