Environmentally unfriendly and expensive chemicals
are one of the few methods for cleaning up pollution caused by mining
operations — like those in northern Minnesota — that can let harmful
substances into the earth.
But thanks to University of Minnesota student research, efforts to
undo mercury pollution in waters contaminated by mining might have a new
tool. A 24-person team of mostly undergraduates has developed tiny
beads filled with genetically engineered bacteria that can clean up
mercury and other poisonous heavy metals, said team leader and
microbiology senior Basem Al-Shayeb.
