Researchers are studying some common soil bacteria that “inhale” toxic metals and “exhale” them in a non-toxic form.
The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago.
Using a unique combination of microscopes, researchers at Ohio State University and their colleagues were able to glimpse how the Shewanella oneidensis bacterium breaks down metal to chemically extract oxygen.
I get a kick out of stories that I can send to two of my StumblePals. In this case, professional chemistry set-ter Frannyy and brownlands neighbour/guerrilla gardener Rodney. Enjoy!
