Bacteria to destroy dangerous toxins in groundwater
A trial by researchers has shown that the bacteria could be used to clean up polluted sites anywhere in the world. The trial involved cleaning up chlorinated solvents that leaked many years ago from a former Imperial Chemical Industries (ICI) chemical plant into the Botany Sands Aquifer in Australia, creating large plumes of contaminated groundwater.
Researchers collected bacteria occurring naturally in the Botany aquifer and isolated three bacterial communities that live off the breakdown of pollutants, including the first one known to degrade chloroform — a possible carcinogen that has been banned in consumer products.
“With present technology, it was expected that it might take decades or perhaps centuries before these toxic solvents are removed from the aquifer,” said associate professor Mike Manefield at the University of New South Wales, who led the research.
“Our tests showed that these bacteria effectively breathe these pollutants the way we breathe oxygen,” added Manefield, according to a New South Wales statement.
