![]() ![]() We tested the crystals we made alongside commercially available products that are 99 per cent pure, and ours is either of identical or superior quality,” said James Hollibaugh, Professor, UGA Franklin College. “The antimony trioxide crystals produced by this bacterium are far superior to those that are currently produced using chemical methods. But the bacteria discovered by UGA researchers make antimony trioxide naturally as a consequence of respiration, creating a useful industrial product without creating noxious byproducts or requiring legions of specialized equipment. Traditional chemical methods used to convert antimony ore into antimony trioxide can be expensive, time-consuming and they often create harmful byproducts. ![]() To make these products, antimony must be converted into antimony trioxide, and this bacterium is capable of producing two very pure kinds of crystalline antimony trioxide perfectly suited for industry. It is particularly fond of arsenic, but it uses other related elements as well, and we think it may be possible to harness these natural abilities to make useful products out of different elements,” said Chris Abin, author of a paper.Īntimony, for example, is a naturally occurring silver-colored metal that is widely used by numerous industries to make plastics, vulcanized rubber, flame retardants and a host of electronic components including solar cells and LEDs. “Just like humans breathe oxygen, these bacteria respire poisonous elements to survive. The bacteria use elements that are notoriously poisonous to humans, such as antimony and arsenic, in place of oxygen, an ability that lets them survive buried in the mud of a hot spring in this unique saline soda basin. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in California, and their experiments with this unusual organism show that it may one day become a useful tool for industry and environmental protection. ![]() James Hollibaugh is a Distinguished Research Professor of Marine Sciences in the Franklin College of Arts and Sciences.ĪTHENS, GREECE: Colonies of bacteria buried deep in the mud along the banks of a remote salt lake near Yosemite National Park, California, US are found to have unusual property: they breathe a toxic metal to survive. ![]()
