Conan the Bacterium with all it's positive aspects or potentially releasing a world destroying new superspecies.
WASHINGTON - Scientists are working to perfect a "superbug" that they think can help clean up toxic wastes at thousands of radioactive nuclear sites around the world.
The mighty microbe -- nicknamed "Conan the Bacterium" -- combines the genes of two bacteria to perform a job neither could do on its own.
The composite creature "can live quite happily in an environment with 1 million times the radiation a human cell could tolerate," Energy Secretary Spencer Abraham said this month.
Conan works because the radiation-resistant bacterium (Deinococcus radiodurans) shelters the microbe from lethal rays, while its partner (Pseudomonas putida) uses its native ability to render poisons in soil or water harmless.
For example, Conan can break down the chemical structure of toluene -- an ingredient in explosives such as TNT -- and leave only carbon dioxide and water.
"You can't get less toxic than that," Daly said.
Conan also works on mercury, dangerous pesticides such as chlorobenzene, and PCBs, which are carcinogenic compounds formerly used in manufacturing.
Although Conan's technology has been proved in the laboratory, field tests so far have been blocked by objections from environmentalists, who fear that genetic engineering may have harmful consequences.
