Could microbes solve Russia's chemical weapons conundrum? One of nature's most versatile microorganisms - a bacterium called Pseudomonas putida - could help mop up the toxic by-products caused by the destruction of the chemical weapon mustard, write Russian researchers in Journal of Chemical Technology and Biotechnology this month. At 40,000 tonnes, Russia houses the world's largest stockpile of chemical warfare agents (CWAs). The country faces a race against time to dispose of the stockpile by 2007, in accordance with the Chemical Weapons Convention (CWC). This disposal must be achieved in an ecologically-sound manner.
