 | | The bacterium, coccoid Strain 195, perfectly reduces the toxic pollutants tetrachloroethene and trichloroethene (also known as PCE, or perc, and TCE, respectively) to nontoxic ethene gas, the Cornell researchers report in the June 6 issue of Science. |
 | | For one thing, 195 is difficult to grow by itself; it seems to need chemical collaboration with other bacteria, and the pollution cleanup process may benefit from a little enhancement with extra hydrogen, nitrogen, phosphorous or even vitamins. |
 | | However, Strain 195 and other microorganisms may already be hard at work at some pollution sites, a possibility that the Cornell team can investigate, now that they know what to look for. |
