Transgenic Poplar for Phytoremediation
January 11, 2008| |
Scientists from Purdue University are working with Chrysler LLC to test the efficiency of GM poplars in removing contaminants from soil and underground water. The transgenic poplar trees are developed by introducing the mammalian gene coding for a cytochrome (iron containing proteins). The transgenic lines were observed to have capabilities for removing and degrading pollutants like trichloroethylene (TCE), vinyl chloride and carbon tetrachloride from soil and ground water. Most of these compounds, known as carcinogens or neurotoxins, are widely used in industries and found their way into groundwater because of improper disposal. The GM poplar trees were also found to be capable of removing air pollutants like vinyl chloride, chloroform and benzene, substances usually used in petroleum and plastic processing. If approved by the Animal and Plant Health Inspection Service (APHIS), the trials will be performed in a former oil storage facility in Indiana.
