Bacteria and phytoremediation: new uses for endophytic bacteria in plants

The use of plants and bacterial to clean up environmental pollutants has gained momentum in past years. A limitation to phytoremediation of solvents has been toxicity of the compounds to plants, and the uncertainty as to the fate of many of the compounds. In a recent study, engineered endophytes have been shown to increase plant tolerance to toluene, and to decrease the transpiration of toluene to the atmosphere. This type of work has the potential to increase the use of phytoremediation by decreasing toxicity and increasing degradation of toxins.
