Reporter strain activation with samples from polluted soil from a chromite processing facility. In A the reporter strain activation was assessed with different concentrations of the leachate soil. The table indicates the concentration applied to the plate. In B the reporter strain was exposed to samples of soil directly placed on top of the soft agar-cell mat surface and fixed with soft LB-agar. As a control, soil from a growing plant was used. The clear area on each experiment indicates cell death. The purple halos indicate reporter strain activation
