Article Synopsis
- Engineers have developed genetically modified bacteria (Bacillus subtilis) that can detect TNT in soil, focusing on how they perform over time compared to natural microbes.
- These engineered microbes are equipped with sensors and memory circuits, allowing them to respond to low concentrations of TNT and maintain that response for over 21 days.
- The study shows that these microbial sensors not only detect TNT effectively but can also coexist with other microbes, providing an added layer of safety for environmental monitoring.
We have conducted experiments to evaluate the effectiveness of removing contaminated soils from the Nevada Test Site with a large truck-mounted vacuum cleaner. Our results show that this method is effective, relatively easy, and safe for equipment operators. With four passes of the truck-mounted vacuum, 92% of the 241Am (and the accompanying 239 + 240Pu) was removed and resuspension rates were reduced by more than 99%.
