Wusirika, a biological sciences professor at Michigan Technological University, began his research using several species of Pseudomonas bacteria from the sediments of Torch Lake. In the region’s copper-mining heyday, the lake was used as a dump for mine waste. “We found bacteria that are resistant to high levels of copper,” he said. “We thought we might be able to use them to help plants grow better on contaminated soils.”
