My project utilizes the important N-fixing bacteria Bradyrhizobium japonicum USDA110 as a putative indicator species to screen for potential soil fertility disruption in agricultural systems due to applied Cu(OH)2 engineered nanoparticulate biocides. My work will test anticipated in-field exposure concentrations, make predictive toxicological assessments, and consequently help inform decisions toward more sustainable agricultural management practices.
