Engineer Receives $398,000 Grant to Study Nitrogen Cycle and Mussels

Wednesday, July 27, 2011

Anton Kruger, associate professor in the University of Iowa College of Engineering and associate research engineer at IIHR-Hydroscience and Engineering, has received a two-year, $398,000 grant from the Roy J. Carver Charitable Trust of Muscatine, Iowa, to fund research into an organism-based, biosensing network designed to test river nitrogen cycling on the Mississippi River.

The project involves studying nitrogen levels in the river by determining the health of mussels. Like the proverbial "canary in the coal mine," mussels could perhaps serve as an early warning system for pollutants and sediments in the Mississippi River. As they feed by filtering water, they transfer nutrients from water to the riverbed.

The project will be conducted, in part, at IIHR's Lucille A. Carver Mississippi Riverside Environmental Research Station, located near Muscatine and on the banks of the Mississippi River.

This grant from the Carver Trust was made through the UI Foundation, which is the preferred channel for private support for all areas of the university. To learn more, visit
