Modeling Microbial Chemistry

PIE scientists developed a novel approach to model how bacteria and other microscopic organisms transform organic compounds and nutrients in estuarine and other aquatic environments based on ideas from thermodynamics. The new approach will allow scientists to more accurately predict how estuaries and other ecosystems will respond to global change.
