Ionomic responses to increasing environmental copper: results from experimental evolution of the bacterium Serratia marcescens

Abstract Divalent cations such as copper (Cu) occur in trace amounts yet play critical roles in bacterial physiology. Despite its essentiality, Cu is toxic at elevated concentrations and is widely applied as a bactericide, requiring cells to balance uptake, sequestration and effl...
