The Response of <em>Cupriavidus Metallidurans</em> CH34 to Cadmium Involves a Decrease in Intracellular Levels of C-Di-GMP Probably Mediated by a Novel Metal Regulated Phosphodiesterase That Inhibits the Biofilm Lifestyle
Abstract:Cadmium is a highly toxic heavy metal for biological systems. Cupriavidus metallidurans CH34 is a model strain for heavy metal resistance and bioremediation. The aim of this study was to determine the role of the c-di-GMP pathway in the C. metallidurans CH34 response to cadmium in both planktonic and biofilm cells. Increasing cadmium concentrations correlates with an inhibition of biofilm formation and EPS production in C. metallidurans cells. Planktonic and biofilm cells showed similar tolerance to cadmium.
