%X Molecular fluorescence technology and fluorescence titration methods were applied to elucidate the mechanism of association between the protein-like regions of two extracellular polymeric substances (EPS) and the heavy metal Cd. After combining the protein-like EPS with Cd, fluorescence spectra were used to further analyze the difference of configuration between the loosely bound extracellular (LB) and tightly bound extracellular polymeric substance (TB). An obvious quenching effect of LB triggered by Cd co...
