Exopolymeric substances (EPS) were extracted by EDTA from activated and anaerobic granular sludge. Due to the presence of EDTA in EPS extract, interferences were pointed out for the characterization of EPS by means of the colorimetric methods and fluorescence spectroscopy. Other methods have been investigated to characterize the EPS protein fraction. Size exclusion chromatography (SEC), performed at a fluorescence excitation-emission matrix of 221/360 nm (tryptophan protein-like substances) for… CONTINUE READING
