| Abstract: | The effects of colloidal and soluble organic matters on the amounts and compositions of extracellular polymeric substances(EPS)in biofilms were studied in bench-scale biofilters.The results of experiments indicated that the amounts of carbohydrates and protein in biofilm EPS,as well as total EPS,were significantly influenced by the difference of substrate conditions.The surface properties of biofilms,observed by a scanning electron microscope,were to some extent affected by the substrate conditions. |
