摘要: Different forms of microbial aggregates such as biofilms and flocs in natural engineered environments have common that the constituent cells these structures are embedded a hydrated matrix extracellular polymeric substances (EPS). These EPS supposed to consist predominantly polysaccharides proteins, but other macromolecules nucleic acids, (phospho)lipids, humic also been found varying amounts components wastewater activated sludges (Urbain et al. 1993; Jahn Nielsen 1996; Gehrke Sand, this volume).
