Enzyme activities in activated sludge flocs [PDF]
Applied Microbiology and Biotechnology, 2007 This study quantified the activities of enzymes in extracellular polymeric substances (EPS) and in pellets. Seven commonly adopted extraction schemes were utilized to extract from aerobic flocs the contained EPS, which were further categorized into loosely bound (LB) and tightly bound (TB) fractions.
