Abstract:

Extracellular polymeric materials (ECP) and intracellular storage materials (glycogen and poly-β-hydroxybutyric acid) occur often in activated sludge mixed liquors. Factors known to affect biopolymer formation include: nutrient deficiencies, temperature changes, low active biomass content, and culture dynamics, but other stresses certainly can be expected to contribute. The study described in this paper shows how OUR fingerprints can be used to assess the amount of biopolymer present in activated sludge mixed liquor and provide insight into their potential impacts on treatment plant performance.
