Contribution of Extracellular Polymeric Substances (EPS) to the Sludge Aggregation
Environmental Science & Technology, 2010The contribution of extracellular polymeric substances (EPS), including loosely bound EPS (LB-EPS) and tightly bound EPS (TB-EPS), to the aggregation of both aerobic and anaerobic sludge is explored using the extended DLVO theory. It is observed that the aggregation abilities of both sludge samples decrease with the extraction of LB-EPS and TB-EPS ...

Overview of microalgal extracellular polymeric substances (EPS) and their applications
Biotechnology Advances, 2016Microalgae have been studied as natural resources for a number of applications, most particularly food, animal feed, biofuels, pharmaceuticals, and nutraceuticals. In addition to the intracellular compounds of interest, microalgae can also excrete various extracellular polymeric substances (EPS) into their immediate living environment during their life

Extracellular Polymeric Substances (EPS) and Extracellular Enzymes in Aerobic Granules
Drying Technology, 2010This work highlighted the main cause of vacuole formation, which may contribute to the stability loss for stored granules, using extracellular polymeric substances (EPS) fractionation in conjunction with fluorescence staining approaches. The results showed that the stored granules had an integrated appearance after 30 days' storage.

Stratification of Extracellular Polymeric Substances (EPS) for Aggregated Anammox Microorganisms
Environmental Science & Technology, 2017Sludge aggregation and biofilm formation are the most effective approaches to solve the washout of anammox microorganisms. In this study, the structure and composition of EPS (extracellular polymeric substances) were investigated to elucidate the factors for the anammox aggregation property.

Microbial Extracellular Polymeric Substances (EPS) in Fresh Water Sediments
Microbial Ecology, 2009Microbially produced extracellular polymeric substances (EPS) have been linked with many important ecological functions in natural sediments; yet, most information has been derived from marine systems. The present paper is the first comprehensive study on EPS (i.e., carbohydrates and proteins) dynamics in riverine sediments addressing spatial (six ...

Influence of extracellular polymeric substances (EPS) on Cd adsorption by bacteria
Environmental Pollution, 2011The role of extracellular polymeric substances (EPS) in Cd adsorption by Bacillus subtilis and Pseudomonas putida was investigated using a combination of batch adsorption experiments, potentiometric titrations, Fourier transform infrared spectroscopy (FTIR). An increased adsorption capacity of Cd was observed for untreated bacteria relative to that for

Influence of Extracellular Polymeric Substances (EPS) on Deposition Kinetics of Bacteria
Environmental Science & Technology, 2009The significance of extracellular polymer substances (EPS) on cell deposition on silica surfaces was examined by direct comparison of the deposition kinetics of untreated "intact" bacteria versus those from the same strain but with EPS removal via cation exchange resin (CER) treatment using a quartz crystal microbalance with dissipation (QCM-D).

Comparison of Extracellular Polymeric Substance (EPS) in Nitrification and Nitritation Bioreactors
International Biodeterioration and Biodegradation, 2019Abstract The production and composition of extracellular polymeric substances (EPS) are important parameters of bioreactor performance. This study compared the characteristics of EPS of nitritation- and nitrification-dominant processes in an integrated fixed-film activated sludge reactor.

Enhanced aerobic granulation with extracellular polymeric substances (EPS)-free pellets
Bioresource Technology, 2009Extracellular polymeric substances (EPSs) were secreted by cells after they agglomerated into a compact aggregate. This study shows that the EPS initially embedded in seed sludge before granulation may sterically slow subsequent microbe-microbe contact, thereby delaying aerobic granulation.

Role of Extracellular Polymeric Substances (EPS) in Biofouling of Reverse Osmosis Membranes
Environmental Science & Technology, 2009This study elucidates the mechanisms by which extracellular polymeric substances (EPS) impact permeate water flux and salt rejection during biofouling of reverse osmosis (RO) membranes. RO fouling experiments were conducted with Pseudomonas aeruginosa PAO1, EPS extracted from PAO1 biofilms, and dead PAO1 cells fixed in formaldehyde.
