Extracellular Polymeric Substances (EPS) and Extracellular Enzymes in Aerobic Granules

Drying Technology, 2010
This 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.

Influence of extracellular polymeric substances (EPS) on Cd adsorption by bacteria

Environmental Pollution, 2011
The 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, 2009
The 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, 2019
Abstract 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, 2009
Extracellular 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, 2009
This 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.

Interactions between tannins allelochemicals and extracellular polymeric substance (EPS) of Microcystis aeruginosa

Environmental Science and Pollution Research, 2022
The protective mechanism of extracellular polymeric substance (EPS) secreted by a harmful cyanobacteria against tannins allelochemicals was explored in this study. The binding properties of soluble EPS (SEPS) and bound EPS (BEPS) of Microcystis aeruginosa to tannic acid (TA) were investigated via fluorescence spectroscopy. The results suggested that TA

Extracellular Polymeric Substance (EPS)

2015
Extracellular polymeric substances or EPSs are biosynthetic polymers from prokaryotic (bacteria, archaea) and eukaryotic (algae, fungi) microorganisms, which either form (loose or tight) slimes around the microbial cells or are excreted as discrete gels to the surrounding environment.

Effect of extracellular polymeric substances (EPS) on the attachment of activated sludge

Bioprocess Engineering, 2000
Extracellular polymeric substances (EPS) were removed by mechanical (high-speed centrifugation) and chemical (EDTA treatment) methods. The number of attached microorganisms decreased from 33.0 × 107 CFU/cm2 to 17.5 × 107 CFU/cm2 and 12.5 × 107 CFU/cm2, respectively.

Adsorption properties of chromium (VI) on extracellular polymeric substances (EPS)

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
The extraction of extracellular polymeric substances (EPS) from activated sludge and the absorption properties of chromium (VI) (Cr6+) on EPS were examined in this experiment. The effects of adsorption time, pH, mass of EPS, and initial Cr6+ concentration on Cr6+ removal efficiency were investigated. The results indicated that high speed centrifugation
