Extraction of Extracellular Polymeric Substances (EPS) of Sludges
Journal of Biotechnology, 2002The efficacies of extracting extracellular polymeric substances (EPS) from aerobic, acidogenic and methanogenic sludges using EDTA, cation exchange resin and formaldehyde under various conditions were compared. Results show that formaldehye plus NaOH was most effective in extracting EPS for all sludges; only 1.1-1.2% of DNA in the sludge samples were ...

Staining of extracellular polymeric substances and cells in bioaggregates
Applied Microbiology and Biotechnology, 2007Multiple fluorochrome experiments with as many fluorochromes as possible are desired for exploring the detailed structure of bioaggregates. Spectral peak interference and other practical limitations, however, restrict the maximum number of stains used simultaneously to three.

Extracellular Polymeric Substances in Fouling Layer
Separation Science and Technology, 2006Abstract Membrane biofouling via microbial products limits the feasibility of utilizing membrane bioreactor (MBR) for treating wastewater. Fouling layer would be built up when activated sludge was filtered with a mixed cellulose ester membrane. This study probed the three‐dimensional distributions of protein, α‐polysaccharide, and β‐polysaccharide in ...

Extracellular Polymeric Substances of Bacteria and Their Potential Environmental Applications
Journal of Environmental Management, 2014Biopolymers are considered a potential alternative to conventional chemical polymers because of their ease of biodegradability, high efficiency, non-toxicity and non-secondary pollution. Recently, extracellular polymeric substances (EPS, biopolymers produced by the microorganisms) have been recognised by many researchers as a potential flocculent for ...

Extraction and application of extracellular polymeric substances from fungi
2023Extracellular polymeric substances (EPS) are extracellular metabolites of microorganisms, highly associated with microbial function, adaptation, and growth. The main compounds in EPS have been revealed to be proteins, polysaccharides, nucleic acids, humic substances, lipids, etc. EPS are not only biomass, but also a biogenic material.

Interaction of perfluorooctanoic acid with extracellular polymeric substances - Role of protein
Journal of Hazardous Materials, 2021Perfluorooctanoic acid (PFOA) is nonbiodegradable, and adsorption is the main pathway for its removal in wastewater treatment plants (WWTPs). This study compared the capability of three types of sludge on adsorbing PFOA and investigated the role of extracellular polymeric substances (EPS) in the adsorption process. Results show that enhanced biological

Microbial stabilization of riverine sediments by extracellular polymeric substances
Geobiology, 2007ABSTRACTSediment stability is a critical component for the understanding of cohesive sediment dynamics. Traditionally, physico‐chemical sediment conditions have been regarded as most important drivers of sediment stability. However, over the last decade, the stabilization of sediment by biological activity, particularly the influence of highly hydrated

Species of phosphorus in the extracellular polymeric substances of EBPR sludge
Bioresource Technology, 2013In this study, the species of extracellular phosphorus and their transformation during extracellular polymeric substances (EPS) extraction were explored by using (31)P nuclear magnetic resonance spectroscopy. Results show that the extraction methods had a substantial influence on the phosphorus species in the extracted EPS. Cation exchange resin method
