It is well recognized that biofilms can biosorb and biotransform heavy metals in aquatic environments. However, the effects of extracellular polymeric substance (EPS) on inorganic arsenic (As) bioaccumulation and biotransformation in biofilms are still unrevealed and need to be investigated.

What are Bacterial Extracellular Polymeric Substances?
1999The vast majority of microorganisms live and grow in aggregated forms such as biofilms and flocs (“planktonic biofilms”). This mode of existence is lumped in the somewhat inexact but generally accepted expression “biofilm”. The common feature of all these phenomena is that the microorganisms are embedded in a matrix of extracellular polymeric ...

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

The effects of extracellular polymeric substances on the formation and stability of biogranules
Applied Microbiology and Biotechnology, 2004Biogranulation is a promising biotechnology developed for wastewater treatment. Biogranules exhibit a matrix microbial structure, and intensive research has shown that extracellular polymeric substances (EPS) are a major component of the biogranule matrix material in both anaerobic and aerobic granules.

Extracellular Polymeric Substance (EPS)
2015Extracellular 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.

Molecular Insights into Extracellular Polymeric Substances in Activated Sludge
Environmental Science & Technology, 2020Extracellular polymeric substances (EPS) are known to crucially affect the properties and performance of activated sludge, but the detailed influential mechanisms and the pertinence to specific compositional, structural properties of EPS are still elusive.

Biodegradability of extracellular polymeric substances produced by aerobic granules
Applied Microbiology and Biotechnology, 2007This study investigated the biodegradability of extracellular polymeric substances (EPS) produced by aerobic granules. Aerobic granules were precultivated with synthetic wastewater in a lab-scale sequencing batch reactor. EPS were extracted from aerobic granules and were then fed as the sole carbon source to their own producers.

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 ...

Formation Processes of Extracellular Polymeric Substances
2012Extracellular polymeric substances (EPS) produced by mixed microbial community were characterized using gel-permeating chromatography (GPC) and three-dimensional excitation emission matrix (EEM) fluorescence spectroscopy measurement. The production of EPS, as well as its molecular weight (MW), depended on the external substrate utilization. A novel and

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.
