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)
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.

Effect of extracellular polymeric substances (EPS) on the attachment of activated sludge
Bioprocess Engineering, 2000Extracellular 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), 2011The 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

Applied Microbiology and Biotechnology, 2015
This paper reviews the formation, structure, and stability of bioaggregates with an emphasis on the composition and distribution of extracellular polymeric substances (EPS) and their role in bioaggregation. Bioaggregation is ubiquitous in natural environment and is of great importance in biological wastewater treatment processes.

The influence of an extracellular polymeric substance (EPS) on cohesive sediment stability
2002Extracellular polymeric substances (EPS) are secreted by a variety of benthic organisms including diatoms and bacteria. These substances are often considered the primary mechanism by which intertidal benthic organisms increase sediment stability. The stabilisation is caused by physico-chemical interactions between clay minerals and EPS and physical ...

[Biodegradability of extracellular polymeric substances (EPS) produced by aerobic granules].
Huan jing ke xue= Huanjing kexue, 2009Aerobic granules were cultivated with synthetic wastewater and were added in the course of aerobic starvation. Results showed that EPS produced by aerobic granules was composed of 40% biodegradable and 60% nonbiodegradable EPS. Among these, only biodegradable EPS could be utilized by their producers, while nonbiodegradable EPS contributed to maintain ...

In Situ Characterization of Extracellular Polymeric Substances (EPS) in Biofilm Systems
1999Historically, microbial polysaccharides were studied for three reasons. First, polysaccharides represent a structural feature of the microbial cell; therefore they were investigated for pure and basic research interests. Second, polysaccharides were recognized as antigen determinants of the microbial cell surface; the knowledge of their structure was ...
