These biotic groups secrete matrices of biomacromolecules called Extracellular Polymeric Substances (EPSs), which enhance their ability to withstand extreme environmental conditions. EPSs are mainly composed of exopolysaccharides, proteins, lipids and nucleic acids, and exhibit assorted activities due to ...

The presence of extracellular polymeric substances (EPSs), which are the main component of the WAS floc matrix [1], is one of the major causes of the low dewaterability of WAS. According to Chen et al. [2] and Jin et al. [3], the presence of EPSs led to additional interstitial ...
extracellular polymeric substances (epss) are involved in both detrimental and beneficial consequences of microbial aggregates such as biofilms, flocs and biological sludges. in biofouling, they are responsible for the increase of friction resistance, change of surface properties such as hydrophobicity, ro...
Extracellular polymeric substances (EPSs) can be defined as renewable, high molecular weight polymeric materials produced by bacteria and microorganisms. EPSs are composed of primarily polysaccharides, proteins with minor amounts of nucleic acids, lipids, and humic substances. Cyanobacterial EPSs have a ...
Bacterial extracellular polymeric substances (EPSs) play an important role in the formation and stabilization of bioaggregates, such as biofilm, microbial flocs and granules. Thus, the selection of appropriate extraction method is of critical importance, which may affect the yield, compositions and pro...
1.Based on the effect of Fe ion on the formation of extracellular polymeric substances(EPS) in biofilm,the promotion mechanism of Fe ion for biofilm formation on suspended carrier was studied through contrast test.从铁离子影响生物膜中胞外聚合物形成的角度,通过对比试验研究了铁离子促进填料挂膜的机理...
