high quality role of extracellular polymeric substances (eps)

  • extracellular polymeric substance

    Extracellular polymeric substance

    Extracellular polymeric substances (EPSs) are natural polymers of high molecular weight secreted by microorganisms into their environment. EPSs establish the functional and structural integrity of biofilms, and are considered the fundamental component that determines the physiochemical properties of a biofilm.

    Extracellular Polymeric Substance. Extracellular polymeric substances (EPS) are fundamental constituents of biofilms and can improve the biofilm community's ability to scavenge both water and nutrients from the environment when either are limiting, promoting persistent metabolism in atypical conditions.

    Extracellular polymeric substances (EPS) played an important role in flocculation of microalgae. Nevertheless, no universal method was reported for EPS extraction from microalgae. In the study, a microalga with high self-flocculating efficiency was isolated and identified as Neocystis mucosa SX.

    Characterization of the extracellular polymeric substances

    The origin of dolomite –a common mineral in the geological record– is the subject of an ongoing debate. Among different hypotheses, it has been proposed that extracellular polymeric substances (EPS) excreted by microbes include organic molecules that catalyze the incorporation of Mg in the carbonate mineral.

EPSs produced by bacteria play an important role in control-ling the flocculation and floc properties, including settling and dewatering (Bura et al., 1998). EPSs are macromolecular com-pounds that are found in the intercellular spaces of microbial

    Abstract. This research paper deals with the evolution of the extracellular polymeric substances (EPS) produced in the mixed liquor of two 25 L bench-scale membrane bioreactors (MBRs), with micro (MF-MBR) and ultrafiltration (UF-MBR) submerged membranes.

    Pyocyanin Promotes Extracellular DNA Release in Pseudomonas

    Bacterial adhesion and biofilm formation are both dependent on the production of extracellular polymeric substances (EPS) mainly composed of polysaccharides, proteins, lipids, and extracellular DNA (eDNA). eDNA promotes biofilm establishment in a wide range of bacterial species. In Pseudomonas aeruginosa eDNA is major component of biofilms and is essential for biofilm formation and stability

    Mapping of Heavy Metal Ion Sorption to Cell-Extracellular

    Biofilms, organic matter, iron/aluminum oxides, and clay minerals bind toxic heavy metal ions and control their fate and bioavailability in the environment. The spatial relationship of metal ions to biomacromolecules such as extracellular polymeric substances (EPS) in biofilms with microbial cells and biogenic minerals is complex and occurs at the micro- and submicrometer scale.
