Insights into the Viscoelastic Peculiarities of Cyanobacterial Extracellular Polymeric Substance (EPS)

Extracellular polymeric substances (EPSs) can be defined as renewable, high molecular weight materials produced by bacteria and microorganisms. EPSs are composed of primarily polysaccharides, proteins with minor amounts nucleic acids, lipids, humic substances. Cyanobacterial have a significant physiological effect on bloom formation stress tolerance in adverse conditions. Therefore, cyanobacterial EPS has an important factor for aquatic life, environment human life. For these reasons, determining the structure structure-property relationships is understanding its behavior performance. In this study, identification relationships, thermal viscoelastic properties EPS, X-ray diffraction analysis, differential analysis dynamic mechanical (DMA) been performed. Viscoelastic interpreted certain DMA parameters at fixed frequency depending temperature to understand performance EPS. Because termal stability, present great ecological importance well market potential industrial applications.
