Abstract
Using high resolution molecular technique of atomic force microscopy we address the extracellular polymer production of Adriatic diatom Cylindrotheca closterium analyzed at the single cell level and the supramolecular organization of gel phase isolated from the Northern Adriatic macroagregates. Our results revealed that extracellular polysaccharides freshly produced by marine diatoms can self-assemble directly to form gel network characteristic of the macroscopic gel phase in the natural aquatorium. Based on the experiments performed with isolated polysaccharide fractions of C. closterium and of macroagreggates gel phase we demonstrated that the polysaccharide self-assembly into gel network can proceed independent on any bacterial mediation or interaction with inorganic particles.
