  • Analysis of the functional characteristics of marine exopolysaccharides and melanins.
  • Evaluation of the material properties of polyhydroxyalkanoates.

Main Results:

  • Marine exopolysaccharides and melanins exhibit properties suitable for emulsifiers and adhesives.
  • Polyhydroxyalkanoates serve as a base material for biodegradable plastics.
  • Marine biopolymers represent a significant, yet underdeveloped, biological resource.

Conclusions:

  • Biopolymers from marine prokaryotes offer significant commercial potential.
  • Exploiting these marine resources can lead to innovative products.
  • Further research and development are needed to fully utilize this biological resource.
